The basal ganglia (BG) contribute to reinforcement learning (RL) and decision-making, but
unlike artificial RL agents, it relies on complex circuitry and dynamic dopamine modulation …

The in vivo responses of dorsal raphe nucleus (DRN) serotonin neurons to emotionally-
salient stimuli are a puzzle. Existing theories centred on reward, surprise, or uncertainty …

Abstract Machine learning research has achieved large performance gains on a wide range
of tasks by expanding the learning target from mean rewards to entire probability …

Limits on information processing capacity impose limits on task performance. We show that
male and female mice achieve performance on a perceptual decision task that is near …

What does serotonin do? Just as the diffuse axonal arbours of midbrain serotonin neurons
touch nearly every corner of the forebrain, so too is this ancient neuromodulator involved in …
