From Wikipedia, the free encyclopedia
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.
