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

“A part of the cerebrum, the part of the frontal lobes called the primary motor cortex or precentral gyrus helps with planning and execution of voluntary movement,” he says.

The frontal lobe controls motor skills & controls thinking, organizing & problem-solving. Understand its functions, disorders & other insights.

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 ...

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.

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

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.

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 ...

Movement planning elicits finger-specific activity in primary somatosensory cortex that is strongly correlated to the finger-specific activity elicited during movement execution.

While researchers have discovered numerous cell types in the brain, this atlas of all cell types in one area -- the primary motor cortex -- is the first comprehensive list and a starting point for ...

Background and Purpose: Cortical beta oscillations are reported to serve as robust measures of the integrity of the human motor system. Their alterations after stroke, such as reduced movement-related ...

Primary motor cortex (M1) undergoes protracted development in mammals, functioning initially as a sensory structure. Throughout the first postnatal week in rats, M1 is strongly activated by ...
