Scientists have successfully tested in the lab a tiny biosensor they developed that can detect biomarkers tied to traumatic brain injuries. In a study published recently in the journal Small, the Ohio State University researchers say their waterproof biosensor includes an “unprecedented combination of features” that may allow it to detect changes in the concentrations of various...

How Gut Neurons Communicate with the Brain to Control Thirst
Drinking a glass of water is often sufficient to quench thirst after exercising. But while the sensation of thirst may be satiated after just a few minutes of drinking, the process of rehydration actually takes around half an hour. The delay occurs because the brain receives signals that you drank water before the body is fully rehydrated...

Research reveals new links between brain over-activity and schizophrenia symptoms
by University of Nottingham Credit: Pixabay/CC0 Public Domain New research has shown that over-activity in a specific area of the brain is linked to certain symptoms of schizophrenia, opening up possibilities for the development of more targeted treatments. Researchers from the University of Nottingham found that faulty inhibitory neurotransmission and abnormally increased activity in the...

How the brain knows when to take out the trash
by Bill Hathaway, Yale University Credit: CC0 Public Domain The brain has its own housekeeping service, a sophisticated mechanism that cleans up debris that is left over from cellular activity. But scientists have had a hard time figuring out exactly how the brain knows when to initiate this cellular “trash pickup.” A Yale-led team of...

Team Shows How Memories Are Stored in The Brain, With Potential Impact on Conditions Like PTSD
Fish that glow; a tailor-made microscope; a new way to catalog science. After six years, researchers produce the first snapshots of memory in a living animal. What physical changes occur in the brain when a memory is made? A team of researchers at the University of Southern California has, for the first time, answered this...

Cells Deep in Your Brain Place Time Stamps on Memories
By Abdulrahman Olagunju on December 29, 2021 Hippocampi, one in each brain hemisphere. Credit: Sebastian Kaulitzki/Science Photo Library/Getty Images How does our brain know that “this” follows “that”? Two people meet, fall in love, and live happily ever after—or sometimes not. The sequencing of events that takes place in our head—with one thing coming after another—may have something to do...

A Schematic illustrating the crossing of MAPTP301S with the Aldh1l1_eGFP-RPL10a mouse. Astrocyte TRAP-seq performed on MAPTP301S vs. WT mice (both carrying the Aldh1l1_eGFP-RPL10a allele) at 3 months (B) and 5 months (C) in the spinal cord....

The Aging Kidney Harms the Brain
A good deal of evidence points to declining kidney function as a cause of declining cognitive function in aging. There are strong correlations between loss of kidney function and risk of dementia, for example. Correlation isn’t a smoking gun in matters of aging, however: it is possible for any one of the underlying forms of molecular damage that cause aging, or...

Study sheds new light on how semantic information is organized in the brain
by Ingrid Fadelli, Medical Xpress Fig. 1: Voxels with correlated visual and linguistic semantic representations. Credit: DOI: 10.1038/s41593-021-00921-6 The human brain stores and organizes meaningful information in different regions and networks. While past neuroscience studies have examined some of these networks in great depth, the relationship and interactions between them is not yet entirely clear....
