Motor Control Flashcards
1
Q
How is formation of a motor plan achieved?
A
Interactions between posterior parietal and premotor areas of the cerebral cortex
2
Q
Define kinematics
A
- Spatiotemporal form of the movement such as:
- Direction
- Amplitude
- Speed
- Path
3
Q
Define kinetics
A
Causal forces and muscle activity
4
Q
What is the function of the prefrontal cortex?
A
- Decisions
- Planning
- Initiative
- Motivation
- Conscience
- Moral sense
- Social skills
5
Q
What is the function of the parietal cortex? Distinguish specific areas
A
- Body representation
- Superior lobule
- Spatial representation
- Inferior lobule
6
Q
What is the function of the supplementary motor cortex?
A
- (medial area 6; basal ganglia)
- Internally generated/ guided movements, sequencing of actions
7
Q
What is the function of the premotor cortex?
A
- (lateral area 6; cerebellum)
- Sensory guidance of movement
8
Q
What is the function of the primary motor cortex?
A
- (precentral gyrus - area 4)
- Fine control of fingers (corticospinal tract) and face
- Specifies spatial characteristics of a movement based on sensory information from the posterior parietal cortex about the environment and about the position of the body in space
9
Q
What is the function of the lateral prefrontal cortex?
A
- Inhibitory control
- Executive function
- Task switching
- Working memory
10
Q
What is the function of the orbitofrontal prefrontal cortex?
A
- Motivated decision
- Emotional
- Autonomic responses:
- Taste
- Smell
- Reward (medial)
- Loss chasing behavior (lateral)
11
Q
Describe layer 1 of the cerebral cortex
A
- Layer 1 = molecular
- Axons and dendrites
