Motor system and cortical area functions

Question 1

Integrated perception of motersystem

Answer 1

Visual input (external targets)
Somatosensory input (proprioceptive input; body image)
Eye and head movements (vestibular input)

Question 2

Reference frames

Answer 2

The posterior and parietal lobe play role as interface (connectionpoint) of sensory and motor networks using reference frames. Could be the street, you see a ball rolling and know it’s moving because the frame of reference is the street

Question 3

Egocentric reference frame

Answer 3

Retina, head and body (If you want to catch a ball that gets thrown at you, your mind needs to know where your hand is)

Question 4

Allocentric reference frame

Answer 4

Outside world

Question 5

Function of primary and secundary somatosensory cortex

Answer 5

Proprioception, tactile perception (pressure, stretch and vibration touch perception etc

Question 6

Primary and secundary visual cortex and parietal association areas

Answer 6

Visual perception (location, motion, where pathway)

Question 7

Premotor cortex, supplementary motor are and anterior cingulate cortex

Answer 7

Aciton schema, planning, selection, start and inhibition of motor behavior

Question 8

Primary motor cortex

Answer 8

Motor commands, regulation of muscle strengt
