The two visual streams hypothesis is a robust example of neural functional specialization that has inspired countless studies over the past four decades. According to one prominent version of the theory, the fundamental goal of the dorsal visual pathway is the transformation of retinal information for visually-guided motor behavior. To that end, th...

Information processing in microtubules is an open question that has not been properly addressed yet. It was suggested that microtubules could store and process information in the nervous system or even support consciousness. The unicellular organism, Paramecium caudatum, that has a microtubular structure but does not have a neuron or neural network...

The two visual streams hypothesis is a robust framework that has inspired many studies in the past three decades. One of the well-studied claims of this hypothesis is the idea that the dorsal visual pathway is involved in visually guided motor behavior, and it is operating with a short memory. Conversely, this hypothesis claims that the ventral vis...

Background: A proper explanation for perceptual symptoms in neurodegenerative disorders including Alzheimer's disease and Parkinson's disease (PD) is still lacking. Objective: This study aimed at investigating the imbalance between 'bottom-up' and 'top-down' information flow (IF) and processing in PD in relation with visual hallucination symptom...

Predictive coding theory suggests that conscious perception results from the interaction between top-down and bottom-up signals in the brain. However, the electrophysiological signatures of top-down predictions are not clear yet. Here, we cued subjects to expect a certain perceptual state in a binocular rivalry task and quantitatively analyzed thei...

Learning is a fundamental process that involves complex neural systems. However, microorganisms without a nervous system have also been shown to have learning abilities. Specifically, Paramecium caudatum has been reported to form associations between lighting conditions and cathodal shocks in its swimming medium. We replicated previous reports on t...

The neurocognitive substrates of decision making in the context of chess has appealed to the interest of investigators for decades. Expert and beginner chess players are hypothesized to employ different functional brain networks when involved in episodes of critical decision making while playing chess. Cognitive capacities including, but not restri...

The neurocognitive substrates of decision making (DM) in the context of chess has appealed to researchers' interest for decades. Expert and beginner chess players are hypothesized to employ different brain functional networks when involved in episodes of critical DM upon chess. Cognitive capacities including, but not restricted to pattern recogniti...

Functional significance of the neural oscillations has been debated since long. In particular, oscillations have been suggested to play a major role in formation of communication channels between brain regions. It has been previously suggested that gamma coherence increases during communication between hemispheres when subjects perceive a horizonta...

Recent advances in brain and cognitive science studies have revolutionized concepts in neural dynamics, regulating mechanisms, coding systems and information processing networks which govern our function and behavior. Hidden aspects of neurological and psychiatric diseases are being understood and hopes for their treatment are emerging. As such, ad...

Background: None-Chemical Distant Cellular Interactions (NCDCI) are among the unexplained issues in cell biology. One example of such interactions is the biophoton-induced growth. In this process, photon emissions from one cell can induce mitosis in other cells while they are chemically separated. This effect is evident among many species. Hypothes...
Conference Paper
Full-text available
Different types of neural dynamics have been proposed to account for the process of conscious perception. One of the most popular hypotheses is that the gamma band synchronization can bind the information across the cortex and create consciousness. On the other hand, recent lines of evidence suggest that the amplitude of the gamma waves are being m...

Bistable perception is a form of visual illusion that is widely used in the context of brain research. The spinning dancer illusion is a form of bistable perception that can be used to study the perception of motion and rotation. However, the underlying mechanism of such bistability is not fully understood. To determine the possible mechanisms invo...
Conference Paper
Sleep is one of the fundamental and basic processes in the brain and transition between sleep-wake states is probably the most important transition that heppens in the brain. Sleep-wake transition is similar with anesthesia since both include loss of consciousness. Previous models have shown that modulation of GABAa receptors in thalamocortical net...

Entanglement is an integral part of the quantum information processing and quantum computations that have been proposed to take place in the brain. Microtubules and photons are agents that have been mainly discussed as related factors in quantum computations of the brain. In the present article, we report the dynamical behaviour of entanglement bet...

Background: Sun protection materials have been one of the major concerns in pharmaceutical industry since almost one century ago. Various materials have been found to have such an effect but there are still many unknown substances that have not be discovered. Objective: To introduce a novel mineral-based sun lotion with considerable UV absorption...

BCI is one of the most intriguing technologies among other HCI systems, mostly because of its capability of recording brain activities. Spelling BCIs, which help paralyzed people to maintain communication, are one of the striking topics in the field of BCI. In this scientific a spelling BCI system with high transfer rate and accuracy that uses SSVE...

Question
Orch-OR theory for consciousness asserts that the microtubules are the neural structures that support the quantum effects. Let's assume that it is true. Therefore, if they have to play a role in the brain, they need to effect the signal transmission in the brain. Is there any indication for such an effect?
Question
does anyone has some Ideas about the relationship between these two phenomena?
aren't they the same thing with different names?
if they are not, what is their exact difference?
Question
The criticality hypothesis asserts that the brain is a critical system, like a paramagnetic material in the critical temperature. being in the critical state can maximize the repertoire of a system (physicists call it susceptibility) beside unpredictability and coherence of states.
There are experimental evidences for it, neural avalanches show a great similarity to critical systems. Dante chialvo and other physicists provided a good understanding of the critical brain in recent years.
BUT, can Criticality hypothesis spark a new understanding in the field of consciousness research?

Question
The measure "phi" as the capability of a system to produce integrated information seems to just define necessary connections. However, it seems that it doesn't indicate what kind of neural dynamics integrates the whole existing information all across a complex. is it synchronization, recurrent activity or something else?
Question
Since there are some good simulations of the neural circuits using this classic model, I'm curious about any reference or guideline that would be useful for this topic.
The attached article is one of them (written by researchers of the MIT etc.)
