The motor cortex executes responses based on sensory choices, but it is unknown whether it also impacts response selection. Here, Pape and Siegel show that motor cortex activity present before ...

Textbooks show the primary motor cortex as a continuous ribbon with sections devoted to specific muscle groups, from tongue to toe.

Another brain region, called the premotor cortex, is known to have a role in planning movements, but the areas found by Gordon and Dosenbach's team are woven into the primary motor cortex itself.

Nico Dosenbach says one day they noticed something odd in the primary motor cortex, an area that controls muscles. NICO DOSENBACH: It just didn't make sense if the textbook was right.

Their paper, published in Nature Neuroscience, shows that the involvement of the motor cortex in motor sequence execution depends on the extent to which a given task requires flexibility.

The cerebral cortex, also known as gray matter, is your brain’s outermost layer and is located above the cerebrum. Learn more about its vital functions.

The primary motor cortex on the left side of the brain controls movement of the right side of the body, and vice-versa, the right motor cortex controls movement of the left side of the body.

A new brain imaging study has found that people who regularly use cannabis show reduced spontaneous activity in a key motor ...

Within the brain’s frontal lobe lies the primary motor cortex, a sliver of neurons that coordinates movement. Beginning in the 1930s, scientists developed a map of this brain region called a ...

The classical view of how the human brain controls voluntary movement might not tell the whole story. That map of the primary motor cortex — the motor homunculus — shows how this brain region ...
