The motor cortex makes up several regions of the neocortex involved in the planning, control and execution of voluntary movements. ... It has a highly defined somatotopic organisation.

Cortical organization shifts after sensory deprivation, but the reversibility of this reorganization has not been studied. Here, using functional magnetic resonance imaging (fMRI), we investigated ...

Arcaro et al. found evidence of somatotopic organization in these monkeys as early as 11 days old. Here's the key result. Each pair of egg-shaped regions represents data from one monkey, with 'M1' ...

Study: A somato-cognitive action network alternates with effector regions in motor cortex. Image Credit: r.classen/Shutterstock.com. Background. The human motor cortex was initially described as a ...

Propagating spatiotemporal activity patterns across macaque motor cortex carry kinematic information. Proceedings of the National Academy of Sciences , 2023; 120 (4) DOI: 10.1073/pnas.2212227120 ...

That map of the primary motor cortex — the motor homunculus — shows how this brain region is divided into sections assigned to each body part that can be controlled voluntarily (SN: 6/16/15).

The books show a model of the brain in which the motor cortex is solely controlling movement. ... So Dosenbach's team was puzzled when they began seeing hints of a very different organization.
