Abstract

The heart is the symbol of life. A fetus is pronounced alive when the heart beats between 6to 8 weeks gestational life otherwise ,it is dead body. Also , life ends by the cessation of heart beats. All organs including the brain develop after the heart formation. Emryologically , the heart initially develops from the tube stage to folding stage to differentiation into chambers followed by rotation. Right and left nomenclature are misnomers , actually anterior and posterior. This project is to understand exactly the moral function of the heart and being the master of the brain in decision making.
The intellectual heart
The heart is not only a muscular blood pump.For centuries and
since the beginning of creation ,we used to say brave soldiers
have brave hearts.Embryologically,the heart develops in the
sixth week of gestational life and start beating before the
development of the brain. A process called autorhythmicity. Lif
begins with heart beating and ends when the heart stop beating
regardless of the brain function.
Wisdom,thinking and intelligence are brain functions that
begin,end and supervised by the heart .There are strong and
dynamic communication between the heart and the brain.It is
two-way dialogue with each organ continuously influencing the
other’s function.
The heart communicates with the brain and body in four
wayscreating the heart brain feed back:
Neurological communication (nervous system) by the
vagus nerve both afferent and efferent loups.
Biochemical communication (hormones) Hormones
from the heart travel in our bloodstream
Biophysical communication (pulse wave )Every time the
heart beats, it creates both pulse waves of pressure)
Energetic communication (electromagnetic fields)
electromagnetic energy which travel through the body and
to the brain. Amazingly, the heart generates a magnetic field
5000 times more powerful than that of the brain. It can be
measured six feet away from the body. It almost certainly
extends further, but this is the limit of our current sensing
equipment(15-17).
10-15% of heart donation recipients experience changes in their
tastes, personalities and memories be picking up on information
on the heart’s original owner that was stored in the heart
itself.This is attributed to functional cell memory(24).
Paul Pearsall is one of many researchers who has observed that
transplant patients who receive an organ from another person's
body may also receive much more -- what he calls their "cellular
memories." Recipients have reported inheriting everything from
the donor's food cravings to knowledge about his murderer --
information that in one case led to the killer's arrest. As a result
of these and other researchers' findings, Pearsall is now
convinced that the heart has its own form of intelligence, that we
are only rarely aware of in modern life. In his view, the heart
processes information about the body and the outside world
through an "info-energetic code" -- a profuse network of blood
vessels and cells that serves not only as our circulatory system
but as an energy information gathering and distribution system,
much like a complex telephone network. What's more, he
believes that the soul, at least in part, is a set of cellular
memories that is carried largely by our hearts. Predictably, such
views have met with opposition in the medical world. But in his
view, the implications of his theories -- that the heart
"thinks," cells remember, and communication can therefore
transcend the boundaries of time and space -- are too important
for him to dismiss.
Several recent researches showed that the heart is the source of
intelligence ,wisdom, courage and emotions.. For more than 25
years, the HeartMath Institute Research Center in the second
volume of their studies(1993 to 2016) has explored the
physiological mechanisms by which the heart and brain
communicate and how the activity of the heart influences our
perceptions, emotions, intuition and health.The heart math
institute in California is the most famous research center
exploring the role of the heart in human performance and the
heart-brain connection. Recent studies in the heart math institute
are involved in electrophysiology of intuition and the degree to
which the heart’s magnetic field, which radiates outside the
body, carries information that affects other people and even our
pets, and links people together in surprising ways. The institute
also launched the Global Coherence Initiative (GCI), which
explores the interconnectivity of humanity with Earth’s
magnetic fields.
The overview of the second volume of the heart math institute
and research center discusses the main findings of fascinating
and important role the heart plays in our personal coherence and
the positive changes that occur in health, mental functions,
perception, happiness and energy levels as people practice the
HeartMath techniques(1-11).
The anatomy and functions of the intrinsic cardiac nervous
system and its connections with the brain have been explored
extensively by neurocardiologists. In terms of heart-brain
communication, it is generally well-known that the efferent
(descending) pathways in the autonomic nervous system are
involved in the regulation of the heart. However, it is less
appreciated that the majority of fibers in the vagus nerves are
afferent (ascending) in nature. Furthermore, more of these
ascending neural pathways are related to the heart (and
cardiovascular system) than to any other organ.This means the
heart sends more information to the brain than the brain sends to
the heart. More recent research shows that the neural
interactions between the heart and brain are more complex than
previously thought more 40,000 neurons in the heart which
communicate with the brain In addition, the intrinsic cardiac
nervous system has both short-term and long-term memory
functions and can operate independently of central neuronal
command.(11.18.19).
