Surprising study shows reduced neuronal activity extends life

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Say this about the kinds of molecular mayhem that we know underlie aging: Mechanisms like whether the ends of chromosomes fray (bad) and whether genes’ on-off status breaks down (really bad) at least sound like plausible ways to impair vital organs, from skin to brains and hearts, and produce the whole sorry mess known as aging.

On Wednesday, scientists reported a driver of aging that, in contrast, even the lead researcher diplomatically calls “counterintuitive”: neuronal activity. Aging, of course, affects the brain. But the brain seems to affect aging, too, they found: In creatures from worms to mice to people, high levels of neuronal firing spell a shorter life span. Lower levels — naturally, or due to drugs that dampen neurons’ activity — increase longevity.

The discovery4 was so surprising that it’s taken two years to be published (in Nature) because of how much additional data the outside scientists reviewing the study requested. Geneticist Bruce Yankner of Harvard Medical School, who led the research, understood their skepticism. “If you say you have a cat in your backyard, people believe you,” he said. “If you say you have a zebra, they want more evidence.”

Scientists have discovered that resident bacteria of the intestine, collectively known as the gut microbiome, can influence the ability to overcome fear.

New study expands understanding of the ‘gut-brain axis’. Paul Biegler reports.

The Ouroboros Code: Self-Reference is the Name of the Game

Posted by in categories: computing, cosmology, mathematics, neuroscience, quantum physics

“If you are not convinced by the idea of reductive materialists that consciousness magically emerges from complexity in material structures or processes or if you are not satisfied with the viewpoint of idealists that matter is a mere thought form, then the present hypothesis may be something for you,” writes Dr. Antonin Tuynman when presenting his new book The Ouroboros Code. https://www.ecstadelic.net/top-stories/the-ouroboros-code-se…f-the-game #OuroborosCode

In “The Ouroboros Code” I will address the cybernetic dynamics of consciousness. Starting from the premise that Consciousness is the Ontological Primitive, I will propose mechanisms which may explain how a digital mathematical and material existence can be generated. Digging into Category Theory, Computational Simulacra and Quantum Computing, I will explore the mechanics of self-sustaining self-referential feedback loops as the Modus Operandi of Consciousness.

Let’s dive in the vortex of kaleidoscopic reflections, the wormhole of a dazzling “mise-en abyme” of recursiveness and the roller-coaster of the quantum non-locality. Explore the map which is the territory simultaneously by drawing your map of maps. Discover the non-dual bridge closing the gap between Science and Spirituality.

Landmark study links excessive neural activity with shorter lifespan

Posted by in categories: life extension, neuroscience

After almost two years mired in extensive peer review, a landmark new study just published in the prestigious journal Nature is strongly associating excessive neural activity with shorter lifespans. The study suggests a protein known to suppress neural excitation affects a number of longevity pathways, effectively slowing the aging process.

The impressive research started several years ago with a gene expression study of post-mortem human brain tissue from hundreds of subjects. All the subjects were cognitively normal at the time of death. Bruce Yankner, senior author on the new study, says one thing quickly stood out to his team – the longer a person lived, the lower their expression of genes connected to neural excitement.

More specifically, the researchers identified upregulation of a protein called REST in the brains of those longest-lived subjects. REST first came to the attention of the research team back in 2014. The protein’s role in the brain was generally thought to only play a part in prenatal neurodevelopment, regulating the expression of genes in a developing brain.

The idea that everything from spoons to stones is conscious is gaining academic credibility

Posted by in categories: neuroscience, particle physics, quantum physics

The biggest problem caused by panpsychism is known as the “combination problem”: Precisely how do small particles of consciousness collectively form more complex consciousness? Consciousness may exist in all particles, but that doesn’t answer the question of how these tiny fragments of physical consciousness come together to create the more complex experience of human consciousness.

Any theory that attempts to answer that question, would effectively determine which complex systems—from inanimate objects to plants to ants—count as conscious.

An alternative panpsychist perspective holds that, rather than individual particles holding consciousness and coming together, the universe as a whole is conscious. This, says Goff, isn’t the same as believing the universe is a unified divine being; it’s more like seeing it as a “cosmic mess.” Nevertheless, it does reflect a perspective that the world is a top-down creation, where every individual thing is derived from the universe, rather than a bottom-up version where objects are built from the smallest particles. Goff believes quantum entanglement—the finding that certain particles behave as a single unified system even when they’re separated by such immense distances there can’t be a causal signal between them—suggests the universe functions as a fundamental whole rather than a collection of discrete parts.
