Sensing with the Motor Cortex
The primary motor cortex is a critical node in the network of brain regions responsible for voluntary motor behavior. It has been less appreciated, however, that the motor cortex exhibits sensory responses in a variety of modalities including vision and somatosensation. We review current work that emphasizes the heterogeneity in sensorimotor responses in the motor cortex and focus on its implic...
متن کاملThe motor cortex communicates with the kidney.
We used retrograde transneuronal transport of rabies virus from the rat kidney to identify the areas of the cerebral cortex that are potential sources of central commands for the neural regulation of this organ. Our results indicate that multiple motor and nonmotor areas of the cerebral cortex contain output neurons that indirectly influence kidney function. These cortical areas include the pri...
متن کاملMotor Cortex
M1 has been identified in several mammals, but most information comes from monkeys, cats, raccoons, rats, and humans. In each, five characteristics serve to define M1: (1) electrical stimulation there evokes movements with relatively low levels of electrical current, usually less than needed in other cortical fields; (2) it lacks a clearly identifiable internal granular layer, layer 4, and ther...
متن کاملForce and the motor cortex.
The relation between the activity of cells in the motor cortex and static force has been studied extensively. Most studies have concentrated on the relation to the magnitude of force; this relation is more or less monotonic. The slope of the relation, however, shows considerable variation among different studies and seems to be inversely associated with the range of forces over which the cell a...
متن کاملDecoding the Human Motor Cortex
A human being’s motor cortex becomes engaged when he or she performs specific motions. However, little is known about the relationship between the regions in the motor cortex. Neuroscience has not reached consensus over how motions for specific joints relate, or how engagement changes when a motion is performed more forcefully. We obtained fMRI BOLD scans of subjects’ motor cortices as they per...
