The premotor cortex of the monkey
Webb3 feb. 2024 · While the animals performed the task, we recorded 863 single neurons (286 neurons from monkey A and 577 neurons from monkey P) in two regions of the ventrolateral PFC (the ventral pre-arcuate region, VPA, and inside the inferior arcuate sulcus, ASi) and the adjacent rostroventral premotor cortex (PMrv, part of area 6rv) . WebbMonkey Premotor Cortex Machiko Ohbayashi,* Kenichi Ohki,† Yasushi Miyashita* To plan a serial order behavior, we hold serial sensory information in our minds and convert it to a movement program. We trained monkeys to memorize a sequence of positional cues and to reproduce it by making saccades in either the original or reverse order.

While the animal was reaching for different objects, Rizolatti and his team registered the activity of individual neurons in this area using recording electrodes that they inserted into the premotor cortex.
