This study investigates how Purkinje cells in the cerebellum control tongue movements in marmosets by suppressing their activity during specific phases of movement.

The paper investigates how the inferior olive informs Purkinje cells about sensory events and movement plans in marmosets, revealing two distinct groups with different spike patterns related to movement control.

The paper shows that increased effort cost of harvest in marmosets leads to longer work duration, reduced movement vigor, and pupil constriction, suggesting a coordinated neural response to optimize fitness.

The paper shows that complex spikes in Purkinje cells alter saccadic eye movements by pulling them toward the visual space preferred by the olivary input to those cells.

This study shows that cerebellar Purkinje cells use spike synchronization, not firing rates, to signal when to stop saccadic eye movements in marmosets.

This study shows that correcting movement errors during sensorimotor adaptation carries an implicit cost, affecting learning efficiency based on error cost modulation.

P-sort is an open-source software that improves spike detection and attribution in cerebellar Purkinje cells by merging and splitting clusters based on statistical relationships between simple and complex spikes.

The paper describes behavioral training and electrophysiological recording protocols in marmosets to increase trial numbers and target cerebellar Purkinje cells.

The paper tests if reward prediction error (RPE) modulates saccade vigor by inducing RPE events before saccade onset and measuring their effect on saccade velocity and reaction time.
