anatomy/functions of speech programer

Question 1

The MSP transforms _______ ________ into a ______ ________ from which the motor programming can occur.

Answer 1

MSP = Motor speech programmer

The MSP transforms ABSTRACT PHONEMES into a NEURAL CODE

Question 2

What does the MSP neural code determine?

List the aspects of movement!

Answer 2

Specific muscle movements needed.
(6 aspects of movement)
Duration of movement
Amplitude of movement
Acceleration
Deceleration
Time to peak velocity
Timing of speech events

Question 3

Where are motor speech plans held? Can they be modified in this area? What does this result in?

Answer 3

They are held in a buffer area (in the brain). They can be modified, and this results in rapid speech.

Question 4

Where is the MSP held?

Answer 4

Left hemisphere - parietal-frontal and related subcortical circuits - IT ORGANISES LINGUISTIC INPUT!!!!!

Question 5

Where does the MSP gets its input/information from?

Answer 5

Perisylvian area (left)
temporoparietal cortex- insula(may not be involved with Apraxia)- basal ganglia - thalamus

**boadmans’s 6 – yes apraxia/// and aphasia too)

Question 6

Where exactly is the MSP??

Answer 6

• Premotor area (brocas, supplimental motor area, basal gang-putamen/caudate nucleus –> straiatum and cerebellar)
• Parietal lobe somatosensory cortex supramarginal gyrus
• insula?
• *Most common leison points: Brocas, Insula and Basal Gang!!!!!!
• *can happen on either side of the brain**

Question 7

With AOS, you also see:

Answer 7

Right sided weakness and spasticity, babinski, hyperactive reflexes, Limb Apraxia
