Serotonin Stabilizes Social Memories

Serotonin-producing neurons in the brainstem release serotonin throughout the brain during moments of novel social encounters. The release of serotonin stimulates neurons in the medial septum via a subtype of serotonin-sensitive receptor molecules. Blocking the release of this receptor molecule prevents the formation of new social memories.

Scientists Map Brain Circuit That Drives Activity in Fertile Females

Mouse study identifies specific neurons and a signaling pathway to regions of the hindbrain that mediate sexual reproductive activity and physical activity that appear to influence activity behaviors during ovulation. The findings may provide valuable insights into how estrogen loss during menopause disrupts this activity.

Protein From the Liver May Cause Alzheimer’s Disease in the Brain

Amyloid-beta proteins created in the liver are carried in the blood by lipoproteins to the brain. This results in neurodegeneration, brain atrophy, and inflammation, which are common features of Alzheimer's disease.
