caption_attribution_description: English: Graziano, MSA(2008) The Intelligent Movement Machine. Oxford University Press. Figure originally by Graziano, M.S.A. Some commonly accepted divisions of the cortical motor system of the monkey. PMDr = Dorsal premotor cortex, rostral division, also sometimes called Field 7 (F7). PMDc = Dorsal premotor cortex, caudal division, also sometimes called Field 2 (F2). PMVr = Ventral premotor cortex, rostral division, also sometimes called Field 5 (F5). PMVc = Ventral premotor cortex, caudal division, also sometimes called Field 4 (F4). SMA = supplementary motor area. SEF = supplementary eye field, a part of SMA. Pre-SMA = pre-supplementary motor area. FEF = frontal eye field.
context_page_description: The premotor cortex is an area of motor cortex lying within the frontal lobe of the brain just anterior to the primary motor cortex. It occupies part of Brodmann's area 6. It has been studied mainly in primates, including monkeys and humans. The functions of the premotor cortex are diverse and not fully understood. It projects directly to the spinal cord and therefore may play a role in the direct control of behavior, with a relative emphasis on the trunk muscles of the body. It may also play a role in planning movement, in the spatial guidance of movement, in the sensory guidance of movement, in understanding the actions of others, and in using abstract rules to perform specific tasks. Different subregions of the premotor cortex have different properties and presumably emphasize different functions. Nerve signals generated in the premotor cortex cause much more complex patterns of movement than the discrete patterns generated in the primary motor cortex.
