Research provides important insight on the brain-body connection

A study conducted by University of Arkansas researchers reveals that neurons in the motor cortex of the brain exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls ...

How the brain makes rapid, fine adjustments in motor activity

Short-term motor learning appears not to require physical change in the brain Brain's premotor cortex may use a 'neural scratch pad' to calculate fine adjustments Brain can try different things in simulation without 'screwing ...

Engineers decode conversations in brain's motor cortex

How does your brain talk with your arm? The body doesn't use English, or any other spoken language. Biomedical engineers are developing methods for decoding the conversation, by analyzing electrical patterns in the motor ...

Brain has natural noise-cancelling circuit

To ensure that a mouse hears the sounds of an approaching cat better than it hears the sounds its own footsteps make, the mouse's brain has a built-in noise-cancelling circuit.

Increased corticomotor excitability ID'd in restless legs

(HealthDay)—For patients with restless leg syndrome (RLS), the primary motor cortex (M1) exhibits hyperexcitability, which is associated with disease severity, according to a study published recently in Sleep Medicine.

Motor control—how the brain responds to unexpected situations

Scientists have demonstrated that the motor cortex is necessary for the execution of corrective movements in response to unexpected changes of sensory input, but not when the same movements are executed spontaneously. Signatures ...
