David A. Leopold is in the Section on Cognitive Neurophysiology and Imaging, National Institute of Mental Health, Bethseda, Maryland 20814, USA. In the 1930s, the neurosurgeon Wilder Penfield ...

Scientists have discovered that signals in the motor cortex act like a series of clutches when it comes to moving, and that these signals can be disrupted to slow the brain's initiation of movement.

Neurons in the brain's motor cortex previously thought of as active mainly during hand and arm movements also light up during speech in a way that is similar to patterns of brain activity linked to ...

The motor cortex homunculus is getting a makeover. New research has essentially redrawn the motor cortex and constitutes one of the most substantial shifts in our topographical knowledge of a sensory ...

Researchers have discovered that the dorsal premotor cortex serves a 'meta-learning' function, overseeing and regulating physical movements. Once believed to be limited to movement planning, this ...

The neocortex makes up the greater area of the cerebral cortex. It is divided into different regions (the frontal, parietal, occipital, and temporal lobes) by the bone structure of the skull above it.

Hundreds of neuroscientists from across the globe, including researchers from the Tolias Lab at Baylor College of Medicine, have built a “parts list” of the motor cortex, mapping in exquisite detail ...

Scientists found evidence of two interleaved systems, which may help explain the connection between what's going on in our bodies and what's going on in brain areas involved in thoughts and emotions.

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 ...
