Scientists tie specific brain circuit to sociability in mice

Social behavior in mouse models of autism spectrum disorder normalized when investigators triggered the release of a specific signaling substance, serotonin, in a single part of the animals' brains, according to a study from ...

Cocaine relapse is reversed with BDNF microinjections in the brain

Cocaine relapse was significantly reduced in a preclinical model when brain-derived neurotropic factor (BDNF) was applied to the nucleus accumbens deep in the brain immediately before cocaine-seeking behavior, report investigators ...

What makes aggressive mice so violent

Aggressive behavior and the motivation to act aggressively have distinct molecular bases, according to a study of male mice published in JNeurosci. This finding suggests the possibility of reducing aggression by targeting ...
