Experiments mapping individual neurons in the sensorimotor cortex of mice show that sharp transitions in functional properties can define cortical regions.

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 is ...

The seemingly simple act of reaching for a cup of coffee requires a lot of effort from the brain. It has to plan a trajectory to the cup, control dozens of muscles, make adjustments based on feedback ...

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 used ...

Nicholas G. Hatsopoulos, Ph.D., Professor of Organismal Biology and Anatomy at the University of Chicago, has long been interested in space. Specifically, the physical space occupied by the brain.

In my first neuroscience course at Columbia University, I learned about the homunculus. This “little man” is depicted as an upside-down representation of the human body moving from toe to head in a ...

It has to plan a trajectory to the cup, control dozens of muscles, make adjustments based on feedback from the eyes and fingers, and maintain its focus on the goal: a tasty jolt of caffeine. And it ...

A new study has found high frequency propagating activity patterns in the motor cortex that contain details of upcoming movement -- information that could lead to the development of better ...
