Nature - A study shows that loss of memory precision associated with systems consolidation can be explained by neurogenesis-dependent reorganization of engram circuitry within the hippocampus over...

Exclusive: British team exposed live cells to toxic proteins to gather rare insight into how dementia develops Scientists have used living human brain tissue to mimic the early stages of Alzheimer’s disease, the most common form of dementia, in a breakthrough that will accelerate the hunt for a cure. In a world first, a British team successfully exposed healthy brain tissue from living NHS patients to a toxic form of a protein linked to Alzheimer’s – taken from patients who died from the disease – to show how it damages connections between brain cells in real time.

Biologists now think there is a larger spectrum than just binary female and male

The mechanisms by which the brain replays neural activity sequences remain unknown. Recording from large ensembles of hippocampal place cells in freely behaving rats, we observed that replay content i...
