Serotonin Affects Behavior and Motivation

A new study reveals how activating the brain's serotonin center affects behavior and motivation in awake mice. Using optogenetics and high-field MRI, researchers found that stimulating serotonin neurons in the dorsal raphe nucleus (DRN) activates the cerebral cortex and basal ganglia, critical areas for cognitive functions.

Serotonin Drop Linked to Memory Decline in Early Alzheimer’s Progression

Researchers discovered a potential link between lower levels of serotonin, the "happiness" chemical, and mild cognitive impairment (MCI), which could advance our understanding of Alzheimer's Disease (AD). Their study indicates that individuals with MCI have significantly reduced serotonin transporter levels, a factor that might contribute to memory problems and potentially AD.
