- Prefrontal to ventral tegmental area dynamics drive contingency degradation
Researchers have made a discovery about prefrontal circuits in the rodent brain that permit flexibility to stop learned behaviours. This discovery provides a mechanistic understanding of interactions with core subcortical reward systems. The study was published online in Nature on May 6, 2026.
- Dopaminergic mechanisms of dynamical social specialization
A 2026 Nature study reveals mice develop stable, specialized social roles during foraging tasks, with dopaminergic activity in the ventral tegmental area driving sex-specific specialization patterns. The research highlights neural mechanisms underlying social role differentiation in animal groups.
