Organisation of primary areas

Question 1

Principle of topographic organisation

Answer 1

Organised in such a way that adjacent neurons receive signals from portions of the body that lay close there as well.

Question 2

Proportion

Answer 2

Not to size of body but to amount of sensation/sensitivity

Question 3

Premotor areas

Answer 3

Devoted to motor control, directly in front of primary motor areas. Set up neural programs for producing movement. Sent to frontal lobe, to cerebellum, motor cortex etc.

Question 4

Prefrontal cortex

Answer 4

Involved in executive function, expanded most compared to other animals

Question 5

Track

Answer 5

Association areas in rear parts(temporal and parietal) sent output to prefrontal ass. areas, which combine info about internal environment and set op plans for action, sent it to motor cortex which sends it down.

Question 6

Hierarchy

Answer 6

Motivation and planning of movement : Limbic system and association cortex

Generation of programs for moving Basel ganglia/cerebel and premotor areas

Refinement of programs ; Motor nuclei and primary motor area

Maintenance of posture/execution motor nuclei of brainstem/spinal cor

Muscles