In 1983, the heart was reclassified as an endocrine gland when a
new hormone called atrial natriuretic factor (ANF), which
affects blood vessels, kidneys, adrenal glands and regulatory
regions in the brain, was found to be being produced by the
heart(12).
Dr. J. Andrew Armour discovered the heart also contains a cell
type known as intrinsic cardiac adrenergic (ICA), which
synthesizes and releases neurotransmitters once thought to be
produced only by neurons in the brain and nerve ganglia. In 1991,
Armour introduced the concept of a functional “heart brain.” He
discovered that the heart has its own intrinsic nervous system
and that the complexity of this system is great enough to qualify
it as a “little brain” in its own right. Thus, Armour calls the
heart’s intrinsic nervous system the “little brain in the heart.”
Basically, the heart’s brain is an intricate network of several
types of neurons, transmitters, proteins, and support cells that
allow it to act independent of the “cranial brainto learn,
remember, and even feel and sense” (HeartMath 1). Information
is translated into neurological impulses by the heart’s nervous
system and sent from the heart to the brain through various
pathways. These impulses reach the medulla, located in the
brain stem, where they have a regulatory role over many of the
blood vessels, glands and organs. However, they also reach
higher centers of the brain, where they may influence
“perception, decision making and other cognitive processes”
(HeartMath 2)(18-19).
Grossman and associates (8,13,14,23))in their article titled ,a
heart and a mind :self distancing facilitates the association
between heart rate variability and wise reasoning,they
concluded that although wisdom has been long viewed as too
ethereal to be a subject of a tangible empirical inquiry, in the
last 25 years researchers have established several psychological
components of wise judgment. Recently, neuroscientists have
proposed that to understand individual differences in wisdom
one also ought to consider aspects of human physiology . The
study suggests that wisdom-related judgment is not exclusively
a function of the body or the mind. Rather, both greater heart-
rate-variability and an ego-decentered mind are required for a
wiser, less biased judgment( 15-23).

The Heart in Quran
The phrase heart carries special importance and has been used
extensively in the Holy Qur’an and narrations. But what is
meant with this phrase is not the pine-shaped physical heart
located in the left side of the chest which supports the animal
life system by continuously pumping fresh blood into various
parts of the body. Because, the Holy Qur’an relates things to
heart which are not comparable with this pine-shaped heart. e.g.:

Therefore, heart in the Holy Qur’an has been assigned
the most important privileged position, and various
psychic tasks have been related to it, namely: faith,
blasphemy, hypocrisy, reasoning, understanding, not
understanding, acceptance of truth, unacceptance of
truth, guidance, deviation, sin, intention, purification,
corruption, benevolence, aggravation, love, invocation,
negligence, fear, anger, doubt, conflict, mercy, cruelty,
regret, assurance, arrogance, jealousy, rebellion, offense,
and other similar acts
. So have they not traveled through the earth and have
hearts by which to reason and ears by which to hear? For
indeed, it is not eyes that are blinded but blinded are the
hearts which are within the breasts. [Quran 22:46]
Hearts are the main source of reason
hadith
Allah said, ‘I have prepared for My righteous slaves
(such excellent things) as no eye has ever seen, nor an
ear has ever heard nor a human heart can ever think of.’
