Gaia-Based Theosophy: Conception and Birth of the Living Earth

Posted by in categories: biological, climatology, evolution, neuroscience, sustainability

“The Earth has entered a radically new era, understood by scientists as the Anthropocene: a time when humanity reckons with massive geologic and biospheric forces we, as anthropos, have set in motion. The agency of Nature and the reality of humanity as a collective geologic force is becoming understood differently, even within the Western paradigm. It is a new world our children will inherit, for if humanity is to survive, we must come into new realizations of our place within the planetary life-support systems. To lay a path for future generations through the evolutionary steps that humanity must now take to learn to live in balance with the planet, science must come to balance with Spirit.” ―Oberon Zell, GaeaGenesis.

In the early 1970s, celebrated philosopher and mystic Oberon Zell was the first to propose the radical idea that the biosphere of Earth was a single living superorganism. His initial article on the subject electrified the emerging modern movement of Earth-based spirituality, generating volumes of correspondence, lecture tours, and further articles in various journals and books.

How An “Ocean” in Your Brain Helps Transmit Information

Posted by in categories: biological, computing, neuroscience

For years, the brain has been thought of as a biological computer that processes information through traditional circuits, whereby data zips straight from one cell to another. While that model is still accurate, a new study led by Salk Professor Thomas Albright and Staff Scientist Sergei Gepshtein shows that there’s also a second, very different way that the brain parses information: through the interactions of waves of neural activity. The findings, published in Science Advances on April 22, 2022, help researchers better understand how the brain processes information.

“We now have a new understanding of how the computational machinery of the brain is working,” says Albright, the Conrad T. Prebys Chair in Vision Research and director of Salk’s Vision Center Laboratory. “The model helps explain how the brain’s underlying state can change, affecting people’s attention, focus, or ability to process information.”

Researchers have long known that waves of electrical activity exist in the brain, both during sleep and wakefulness. But the underlying theories as to how the brain processes information—particularly sensory information, like the sight of a light or the sound of a bell—have revolved around information being detected by specialized brain cells and then shuttled from one neuron to the next like a relay.

Anesthetic Has Been Found to Drastically Change Primate Brain Waves. Here’s How

Posted by in category: neuroscience

The widely used anesthetic propofol has a dramatic effect on the oscillating waves circulating through the brain, a new primate study shows – important findings for understanding more about our bodies under anesthesia, and ensuring it remains safe to use.

When we’re conscious, the brain is dominated by higher frequency waves (beta waves) – but under the influence of propofol-based general anesthesia, it seems that very slow-frequency traveling waves (delta waves) are much more common.

Moving through the cortex – the outermost layer of brain tissue – these waves also shift from traveling in all kinds of different directions to all pointing the same way. Some beta waves still exist, but also in small pockets not covered by delta waves.

New Brain Learning Mechanism Calls for Revision of Long-Held Neuroscience Hypothesis

Summary: Experimental observations conclude learning is mainly performed by neural dendrite trees as opposed to modifying solely through the strength of the synapses, as previously believed.

Anesthetic Drastically Diverts the Travels of Brain Waves

Posted by in category: neuroscience

Summary: New findings reveal how anesthesia-induced unconsciousness differs from normal sleep in relation to delta wave activity in the brain.

Imagine the conscious brain as a sea roiling with the collisions and dispersals of waves of different sizes and shapes, swirling around and flowing across in many different directions. Now imagine that an ocean liner lumbers through, flattening everything that trails behind with its powerful, parting wake.

Cybernetic Theory: Interpretive Model of Everything We Call the Universe

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

Another key insight of Cybernetic Theory can be referred to as “Mind Over Substrates”: Phenomenal “local” mind is “cybernetically” emergent from the underlying functional organization, whereas holistic “non-local” consciousness is transcendentally imminent. Material worlds come and go, but fundamental consciousness is ever-present, as the multiverse ontology is shown to be testable. From a new science of consciousness to simulation metaphysics, from evolutionary cybernetics to computational physics, from physics of time and information to quantum cosmology, this novel explanatory theory for a deeper understanding of reality is combined into one elegant theory of everything (ToE).

If you’re eager to familiarize with probably the most advanced ontological framework to date or if you’re already familiar with the Syntellect Hypothesis which, with this newly-released series, is now presented to you as the full-fledged Cybernetic Theory of Mind, then this 5-book set will surely present to you some newly-introduced and updated material if compared with the originally published version and can be read as a stand-alone work just like any book of the series:

Whole-Brain Preclinical Study Illuminates How Epileptic Seizures Originate

Posted by in categories: biotech/medical, neuroscience

Summary: Seizures originate from an excess of excitatory over inhibitory neural activity in confined regions of the brain, and spread only when they overcome strong inhibitory activity in surrounding regions.

New evidence from a zebrafish model of epilepsy may help resolve a debate into how seizures originate, according to Weill Cornell Medicine and NewYork-Presbyterian investigators. The findings may also be useful in the discovery and development of future epilepsy drugs.

Widespread Brain Receptor Hides Surprising Mechanism of Action

Posted by in categories: biotech/medical, neuroscience

Summary: Glutamate binds to the subunits of its receptor only in specific patterns. The findings upend previous belief that each subunit binds glutamate independently and points to a new level of complexity in neurotransmission and drug response.

One of the most important molecules in the brain doesn’t work quite the way scientists thought it did, according to new work by researchers at Columbia University Vagelos College of Physicians and Surgeons and Carnegie Mellon University.
