Michael Graziano: Rethinking Consciousness? Attention Schema Theory & the Science of Subjectivity
Michael Graziano is a scientist and novelist who is currently a Professor of Psychology and Neuroscience at Princeton University. He’s a best-selling author and has written several books including “Consciousness and the Social Brain”, “Re-thinking Consciousness”, “The Spaces Between Us”, and much more. His scientific research at Graziano Lab focuses on the brain basis of awareness. He has proposed the “attention schema theory” (AST), an explanation of how, and for what adaptive advantage, brains attribute the property of awareness to themselves.

SARS-CoV-2 can cause buildup of Alzheimer’s-related peptides in retina
A new Yale study has found a promising target for treating the brain fog that can follow COVID-19 and offers new insight into a hypothesis about the origin of Alzheimer’s disease.
One of the hallmarks of Alzheimer’s disease is the presence of plaque formed by the buildup of amyloid beta peptides (short chains of amino acids) in and around brain cells. Some researchers suspect that amyloid beta, which is structurally similar to antimicrobial peptides, protects the brain against bacteria, viruses, parasites, and fungal infections. Because the blood-brain barrier tends to lose its integrity in Alzheimer’s disease patients, the accumulation of amyloid beta might be a signal that pathogens are infiltrating the brain.
In a new study published in Science Advances, Yale researchers investigated whether infection by SARS-CoV-2—the virus that causes COVID-19—can trigger Alzheimer’s disease-like amyloid beta buildup, leading to neurological impairments like brain fog.
