Existence of somatotopic organization of finger in the primary motor cortex (M1) hand area has not been confirmed yet. The purpose of this study was to investigate fine scale finger somatotopy in ...

The main objective of this research is to investigate how the somatotopic representation of motor cortex changes along no-use of affected facial muscles. We use Bell's palsy patients who has ...

A series of companion studies supported the findings in this manuscript. An integrated transcriptomic and epigenomic atlas of mouse primary motor cortex cell types, Yao et al., 2020 Evolution of ...

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 ...

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 ...

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).

Notably, motor cortex (MC) activity exhibits quasi-oscillatory dynamics during arm reaching (Churchland et al., 2012). More generally, the temporal structure can depend on the movement type (Suresh et ...

Somatotopic organization of hyperdirect pathway fibers projecting from the primary motor cortex trunk, arm, hand, face, and tongue area. The tracts are displayed on axial and coronal T1-weighted ...
