1h Motor 1&2 Motor Cortex 2 Flashcards
1
Q
What side of body is controlled by Primary Motor Cortex relative to origin neuron in Area 4?
A
controls contralateral musculature
2
Q
Part of what tract originates in the Primary Motor Cortex?
A
1/2 of corticospinal tract
3
Q
Damage restricted to area 4 presents how?
A
CONTRALATERAL paresis
4
Q
What type of neurons are those of the corticospinal tract?
A
UMN
5
Q
What is the purpose population coding of UMNs?
A
a single UMN effects force of individual muscle, so populations that encode one area act together on LMNs to coordinate specific, precise movements
6
Q
What do the UMNs of the superior colliculus control?
A
UMNs for gaze control
