How do you select which action to perform? 1. Draw the pathway in the basal ganglia that helps select the motor movement to perform.
Homework Answers
The action which is to be performed is maintained by the structures found in the brain. One such structure is basal ganglia. These structures are found deep within the cerebral hemispheres. Basal ganglia are interconnected with other brain structures such as the cerebral cortex, thalamus, and brainstem. The primary function of basal ganglia is associated with motor movement. It works in association with the cortex and allows controlling the motor movements. Any sort of damage to the basal ganglia leads to altered functioning. Such a condition is called Parkinsonism. In this condition, the individual fails to coordinate his/her movements, speech and cognition skills are also impaired, etc. Its pathway is drawn below.

2. Explain the differences between motor learning and motor control within the field of motor behavior. Motor learning is an internal state that is relatively permanent. Practice is required in order for motor learning to occur. Practice is repetition errors become consistent, fewer or smaller then learned. Before practice you need to have a goal setting, then instructions, after instructions you need to have demonstrations. During practice...
