Abstract

Preparatory tuning in premotor cortex relates most closely to the population movement-epoch response

Highlights

A common practice in systems neuroscience is to examine neural activity that precedes movement, in the hopes of better understanding the mechanisms that determined that movement
Both frameworks suppose that preparatory activity and movement activity are causally linked and closely related
What is preparatory activity tuned for? Second, how do activity patterns during the two epochs - preparatory and movement - relate to one another? We analyzed four datasets from three monkeys performing delayed-reach tasks. 550 single neurons were recorded from motor and premotor cortex, using single-electrode and array recording techniques
