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.

Researchers have studied what part of the brain controls speech, and now we know much more. The cerebrum, more specifically, organs within the cerebrum such as the Broca's area, Wernicke's area ...

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.

The finding involves a strip of brain tissue called the primary motor cortex. As its name suggests, this area is considered the main source of signals that control voluntary movements.

Body parts that humans have fine control over, such as our fingers and tongue, appear larger-than-life on the map, because they take up a disproportionate amount of the primary motor cortex.

Most studies of brain functional networks have been based on fMRI scans of people at rest, but many parts of the brain or cortex are not fully active in the absence of external stimulation.

New Brain Network Discovery Rewrites The Textbook On The Motor Cortex The mind and body appear to be connected in ways that no one previously understood.

The neocortical primary somatosensory area (S1) consists of a map of the body surface. The cortical area devoted to different regions, such as parts of the face or hands, reflects their functional ...

For nearly a century, scientists have known that different parts of the human brain's cortex control different body movements. This fundamental discovery dates to the 1930s, when neurosurgeons ...

Since the 1930s, the so-called homunculus map has shown how different parts of the brain's motor cortex may control movement to different parts of the body. But it may be missing an important ...

A long-reigning map (left) of the primary motor cortex, or motor homunculus, linked sections to specific body parts to explain the connection between the brain and voluntary movement.

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 ...
