Protein pileup affects social behavior through altered brain signaling

When a normal cellular cleanup process is disrupted, social behavior in mice is disrupted and they start behaving in ways that resemble human symptoms of autism spectrum disorder and schizophrenia.

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.
