Childhood Lead Exposure Leads to Structural Changes in Middle-Aged Brains

Elevated levels of lead in the blood of children was associated with structural changes in the brain during mid-life. Those with higher levels of lead exposure as children had decreased hippocampal volume and structural deficits in white-matter integrity.

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.
