Mesencephalic projections to the nucleus accumbens shell modulate value updating during probabilistic reversal learning

This study shows that optogenetic stimulation of VTA to NAcbS projections impairs reversal learning and increases exploitation bias in rats during probabilistic reversal learning.

5-HT 2A and 5-HT 2C receptor antagonism differentially modulates reinforcement learning and cognitive flexibility: behavioral and computational evidence

This study examines how 5-HT2A and 5-HT2C receptor antagonism affects reinforcement learning and cognitive flexibility in rats using behavioral and computational models.
