Motor cortex neural correlates of output kinematics and kinetics during isometric-force and arm-reaching tasks.
We recorded the activity of 132 proximal-arm-related neurons in caudal primary motor cortex (M1) of two monkeys while they generated either isometric forces against a rigid handle or arm movements with a heavy movable handle, in the same eight directions in a horizontal plane. The isometric forces increased in monotonic fashion in the direction of the force target. The forces exerted against th...
متن کاملEncoding in the motor cortex: was evarts right after all? Focus on "motor cortex neural correlates of output kinematics and kinetics during isometric-force and arm-reaching tasks".
The primary motor cortex is arguably the first cortical area to be functionally examined in the history of neuroscience. Beginning with the early electrical stimulation experiments by Fritsch and Hitzig (1960) in 1870 and then the first electrophysiological recordings in awake, behaving primates by Evarts in the 1960s (Evarts 1968), numerous experiments have been performed to try to understand ...

متن کاملActivity Does Not Reflect the Differential Time Course of Motor Output Kinetics during Arm-reaching and Isometric-force Tasks
Many single-neuron recording studies have examined the degree to which the activity of primary motor cortex (M1) neurons is related to the kinematics and kinetics of various motor tasks. This has not been explored as extensively for arm movement-related neurons in posterior parietal cortex area 5. We recorded the activity of 78 proximal-arm-related neurons in area 5 of two monkeys while they us...
