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.

An article about Peter Petersen's postdoctoral study in the lab. The outcome of this question is that, today, Peter Petersen, a 37-year-old Danish neuroscientist, is working in the laboratory of world-renowned Professor György Buzsáki at New York University. And funding from the Danish Council for Independent Research and a Lundbeck Foundation postdoc scholarship made it all happen. Read the full story on the Lundbeck Foundation's website.

Metal microdrive and head cap system for silicon probe recovery in freely moving rodent

2021-05-21T09:36:32-04:00May 21st, 2021|

Metal microdrive and head cap system for silicon probe recovery in freely moving rodent High-yield electrophysiological extracellular recording in freely moving rodents provides a unique window into the temporal dynamics of neural circuits. Recording from unrestrained animals is critical to investigate brain activity during natural behaviors. The use and implantation of high-channel-count silicon probes represent the largest cost and experimental complexity associated with such recordings making a recoverable and reusable system desirable.
