A New Neural-Optic System Can Manipulate Memories

A new neuro-optics technique can manipulate memory consolidation in mouse models by hindering long-term potentiation. Researchers say eliminating local LTP in the hippocampus erased memories. The method could be used to isolate memory formation at the cellular level.

Fat Cells Found to Play a Central Role in Cognitive Decline and Neurodegeneration

A new study reveals how adipocytes, or fat cells, play a role in cognitive decline and increased neurodegeneration risks. Using genetically modified mouse models, researchers found oxidative stress through exposure to a Western diet increased the production of inflammatory cytokines confined to adipocytes and altered protein markers of memory and cognition in the hippocampus.
