A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.
Activity in cortico-basal ganglia circuits of juvenile songbirds reflects evaluative signals necessary for comparing self-generated behavior to a goal representation during skill learning.
Motor performance benefits from rewarding contexts via a non-uniform reduction of response latencies and increase in feedback gains across the feedback loops involved in upper limb motor control.

Dorsomedial and dorsolateral striatal neural activity differ during early learning of action sequences but do not change with performance improvement across sessions, and become similar after extended training.
Inhibitory interneuron activity is dynamically modulated in new environments while individual interneurons show consistent levels of activity modulation across multiple environments, suggesting functional specialization of inhibitory subnetworks.
The 3R framework outlines three fundamental processes in motor learning and provides a novel perspective on understanding how we acquire, adapt, and retain complex motor skills.