[Bukhari]
Verily Allah does not look to your bodies nor to your
faces but He looks to your hearts. [Muslim]
Narrated Abu Hurairah, I came to the Prophet (saws) and
spread out my garment to him, then he took it and
gathered it at my heart, so I did not forget after that [any
Hadith]. [Tirmidhi
Shahr bin Hawshab said: “I said to Umm Salamah: ‘O
Mother of the Believers! What was the supplication that
the Messenger of Allah said most frequently when he
was with you?” She said: ‘The supplication he said most
frequently was: “O Changer of the hearts, make my heart
firm upon Your religion (Ya Muqallibal-Qulub, Thabbit
Qalbi Ala Dinik).’” She said: ‘So I said: “O Messenger
of Allah, why do you supplicate so frequently: ‘O
Changer of the hearts, make my heart firm upon Your
religion.’ He said: ‘O Umm Salamah! Verily, there is no
human being except that his heart is between Two
Fingers of the Fingers of Allah, so whomsoever He wills
He makes steadfast, and whomever He wills He causes to
deviate.’” [Tirmidhi]

She puzzled over this for some time, but at last a bright thought struck her. 'Why, it's a looking-glass book, of course! And if I hold it up to a glass, the words will all go the right way again.' Lewis Carroll, Through the looking-glass Marcus Aurelius, Rome's philosopher-emperor, developed a formula for coping with this troubled world. He pointed out that, if one tries to con-sider problems all-of-a-piece, one is overwhelmed. His prescription was simple: segment the reach of awareness; attend to only one facet of the situa-tion at anyone time; act upon that facet and then proceed to another. Too-much.too-soon is up-setting. Segmentation reduces the demands upon awareness and thereby produces imperturba-bility. This bit of wisdom can serve as the kernel for a modern neuropsychological theory of emotion. A theory crystallized from this kernel would look considerably different from those presently in vogue, but must account for the popuiarity of these views. Furthermore, current difficulties must be met and resolved. Current theories of emotion -in fact, psycho-logical theories in general -are couched in two major modes of discourse, two classes of concep-tual frames of reference: the social-behavioral, which includes the subjective or 'intrapsychic'; and the biological, which includes the physical, chemical, and, of course, the neurological. Terms are all too often taken from one frame of refer-ence and applied to another in haphazard and un-critical fashion. In this presentation every effort will be made to keep the two universes of dis-course clear. The assumption is, however, that because each of these conceptual universes de-notes some body of events common to both, differ-ent aspects of this common body will be illumin-ated by approaching it from different points of view. Although the initial focus of this presentation will be on the neurological realm of discourse, the proposal is not made just in neurological terms, but interdigitates the subjective-behavioral ap-proach with the neural. The neurological aspects of this proposal describe the organized operations in processing inputs and outcomes; the subjective-behavioral aspects deal with the communicative signals -termed affects, the 'feelings' and emotion-al expressions -that reflect the neural processes. It is our view that these communicative signals are, as it were, optical isomers, mirror-images (Pribram 1965) of the ongoing neural mechanisms, and that both 'processes are organized to function-in-view-of-the-same-ends (MacKay 1962). Differ-ent universes of discourse are llsed to describe the mirror-images -which may therefore display dif-..

Mindfulness meditation has beneficial effects on brain and body, yet the impact of Vipassana, a type of mindfulness meditation, on heart rate variability (HRV) - a psychophysiological marker of mental and physical health - is unknown. We hypothesised increases in measures of well-being and HRV, and decreases in ill-being after training in Vipassana compared to before (time effects), during the meditation task compared to resting baseline (task effects), and a time by task interaction with more pronounced differences between tasks after Vipassana training. HRV (5-minute resting baseline vs. 5-minute meditation) was collected from 36 participants before and after they completed a 10-day intensive Vipassana retreat. Changes in three frequency-domain measures of HRV were analysed using 2 (Time; pre- vs. post- Vipassana) x 2 (Task; resting baseline vs. meditation) within subjects ANOVA . These measures were: normalised high-frequency power (HF n.u.), a widely used biomarker of parasympathetic activity; log-transformed high frequency power (ln HF), a measure of RSA and required to interpret normalised HF; and Traube-Hering-Mayer waves (THM), a component of the low frequency spectrum linked to baroreflex outflow. As expected, participants showed significantly increased well-being, and decreased ill-being. ln HF increased overall during meditation compared to resting baseline, while there was a time*task interaction for THM. Further testing revealed that pre-Vipassana only ln HF increased during meditation (vs. resting baseline), consistent with a change in respiration. Post-Vipassana, the meditation task increased HF n.u. and decreased THM compared to resting baseline, suggesting post-Vipassana task-related changes are characterised by a decrease in absolute LF power, not parasympathetic-mediated increases in HF power. Such baroreflex changes are classically associated with attentional load, and our results are interpreted in light of the concept of 'flow' - a state of positive and full immersion in an activity. These results are also consistent with changes in normalised HRV reported in other meditation studies.

