Early research by Evarts demonstrated that movement force is related to:
A)an increased number of neurons firing in the primary motor cortex.
B)larger (that is, greater amplitude) action potentials in neurons in the premotor cortex.
C)an increase in the rate of firing in neurons in the premotor cortex.
D)an increase in the rate of firing in neurons in the primary motor cortex.
