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.

Physiological and behavioral analyses show that expression of cerebellar whisker learning can be mediated by increased simple spike activity, depending on LTP induction at parallel fiber to Purkinje cell synapses.
Cerebellar Purkinje cells represent movements via bidirectional linear changes in spike rate, and activity from single cells is sufficient to reconstruct kinematic changes during bouts of free whisking.
