Researchers have identified how variations in a gene called TRIO can influence brain functions and result in distinct neurodevelopmental diseases. The study, published in the journal eLife, could pave the way for future therapeutic developments.

TRIO encodes a diverse group of proteins that control the function and structure of the cytoskeleton—a cell’s internal scaffolding. Rare damaging variants in this gene have been identified in individuals with intellectual disability, autism spectrum disorder, schizophrenia, and related disorders. However, the mechanisms underlying the associations aren’t yet understood.

“It’s really extraordinary that different variants in this single gene can have such dramatically different effects on brain development and function,” says Anthony Koleske, Ph.D., Ensign Professor of Molecular Biophysics and Biochemistry at Yale School of Medicine (YSM) and the study’s senior author.

A study tracking 805 Brazilians in their 50s over an eight-year period has concluded that greater focus on hearing health may play a crucial role in preventing dementia. A major study from Brazil has found that people in their 50s with hearing loss face a greater risk of cognitive decline. The fi

Slight variations in a person’s pulse rate could give clues about the likelihood of future cognitive decline, according to a new study, potentially giving us a valuable new test for cognitive problems that would be quick and easy to run.

This is something that researchers invest a lot of time in, because knowing when cognitive decline might start, and how it may progress, means better support and more clarity for those involved. Along the way, it also reveals new insights into how these conditions develop, and how they might be stopped for good.

In this study, an international team analyzed pulse rate data across a night of sleep from 503 individuals with an average age of 82. Cognitive tests were also carried out around that same time, as well as in at least one follow-up visit.

Researchers have discovered that nitrous oxide can safely enhance the delivery of gene therapy to the brain by making the blood-brain barrier (BBB) more permeable when paired with focused ultrasound (FUS).

In recent years, scientists discovered something strange: When mice with Alzheimer’s disease inhale menthol, their cognitive abilities improve.

It seems the chemical compound can stop some of the damage done to the brain that’s usually associated with the disease.

In particular, researchers noticed a reduction in the interleukin-1-beta (IL-1β) protein, which helps to regulate the body’s inflammatory response – a response that can offer natural protection but one that leads to harm when it’s not controlled properly.

CRISPR-TO, a system for programmable control of spatial localization of cellular RNAs, is presented and enables functional investigation of endogenous RNA localization in diverse living cells.

The neocortex is highly susceptible to metabolic dysfunction. When exposed to global ischemia or anoxia, it suffers a slowly propagating wave of collective neuronal depolarization that ultimately impairs its structure and function. While the molecular signature of anoxic depolarization (AD) is well documented, little is known about the brain states that precede and follow AD onset. Here, by means of multisite extracellular local field potentials and intracellular recordings from identified pyramidal cells, we investigated the laminar expression of cortical activities induced by transient anoxia in rat primary somatosensory cortex. Soon after the interruption of brain oxygenation, we observed a well-organized sequence of stereotyped activity patterns across all cortical layers.

The neurophysiological footprint of brain activity after cardiac arrest and during near-death experience (NDE) is not well understood. Although a hypoactive…
