Single-cell dissection of Alzheimer's vascular changes across six brain regions

Your brain is powered by 400 miles of blood vessels that provide nutrients, clear out waste products, and form a tight protective barrier—the blood brain barrier—that controls which molecules can enter or exit. However, it has remained unclear how these brain vascular cells change between brain regions, or in Alzheimer's disease, at single-cell resolution.

Memories could be lost if two key brain regions fail to sync together, study finds

Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study led by the universities of Bristol and Heidelberg has found.