We recorded respiratory activity and electrocardiogram (ECG) together with single cell activity from the amygdala and hippocampus of epileptic patients who later received anterotemporal lobectomy. Cross‐correlation histograms were used to test for neuronal discharge timing relationships with inspiration or ECG. Linear regression was used to test for correlations of inspiratory time, respiratory period, and heart rate (HR) with tonic unit rate for each breath. Of 129 cells from 16 patients who later had resection, 89 were contralateral and 40 were ipsilateral to the resected lobe. Of the contralateral cells, 19% had a timing relationship with the cardiac cycle and only 1% had such a relationship with the respiratory cycle. Tonic correlations with HR were noted in 22% and with respiratory period and inspiratory time in 11 and 6%. Neither these percentages nor mean discharge rate differed between structures, although variance in rate was much higher on the resected side. Amygdala cells on the resected side showed more correlations with the cardiac cycle (55 vs. 20%), respiratory period (46 vs. 3%), and inspiratory time (27 vs. 7%) and were more likely to show several types of correlation. The results suggest a selective loss of ipsilateral amygdala cells and/or afferents, favoring relationships with cardiac‐ and respiratory‐related systems and a possible synaptic reorganization of remaining cardiorespiratory afferents. RÉSUMÉ Les auteurs ont enregistré l'activité respiratoire et l'électrocardiogramme en corrélation avec les décharges neuronales unitaires de l'amygdale et de l'hippocampe de patients épileptiques qui ont bénéficié secondairement d'une lobectomie temporale antérieure. Les histogrammes de corrélations croisées ont été utilisés pour évaluer les relations temporelles entre la décharge neuronale et l'inspiration ou l'électrocardiogramme. Le test de régression linéaire a été utilisé pour les corrélations entre temps d'inspiration, période expiratoire et rythme cardiaque et le taux de décharge tonique unitaire pour chaque mouvement respiratoire. Parmi 129 cellules, enregistrées chez 16 patients qui ont bénéficié secondairement d'une résection temporale, 89 étaient contralatérals et 40 étaient ipsilatérales au lobe réséqué. Parmi les cellules controlatérales, 19% présentaient une relation temporelle avec le cycle cardiaque, seulement 1% avec le cycle respiratoire. Des corrélations toniques avec le rythme cardiaque ont été trouvées chez 22%, avec la période respiratoire et le temps d'inspiration chez 11% et 6%. Aucun de ces pourcentages, ni d'ailleurs le taux de décharges moyen, ne présentait de différences selon les structures, bien que la variance du taux ait été beaucoup plus élevée du côté réséqué. Les cellules de l'amygdala du côté réséqué ont été davantage corrélées au cycle cardiaque (55% contre 20%), à la période respiratoire (46% contre 3%), et au temps d'inspiration (27% contre 7%), et présentaient plus probablement plusieurs types de corrélations. Ces résultats suggèrent qu'il existe une perte sélective des cellules amygdaliennes ipsilatérales et/ou de leurs afférents, phénomènes qui favorisent les relations avec les systèmes liés à la fréquence cardiaque et respiratoire; ces résultats suggèrent également qu'il existe une possibilité de réorganisation synaptique des afférents cardiorespiratoires résiduels. RESUMEN En enfermos que posteriormente fueron sometidos a una lobectomía temporal anterior hemos registrado la actividad respiratoria y el ECG simultaneamente con las descargas de la amígdala y del hipocampo. Se han utilizado histogramas interrelacionados para determinar la relación temporal de las descargas neuronales con la inspiración o el ECG. Se utilizó un test de regresión lineal para calcular las correlaciones del tiempo de inspiración, del periodo respiratorio y del rítmo cardiaco o con la frecuencia de unidades tónicas durante cada respiración. De las 129 células de 16 pacientes que fueron resecadas con posterioridad, 89 eran contralaterales y 40 ipsilaterales al lóbulo extirpado. De las células contralaterales, 19% tenían una relación temporal con el rítmo cardiaco y solamente 1% con el ciclo respiratorio. Se observaron correlaciones tónicas con el ritmo cardiaco en 22% y con el periodo respiratorio y el tiempo de inspiración en el 11% y en el 6% respectivamente. Ninguno de estos porcentajes y tampoco el ritmo medio de descargas, mostraron diferencias entre las estructuras a pesar de que la proyección de varianza fue mucho más elevada en el lado resecado. Las células de la amigdala del lado resecado mostraron