Research by Evarts found that the firing rate of neurons in the monkey motor cortex:
A) increased as the amount of force required to make a wrist movement increased.
B) decreased as the amount of force required to make a wrist movement increased.
C) was not related to the amount of force required to generate wrist movement.
D) varied with the monkey's emotional state.

Evarts' research found that the firing rate of neurons in the monkey motor cortex increased as the amount of force required to make a wrist movement increased. This relationship between firing rate and force suggests that the motor cortex is involved in generating and controlling movement.
