Introduction[edit | edit source]
The premotor cortex is a crucial part of the brain, which is believed to have direct control over the physical movements of voluntary muscles.[1] The PMC is about six times larger than the primary motor cortex[2]. The premotor cortex motor area lies anterior to the primary motor cortex.
The premotor cortex appears to play a role in orienting the body and readying the postural muscles for forthcoming movements. This appears to be the case as the premotor cortex mainly projects to the proximal musculature with efferent fibers from the premotor cortex serving motor neurons of the trunk and shoulders predominantly and it also receives inputs important for spatial orientation (from the posterior parietal cortex)[3]. It is especially active when motor routines are run in response to visual or somatic sensory cues, such as reaching for an object in full view or identifying an object out of sight by manipulation.
