This study shows ketamine reduces habenula activity during aversive learning in humans, supporting preclinical findings on its antidepressant mechanisms.

This study shows how increased synaptic histamine affects hippocampal dynamics and learning by using a causal probe and analyzing neurocomputational strategies.

This study uses a selective serotonin releasing agent to examine how increased synaptic serotonin affects decision-making in aversive contexts, finding reduced sensitivity to aversive outcomes and enhanced impulse control.

The paper investigates how affective memories influence value-based decision-making using reinforcement learning models and shows a positive bias in recall preferences.
