In motor cortex, the laminar organization of cortical circuits has not been resolved, although their input-output operations are crucial for motor control.

As first author Evan Gordon, Assistant Professor, explains, “the organization of the motor cortex did not correspond well with the “homunculus” described by Wilder Penfield back in the 1930s, which is ...

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 ...

Scientists’ understanding of the organization of the human motor cortex – the parts of the brain that allow us to plan, execute, and control movements – hasn’t changed much since the ...

Future studies could investigate whether similar modular principles apply to other areas of the cortex involved in cognition and sensory processing. Reference: Tamura K, Bech P, Mizuno H, Veaute L, ...

Movement is a complex process governed by a network of neuronal circuits spread across multiple regions of the nervous system ...

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 ...

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.

Textbooks show the primary motor cortex as a continuous ribbon with sections devoted to specific muscle groups, from tongue to toe. That view dates back to the 1930s, when Canadian neurosurgeon ...
