This study identifies a movement-based dopamine signal in mice that acts as a value-free teaching signal for learning sound-action associations, working alongside reward prediction error.

The paper examines changes in serotonergic and dopaminergic neurons in the dorsal raphe nucleus of a Parkinson's disease mouse model following 6-OHDA injection.

This study shows that tonic activation of 4β2 nicotinic acetylcholine receptors on GABAergic interneurons primes feedforward inhibition, shaping striatal output timing and synaptic plasticity.
