Study reveals critical role of tRNA modifying enzyme in brain function
September 27, 2024 by Kumamoto University Loss of TRMT10A led to a decrease in the levels of initiator methionine tRNA (tRNAiMet) and a specific glutamine tRNA (tRNAGln). This reduction weakened the initiation of protein synthesis for certain brain genes and made the genetic code for glutamine harder to recognize. As a result, the production of...

Neuronal wiring’s role in brain function varies across regions, study finds
Global comparison between structural and functional connectivities. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-51395-6 Different brain regions are connected by—and interact through—networks of neurons. But the extent to which neuronal wiring drives shared function between these different regions is not well understood. Is this structure-function relationship the same throughout the brain? The same across functions? Yale researchers have...

Certain antidepressants may improve brain function, study finds
September 23, 2024 by European College of Neuropsychopharmacology Credit: Wikimedia CommonsResearchers have found that SSRI (selective serotonin reuptake inhibitor) antidepressants have the potential to improve certain cognitive functions, such as verbal memory. They measured brain function in patients before and after taking the SSRI, escitalopram, and correlated this to a drop in the level of...

New Insight Into Psilocybin’s Therapeutic Potential
Medscape Medical News Patrice Wendling July 17, 2024 A single high dose of psilocybin results in dramatic, acute, and persistent changes to the brain’s functional networks in healthy adults, results of a small randomized controlled trial show. The new findings enhance the understanding of psychedelics’ effects on human brain activity and offer insights into their...

A hearing aid could extend your brain function by years
by Julia Sarant, David Harris, Peter Busby, Jocelyn Phillips, Charlotte Anderson and Jack Hargreaves, University of Melbourne Comparative cognitive performance over 36 months for the HA and AIBL groups on the Cogstate Brief Battery. Scoring is based on speed and accuracy; therefore, increased scores indicate poorer performance. Relative to HA participants, scores for AIBL participants increased over...

Study reveals broader impact of Alzheimer’s on brain function
UNIVERSITY OF TEXAS AT DALLAS IMAGE: ALZHEIMER’S DISEASE AND AGING ARE ASSOCIATED WITH DISTINCT PATTERNS OF BRAIN NETWORK DISRUPTION. ALZHEIMER’S (LEFT) EXERTS WIDESPREAD IMPACTS ON BRAIN CONNECTIVITY, DISRUPTING BOTH HIGHER ORDER COGNITIVE NETWORKS AND SENSORY AND MOTOR NETWORKS. IN CONTRAST, HEALTHY AGING (RIGHT) IS LIMITED TO DISRUPTION OF COGNITIVE NETWORKS AND SPARES SENSORY AND MOTOR...

Brain function found to decline rapidly in years after a heart attack
By Bronwyn Thompson May 30, 2023 While age-related cognitive decline is unavoidable, it appears a heart attack might speed up the process Depositphotos Recovery from a heart attack is most often focused on lifestyle changes to support and protect cardiovascular health. But researchers out of the Johns Hopkins University School of Medicine have sounded another alarm, finding...
