In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Adult neurogenesis, already appreciated for its role in learning and memory, also participates in mental health and possibly even attention, new research suggests.
Glial cells were once considered neurons’ supporting actors, but new methods and model organisms are revealing their true importance in brain function.
From determining structures to figuring out functions, brain-mapping scientists are applying new technologies to understand the hub of the central nervous system.
