Answer 1

After deafferentation, monkeys were still able to make limb positioning movements, but aiming movements were not as accurate.

Step-by-step explanation:

After deafferentation, monkeys were still able to make limb positioning movements, but aiming movements were not as accurate. Deafferentation is the removal of afferent sensory input, which affects the monkey's ability to perceive and adjust their movements. While limb positioning movements rely more on proprioception and internal feedback, aiming movements require sensory input to accurately target a specific location.
