Interview: How does your brain perceive the world around you?

2022-06-19T16:27:00-04:00June 19th, 2022|

Neuroscientists have struggled for decades to fully understand how the brain takes in information from the outside world and makes near instantaneous decisions. Dr. György Buzsáki is the Biggs Professor of Neuroscience in the Department of Neuroscience and Physiology and professor in the Department of Neurology at NYU. He joins host Krys Boyd to discuss his research into the way the brain computes signals in order to better understand human decision making. [...]

The Chinese edition of The Brain From Inside Out is released

2022-06-03T02:47:46-04:00June 3rd, 2022|

Buzsáki, G. The Brain from Inside Out - In Chinese Is there a right way to study how the brain works? Following the empiricist’s tradition, the most common approach involves the study of neural reactions to stimuli presented by an experimenter. This ‘outside-in’ method fueled a generation of brain research and now must confront hidden assumptions about causation and concepts that may not hold neatly for systems that act and react. György [...]

Explanation of the log-dynamic brain, by Artem Kirsanov

2022-05-18T17:18:54-04:00May 18th, 2022|

Logarithmic nature of the brain In this video, Artem talks about the fundamental role of the lognormal distribution. First, he derives it through the Central Limit Theorem and then explores how it supports brain operations on many scales - from cells to perception. Our literature on lognormal distributions inspired the video.

The Brain Doesn’t Think the Way You Think It Does – our contribution

The Brain Doesn’t Think the Way You Think It Does, by Jordana Cepelewicz Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging. "We have to look at brain mechanisms first, and why and how those things evolved", György Buzsáki, NYU School of Medicine. https://www.quantamagazine.org/mental-phenomena-dont-map-into-the-brain-as-expected-20210824/

Science News: Ripples in rats’ brains tied to memory may also reduce sugar levels

2021-08-13T02:44:59-04:00August 13th, 2021|

Ripples of nerve cell activity that lock in memories may have an unexpected job outside of the brain: Dropping blood sugar levels in the body. Just after a burst of ripples in a rat’s hippocampus, sugar levels elsewhere in the body dipped, new experiments show. The curveball results, published August 11 in Nature, suggest that certain types of brain activity and metabolism are entwined in surprising and mysterious ways.

A signal to synchronize thought with metabolism

2021-08-13T02:49:33-04:00August 12th, 2021|

A signal to synchronize thought with metabolism In a brain structure called the hippocampus, sharp wave-ripples — oscillatory hallmarks of an ‘offline’ mode of cognitive processing — have been found to predict dips in glucose concentrations in the body.
