Weekly Neuroscience Update

New research reveals that neurons in the visual cortex—the part of the brain that processes visual stimuli—change their responses to the same stimulus over time.

Menopause can mess with your memory, and a new study has identified four profiles of cognitive function that may help researchers understand why memory declines for some women and not others. This adds to the mounting evidence of the memory changes that can happen when menopause approaches and could lead to better guidance and treatment for patients experiencing memory issues.

Testing for some inflammatory proteins associated with the nervous and immune systems will help diagnose the earlier onset and progression of Alzheimer’s disease, according to a Rutgers study.

Researchers have recently carried out a study investigating the role of the X-chromosome on human brain anatomy. Their findings, published in a paper in Nature Neuroscience, highlight the key role of the X-chromosome in human neurodevelopment.

A new study explores a new non-dopamine reward circuitry in the brain.

An analysis of data from 1.5 million people has identified 579 locations in the genome associated with a predisposition to different behaviors and disorders related to self-regulation, including addiction and child behavioral problems.

Virtual reality helps to relieve pain and anxiety for children undergoing medical procedures, researchers report.

Scientists have long suspected that religiosity and spirituality could be mapped to specific brain circuits, but the location of those circuits remains unknown. Now, a new study using novel technology and the human connectome, a map of neural connections, has identified a brain circuit that seems to mediate that aspect of our personality.

Finally this week, researchers reveal the neurobiological basis of why we often find it more difficult to find the right words as we age.
