upper motor neurons part 1

Question 1

in the Divisions of the motor cortex in the macaque monkey brain, The lateral premotor and supplementary motor areas are involved in

Answer 1

selecting and organizing purposeful movements of the limbs and face

Question 2

in the Divisions of the motor cortex in the macaque monkey brain, The frontal eye fields do what?

Answer 2

organize voluntary gaze shifts

Question 3

in the Divisions of the motor cortex in the macaque monkey brain The cingulate motor areas are involved in?

Answer 3

the expression of emotional somatic behaviour

Question 4

Functions of the lateral premotor areas:
When a monkey is trained to reach in different directions depending on the nature of a visual cue ,what will the lateral premotor neurons will do and when?

Answer 4

the appropriately tuned lateral premotor neurons begin to fire at the appearance of the cue, well before the monkey receives a signal to actually make the movement.

*Rather than directly commanding the initiation of a movement, these neurons appear to encode the monkey’s intention to perform a particular movement; thus, they seem to be particularly involved in the selection of movements based on external events

Question 5

So-called “mirror motor neurons” where are they located and when do they fire?

Answer 5

So-called “mirror motor neurons” in the lateral premotor cortex fire when observing the behaviorally relevant actions of others.

Question 6

The mirror motor system may be involved in?

Answer 6

in encoding the intention to make the observed movement

Question 7

Functions of the medial premotor areas:

The medial premotor cortex seems specialized for ?

Answer 7

initiating movements specified by internal rather than external cues

Question 8

In contrast to lesions in the lateral premotor area, removal of the medial premotor area in a monkey reduces the

Answer 8

number of self-initiated or “spontaneous” movements the animal makes, whereas the ability to execute movements in response to external cues remains largely intact.

Question 9

The cingulate motor areas are involved in the

Answer 9

expression of emotional somatic behavior
