Question

Quizplus · Accepted Answer

Single-cell recording studies of the motor control of reaching movements have shown that neurons in the motor cortex are selectively active based on the direction in which a reaching movement is generated. This means that different neurons are activated depending on whether the arm is moving forward or backward, left or right, up or down, etc.
