Brain and Cognition 1 – Tutorial: Motor System
Answer Sheet
Tutorial aims:
- You know about the brain structures involved in motor control.
- You know about the processes involved in motor control.
- You know about disorders and plasticity related to motor control.
Preparation (before study group)
- Prepare all questions before the meeting.
- Please take with you to the study group meeting: the handbook, a printed version of the answer
sheets (available on blackboard) and headphones (to be able to listen to auditory information in the
movies).
Product
- A schematic drawing of the direct and indirect basal ganglia circuits.
- Answers to the questions in this tutorial.

, Question 1
Some body parts have a much larger representation in the motor homunculus than other body parts.
What does this reflect about the muscles (which are the final stage of movement) in those body parts?
Deze kunnen ook specifieker reageren. hoe meer bekwame bewegingen we kunnen met een bepaald
lichaamsdeel, hoe groter het hersengebied van dat lichaamdeel zal zijn.
Question 2
a. What type of information (sensory of motor) is carried by the corticospinal tracts?
motor
b. Complete the figure below by connecting the left motor cortex regions that control the arm (yellow)
and the trunk (blue) with the correct side of the spinal cord (left/right) and the correct body part(s).
c. What is the name of the part of the corticospinal tract that controls the arms and other extremities?
Lateral corticospinal tract
