B. More recent studies have subdivided the premotor cortex of macaque monkeys into several more functional zones with different patterns of cortical and subcortical anatomical connections and different neuronal responses during various motor tasks. A similarly detailed functional subdivision of the parietal cortex has also been made (not illustrated). (M1, primary motor cortex; Pre-SMA, pre-supplementary motor area; PMd, dorsal premotor cortex; Pre-PMd, pre-dorsal premotor cortex; PMv, ventral premotor cortex.)
