TESTE DEIN WISSEN

Higher motor areas

Lösung anzeigen
TESTE DEIN WISSEN

 higher motor areas -> complexity and efficiency of behavior


-> monitored & modulated by 2 key motor systems:


  • the cerebellum
    • corrects errors in ongoing movements and learn new motor skills


  • the basal ganglia
    • gates motor commands and facilitates simple forms of learning

Apraxia

Lösung anzeigen
TESTE DEIN WISSEN

Apraxia 

= cant execute learned voluntary movements ( esp. complex sequences of movements) despite motivation & physical capability

TESTE DEIN WISSEN

Ideomotor apraxia

Lösung anzeigen
TESTE DEIN WISSEN

Ideomotor apraxia = 

  • inability voluntarily perform learned action when presented with the appropriate objects
  • or inability to imitate what someone else is doing
  • or inability to follow verbal instructions (e.g. waving goodbye, combing hair on command)

Ideational apraxia

TESTE DEIN WISSEN


= cant carry out sequential tasks involving tools or objects in the proper order (e.g. putting shoes on before putting on socks)

Verbal apraxia

TESTE DEIN WISSEN

Verbal apraxia = difficulty producing speech

Hierarchy of motor control 

(general levels)

Lösung anzeigen
TESTE DEIN WISSEN

1. highest level: motor programmes = sets of commands to initiate a sequence of movements

  • ballistic = do not strictly depend on incoming sensory information

 

2. Intermediate processing levels:

  •  translate motor programs into 
    • coordinated sequences of motor neuron activation
    • suppression that are responsible for muscle contraction & relaxation

 

3. Lowest level = elementary behavioral units ->  directly activate muscles

Motor Control Hierarchy 

6 parts


Lösung anzeigen
TESTE DEIN WISSEN

1.SMA,  Premotor, Prefrontal

  • Goals and planning of sequences of movement 


2. Motor cortex (M1)

  • partially involved in planning of movement
  • partially in activating specific groups of muscles 


3. Basal ganglia

  • Selecting and inhibiting motor actions
  • simple learning 


4. Cerebellum: Adjusting ongoing movements 


5. Brainstem

  • Relaying motor signals
  • Adjusting posture 


6. Spinal cord

  • direct activation of single muscle fibers 
  • reflexes

TESTE DEIN WISSEN

Posterior Parietal Cortex

-> computations for location based movement, grasping, reaching (scissors, cut, keys, open doors)

TESTE DEIN WISSEN


Premotor Cortex
Lösung anzeigen
TESTE DEIN WISSEN
  • Complex muscle movements
    • control over muscles in trunk & proximal muscles (close to trunk)


  • Learning sequences of motor actions
    • external cues (sensory info) is required
    • looking and listening to your guitar teacher when repeating a played sequence


  • Brocas region: directed to speech output
