Centennial RIKEN Research


???This Spring we’ve put together a special centennial issue of RIKEN Research ???

Social novelty in the brain: haven’t I seen you someplace before?


Social novelty and contextual novelty are segregated in the SuM region of the hypothalamus and in projections to the hippocampus, allowing memories of meeting new people to be formed separately from memories of new places.

Astrocytes powered by norepinephrine during fear-memory formation


Norepinephrine released in the locus coeruleus during fear learning is accompanied by increased calcium and cAMP levels in nearby astrocytes.

Opto-OISI: imaging connections in the living brain


A new imaging technique called opto-OISI allows scientists to non-invasively visualize where specific neurons project in the living brain.
