Hobson and Friston have hypothesized that the brain must actively dissipate heat in order to process information (Virtual reality and consciousness inference in dreaming. Front Psychol. 2014 Oct 9;5:1133.). This physiologic trait is functionally homologous with the first instantation of life formed by lipids suspended in water forming micelles- allowing the reduction in entropy (heat dissipation), circumventing the Second Law of Thermodynamics permitting the transfer of information between living entities, enabling them to perpetually glean information from the environment (= evolution). The next evolutionary milestone was the advent of cholesterol, embedded in the cell membranes of primordial eukaryotes, facilitating metabolism, oxygenation and locomotion, the triadic basis for vertebrate evolution. Lipids were key to homeostatic regulation of calcium, forming calcium channels. Cell membrane cholesterol also fostered metazoan evolution by forming lipid rafts for receptor-mediated cell-cell signaling, the origin of the endocrine system. The eukaryotic cell membrane exapted to all complex physiologic traits, including the lung and brain, which are molecularly homologous through the function of neuregulin, mediating both lung development and myelinization of neurons. That cooption later exapted as endothermy during the water-land transition (Torday JS. A Central Theory of Biology. Med Hypotheses. 2015 Jul;85(1):49-57), perhaps being the functional homolog for brain heat dissipation and consciousness/mind. The skin and brain similarly share molecular homologies through the ‘skin-brain’ hypothesis, giving insight to the cellular-molecular ‘arc’ of consciousness from its unicellular origins to integrated physiology. This perspective on the evolution of the central nervous system clarifies self-organization, reconciling thermodynamic and informational definitions of the underlying biophysical mechanisms, thereby elucidating relations between the predictive capabilities of the brain and self-organizational processes.

What Causes Déjà Vu? A Glitch in the Brain of Memories from the Future? #science #spirit #physics

What Causes Déjà Vu? A Glitch in the Brain of Memories from the Future? #science #spirit #physics | Limitless learning Universe | Scoop.it

Glitches in the brain or a glimpse into the future?

You walk into a room and suddenly your brain goes fuzzy with an overwhelming wave of familiarity -- although this is a totally new experience. Like something out of a sci-fi plot, it almost seems as if you've walked into the future. Chances are, you've experienced this situation, known as déjà vu, during your life.

 

Déjà vu (French for 'already seen') episodes occurs in approximately 60 to 80 percent of people -- a phenomenon that's almost always fleeting and may manifest at any time. Despite wide-spread coverage, bursts of déjà vu are still misunderstood by the scientific community.

 

"Because there is no clear, identifiable stimulus that elicits a déjà vu experience (it is a retrospective report from an individual), it is very difficult to study déjà vu in a laboratory," said Michelle Hook, Ph.D., assistant professor in the Department of Neuroscience and Experimental Therapeutics, at the Texas A&M Health Science Center College of Medicine. "According to many studies, approximately two-thirds of individuals have experienced at least one episode of déjà vu in their life," Hook said. "Understanding how memory storage works may shed some light on why some experience it more than others."

 

Episodes of déjà vu may be closely related to how memory is stored in the brain. Retention of long-term memories, events and facts are stored in the temporal lobes, and, specific parts of the temporal lobe are also integral for the detection of familiarity, and the recognition of certain events. The takeaway: The temporal lobe is where you make and store your memories.

 

While déjà vu's connection to the temporal lobe and memory retention is still relatively unknown, clues about the condition were derived from people who suffer from temporal lobe epilepsy (a condition in which nerve cell activity in the brain is disturbed -- causing seizures). Findings suggest that déjà vu events may be caused by an electrical malfunction in the brain.

 

Epileptic seizures are characterized by dysfunctional neuron (nerve cell) activity across the brain which disrupts the electrical impulses that 'fire' neurons. These impulses can spread across the whole brain -- inducing seizures. "Clinical reports show that some patients who suffer from temporal lobe epilepsy report experiencing déjà vu, almost as a sort of warning, before an epileptic seizure event," Hook said.

 

But, what is the basis for déjà vu in healthy people without epilepsy? Some researchers describe it as a 'glitch' in the brain -- when the neurons for recognition and familiarity fire -- allowing the brain to mistake the present for the past. In fact, the same abnormal electrical impulses that contribute to epilepsy can present in healthy people. An example of this is a hyponogogic jerk (an involuntary muscle spasm that occurs as a person is falling asleep).

How the #brain produces consciousness in “time slices” interesting in a way....

How the #brain produces consciousness in “time slices” interesting in a way.... | Limitless learning Universe | Scoop.it

EPFL scientists propose a new way of understanding of how the brain processes unconscious information into our consciousness. According to the model, consciousness arises only in time intervals of up to 400 milliseconds, with gaps of unconsciousness in between. The driver ahead suddenly stops, and you find yourself stomping on your breaks before you even realize what is going on. We would call this a reflex, but the underlying reality is much more complex, forming a debate that goes back centuries: Is consciousness a constant, uninterrupted stream or a series of discrete bits – like the 24 frames-per-second of a movie reel? Scientists from EPFL and the universities of Ulm and Zurich, now put forward a new model of how the brain processes unconscious information, suggesting that consciousness arises only in intervals up to 400 milliseconds, with no consciousness in between. The work is published in PLoS Biology.

 

Consciousness seems to work as continuous stream: one image or sound or smell or touch smoothly follows the other, providing us with a continuous image of the world around us. As far as we are concerned, it seems that sensory information is continuously translated into conscious perception: we see objects move smoothly, we hear sounds continuously, and we smell and feel without interruption. However, another school of thought argues that our brain collects sensory information only at discrete time-points, like a camera taking snapshots. Even though there is a growing body of evidence against “continuous” consciousness, it also looks like that the “discrete” theory of snapshots is too simple to be true.

 

Michael Herzog at EPFL, working with Frank Scharnowski at the University of Zurich, have now developed a new paradigm, or “conceptual framework”, of how consciousness might actually work. They did this by reviewing data from previously published psychological and behavioral experiments that aim to determine if consciousness is continuous or discrete. Such experiments can involve showing a person two images in rapid succession and asking them to distinguish between them while monitoring their brain activity.

 

The new model proposes a two-stage processing of information. First comes the unconscious stage: The brain processes specific features of objects, e.g. color or shape, and analyzes them quasi-continuously and unconsciously with a very high time-resolution. However, the model suggests that there is no perception of time during this unconscious processing. Even time features, such as duration or color change, are not perceived during this period. Instead, the brain represents its duration as a kind of “number”, just as it does for color and shape.

 

Then comes the conscious stage: Unconscious processing is completed, and the brain simultaneously renders all the features conscious. This produces the final “picture”, which the brain finally presents to our consciousness, making us aware of the stimulus.
