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.

Social Novelty Has a Special Place in the Brain

A specialized area of the mouse brain called the SuM specializes in detecting novel experiences. Within this brain area, responses to social novelty, or experiences related to unknown individuals, were segregated from those related to unfamiliar places, before being sent to areas of the brain associated with memory.

Adult-born neurons grow more than their infancy-born counterparts

Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.
