The sensorimotor network (SMN), also known as somatomotor network, is a large-scale brain network that primarily includes somatosensory (postcentral gyrus) and motor (precentral gyrus) regions and extends to the supplementary motor areas (SMA). [1] The auditory cortex may also be included, [2] as well as the visual cortex. [3] The SMN is activated during motor tasks, such as finger tapping, [4] indicating that the network readies the brain when performing and coordinating motor tasks. [1]
Dysfunction in the SMN has been implicated in various neuropsychiatric disorders.
In 2019, Uddin et al. proposed that pericentral network (PN) be used as a standard anatomical name for the network. [2]
