Background: Physical exercise has been found to impact neurophysiological and structural aspects of the human brain. However, most research has used animal models, which yields much confusion regarding the real effects of exercise on the human brain, as well as the underlying mechanisms. Objective: To present an update on the impact of physical...

Introduction: In the last decades, different studies have investigated the effects of exercise or physical activity (PA) on cognitive functions and academic performance in children and adolescents. But given the inconsistencies regarding methodologies and the fact that many studies do not have controlled or randomized designs, a more recent review...

Yoga is an ancient mind-body practice originated in India more than 2.000 years ago and is described systematically early on. The research on the psychophysiological benefits of yoga in children has been found to improve concentration, attention, memory, resilience, mood, self-control, academic performance, psychomotor and cardiac functions, as wel...

The evolutionary hypothesis of endurance running states that movement played a crucial role in the emergence of typically human anatomical features, as well as in the shaping and structure of the human brain. The close relationship between exercise and human evolution is evidenced by the fact that inactivity make us sick. Effectively, the human bod...

. Yoga is a holistic system of varied mind-body practices that can be used to improve mental and physical health and it has been utilized in a variety of contexts and situations. Educators and schools are looking to include yoga as a cost-effective, evidence-based component of urgently needed wellness programs for their students. Objectives . The p...

Introduction: Yoga is a holistic system of different mind–body practices that can be used to improve mental and physical health. It has been shown to reduce perceived stress and anxiety as well as improve mood and quality of life. Research documenting the therapeutic benefits of yoga has grown progressively for the past decades and now includes con...

Resumen La presente revisión discute la literatura actual sobre los efectos de la meditación, especial-mente la reducción del estrés basada en la conciencia plena, sobre los niveles de ansiedad de sujetos que sufren trastornos de este tipo. En este estudio se concluye que la meditación podría efectivamente reducir los síntomas de ansiedad y que tam...

The present review discussed the current literature on the effects of meditation, primarily mindfulnessbased stress reduction, on anxiety levels of subjects suffering from anxiety-related disorders. This study has concluded that meditation could effectively reduce symptoms of anxiety and might also work in adjunction with cognitive-behavioral thera...

Introdução: Devido aos seus conhecidos efeitos no corpo e mente, o yoga tem sido alvo de investigações cientificas há décadas. A maioria dos estudos relacionados evidencia a efetividade destas técnicas no tratamento de transtornos mentais como ansiedade, pânico e depressão. O yoga tem sido considerado um método preventivo e seguro, capaz de represe...

Over the last years, studies have shown that a great number of individuals will experience some kind of anxiety disorder on a continuing or recurring basis. Complementary therapies such as yoga have been proved to significantly reduce anxiety symptoms. Therefore, the goal of this study was to discuss the use of yoga as an intervention for treating...

The relationship between physical activity and mental health has been widely investigated, and several hypotheses have been formulated about it. Specifically, during the aging process, physical exercise might represent a potential adjunctive treatment for neuropsychiatric disorders and cognitive impairment, helping delay the onset of neurodegenerat...

The goal of the present study was to investigate electrophysiologic, qEEG, changes when individuals were exposed to a motor task. Subjects brain electrical activity was analyzed before and after the typewriting training task. For the neurophysiological variable asymmetry, a paired t-test was performed to compare each moment, pre and post-task, in t...

The early stages of visual information processing, involving the detection and perception of simple visual stimuli, have been demonstrated to be sensitive to psychotropic agents. The present study investigated the effects of an acute dose of bromazepam (3 mg), compared with placebo, on the P100 component of the visual evoked potential and reaction...

The main goal of the present study was to analyze theta asymmetry through quantitative electroencephalography (qEEG) when individuals were exposed to a sequential motor task, i.e. catching a ball. The sample was composed of 23 healthy subjects, male and female, between 25 and 40 years of age. A two-way factor Anova was applied to compare pre and po...

The aim of this study was to verify changes in absolute power (qEEG), in theta, during the catch of a free falling object. The sample consisted of 10 healthy individuals, of both genders, with ages between 25 and 40 years. A three-way ANOVA followed by Post-Hoc analysis was applied. The results demonstrated main effects for time and position. In co...

The aim of this study is analyze possible modifications in the cerebral cortex, through quantitative electroencephalography (qEEG) in patients submitted to a tendon transfer procedure (posterior tibialis) by the Srinivasan's technique. Four subjects (2 men and 2 women), 49.25 age average (SD +/ 21.4) were studied. All subjects have been through sur...

Exercise has been widely related to changes in cortical activation and enhanced brain functioning. Quantitative electroencephalography (qEEG) is frequently used to investigate normal and pathological conditions in the brain cortex. Therefore, the aim of the present study was to observe absolute power alterations in beta and alpha frequency bands af...

A three-way...

To investigate the effects of bromazepam on motor performance and electroencephalographic activity (qEEG) in healthy subjects, during the process of learning a typewriting task, with a focused attention demand. A randomized double-blind model was used to allocate subjects in one of the following conditions: placebo (n=13), bromazepam 3 mg (n=13) or...

Several studies have investigated the relationship between asymmetrical EEG activity over the frontal cortex and mood. This study aimed at investigating the association between state fluctuations in frontal alpha EEG asymmetry and state changes followed by 24 h of sleep deprivation (SD). Our results show that sleep deprivation caused a significant...
