Cryonics Revival Scenarios & Potential Roadmaps & Hypotheses

For decades, researchers have debated whether brain cells called astrocytes can signal like neurons. Researchers recently published the best evidence yet that some astrocytes are part of the electrical conversation. A brain is nothing if not communicative. Neurons are the chatterboxes of this conversational organ, and they speak with one another by exchanging pulses of […]

The “circuit” metaphor of the brain is as indisputable as it is familiar: Neurons forge direct physical connections to create functional networks, for instance to store memories or produce thoughts. But the metaphor is also incomplete. What drives these circuits and networks to come together? New evidence suggests that at least some of this coordination […]

Multiple interacting spirals organize brain activity flow. Credit: Gong et al.

The research, published today in Nature Human Behaviour, indicates these ubiquitous spirals, which are brain signals […]

Three new books lay bare the weirdness of how our brains process the world around us. By Matthew Hutson August 25, 2021 https://www-technologyreview-com.cdn.ampproject.org/c/s/www.technologyreview.com/2021/08/25/1032121/brains-controlled-hallucination/amp/

To perform various maintenance and protective tasks, the brain contains a large population of microglia alongside its neurons. These glia include astrocytes, which, among their many other tasks, are responsible for aiding neurons with metabolism. For example, after a neuron fires, the glutamate used in that firing is taken up by an astrocyte, processed into […]

The phenomenon of criticality can explain the sudden emergence of new properties in a wide range of complex systems, from avalanches to flocks of birds to stock market crashes. Neuroscientists are now seeking evidence that criticality is at work in the brain’s networks of neurons. https://www.quantamagazine.org/videos/could-one-physics-theory-unlock-the-mysteries-of-the-brain/

A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations. Some neuroscientists favor a predictive coding explanation for how the brain works, in which perception may be thought of as a “controlled hallucination.” This theory emphasizes the brain’s expectations […]

A commonly held view is that when brain cells die, it is an irreversible, final state. Within less than 40 seconds of oxygen deprivation, the human brain’s interneuronal activity ceases and becomes electrically inactive. The brain’s ion gradients begin to degrade within minutes, as depolarization proliferates as a surge of electrochemical energy is released as […]