más correlaciones con el ciclo cardiaco (55% vs. 20%), el periodo respiratorio (46% vs. 3%), el tiempo de inspiración (27% vs. 7%) y tenían tendencia a mostrar más tipos de correlación. Estos resultados sugieren una pérdida selectiva de las células de la amigdala ipsilateral y/o sus aferencias que favorecen la relación con los temas cardiacos respiratorios y también porque indican una posible reorganización sináptica de las aferencias cardiorespiratorias restantes. ZUSAMMENFASSUNG Die respiratorische Aktivität sowie das Elektrokardiogramm wurde zusammen mit neuronalen Entladungen vom Amygdalon und Hippokampus bei epileptischen Patienten abgeleitet, bei denen später eine vordere temporale Lobektomie vorgenommen wurde. Mit Hilfe von Cross‐Korrelationshistogrammen wurde der zeitliche Zusammenhang zwischen neuronalen Entladungen und Inspiration oder Elektrokardiogramm untersucht. Mit linearen Regressionen wurden die Korrelationen von Inspirationszeit, Respirationsperiode und Herzfrequenz zu tonischer Entladungsrate bei jedem Atemzug untersucht. Von insgesamt 129 abgeleiteten Zellen von insgesamt 16 Patienten, bei denen später eine Resektion vorgenommen wurde, lagen 89 kontralateral und 40 ipsilateral im resezierten Lappen. Von den Neuronen der kontralateralen Seite zeigten 19% eine zeitliche Beziehung mit dem kardialen Zyklus, und nur 1% mit dem Respirationszyklus. Eine Korrelation der tonischen Aktivität zur Herzfrequenz war bei 22% festzustellen und bei 11 bzw. 6% mit der Respirationsperiode bzw. Inspirationszeit. Zwischen den einzelnen Strukturen gab es keine Unterschiede, weder bezüglich dieser Prozentzahl, noch der mittleren Entladungsrate, obwohl die Varianz der Entladungsrate auf der resezierten Seite deutlich höher lag. Amygdalazellen der resezierten Seite zeigten eine höhere Korrelation zum kardialen Zyklus (55% gegenüber 20%), zur Respirationsperiode (46% gegenüber 3%) und zur Inspirationszeit (27% gegenüber 7%) und korrelierten mit größerer Wahrscheinlichkeit auf unterschiedliche Art und Weise. Diese Ergebnisse legen den selektiven Verlust von ipsilateralen Amygdala‐Zellen und/oder von Afferenzen nahe, die eine Beziehung zwischen kardialen und respirationsbezogenen Systemen begünstigen, sowie eine mögliche synaptische Reorganisation der verbleibenden kardio‐ respiratorischen Afferenzen.

It is becoming recognized that geomagnetic activity may influence biological processes, including the incidence of various human diseases. There is evidence that heart rate variability (HRV) may serve not only as an index of autonomic coordination of the circulation, but also as a powerful predictor of risk in apparently healthy subjects. This study focuses on the effects of geomagnetic disturbance on HRV, by comparing different indices of HRV of young, healthy men living in a subarctic area on days of low (Ap; 0-7), middle (Ap; 7-20), and high (Ap; 20-45) geomagnetic activity. The effect of geomagnetic disturbance on HRV is examined on the basis of 7-day records by Holter ECG, obtained longitudinally on 5 clinically healthy men, 21-31 years of age, in Alta, Norway (70 degree N). Frequency- and time-domain measures of HRV were analyzed for each subject on separate 24-hour spans. A graded alteration of HRV endpoints was found in association with increased geomagnetic activity. As time-domain measures of HRV, SDNNIDX and the 90% length of the Lorenz plot decreased statistically significantly on days with increased geomagnetic disturbance (p = 0.0144 and p = 0.0102, respectively). A graded decrease in frequency-domain HRV measures was also validated statistically for the total spectral power (decrease of 18.1% and 31.6% on days when 7 < Ap < 20 and 20 < Ap < 45 versus days when Ap < 7; p = 0.0013). The decrease in spectral power was mainly found at frequencies below 0.04 Hz, in the "ultra-low-frequency" (0.0001-0.003 Hz; 18.1% and 27.5% decrease, respectively; p = 0.0102) and "very-low-frequency" (0.003-0.04 Hz; 12.9% and 28.6% decrease, respectively; p = 0.0209) regions of the spectrum. The decrease in spectral power was much less pronounced around 10.5 sec ("low frequency"; N.S.) and around 3.6 sec ("high frequency"; N.S.). Evidence is provided here that HRV decreases on magnetically disturbed days, and that it does so in a dose-dependent fashion, HRV being depressed more on days when 20 < Ap < 45 than on days when 7 < Ap < 20, by comparison with days when Ap < 7. This graded response of HRV to geomagnetic activity should encourage us to search for human magnetoreceptors and for a better understanding of putative mechanisms of magnetoreception.
