6. What is the healthy response to galvanic vestibular stimulation?

  • balance response and small eye movements
  • large eye movements
  • lack of balance and eye movement

7. Which of these is not a chamber of the cochlea?

  • Stapedius scalae
  • Vestibuli scalae
  • Tympani scalae
  • Media scalae

8. What is the forward model?

  • where a efference copy is sent to the body anodised for prediction befor sensory feedback
  • waiting for sensory feedback before movement is planned and executed
  • planning ahead using sensory feedback

9. What causes voltage decay?

  • node of Ranvier
  • space constant and time constant
  • lack of myeline sheath
  • reduced firing

10. In what space does the body plan movement in?

  • end effector space
  • starting position
  • joint angle space
  • final position

11. How is a neural signal formed from photopigments?

  • Bleaching
  • breakdown
  • Reformation
  • excitability

12. What is the function of the Vestibulospinal tract?

  • Spacial orientation
  • Maintain postural stability when head moves
  • All of the above
  • Rotate eyes during head tilting

13. How do hair cells respond to sound?

  • they detect movement in otolith organs and semicircular canals and move to deflect cilia
  • they detect movement in otolith organs and semicircular canals and stop moving
  • they detect movement in ear drum and cochlea and move to deflect cilia

14. What does an EMG measure?

  • action potentials from a single motor unit
  • summation of nerve impulses along a muscle fibre
  • summation of action potentials from multiple motor units
  • a single action potential

15. What percentage of the brains neurone are found in the cerebellum?

  • 80%
  • 10%
  • 40%
  • 60%

16. Where does the basal ganglia output come from?

  • external globus pallidus and substantia nigra pars compacta
  • internal globus pallidus and substantia nigra pars compacta
  • internal globus pallidus and substantia nigra pars reticulata
  • external globus pallidus and substantia nigra pars reticulata

17. Where does the input for the cerebellum come from?

  • Climbing and mossy fibres
  • Basket cells
  • Purkinje and Golgi cells
  • fastigial nuclei

18. The transformation from x,y,z coordinates into joint angles is called what?

  • kinetics
  • inverse kinematics
  • forward kinematics
  • dynamics

19. What is the function of the vestibulocerebellum?

  • regulate balance, eye movement and coordinate head and eye movement
  • control posture, locomotion and eye movement
  • increase internal feedback and mental rehearsal of complex actions

20. Define pitch place theory

  • different parts of the cochlea respond to different frequencies meaning sound doesn't alway travel to the helicotrema
  • The cochlea only responds to certain frequencies
  • Different parts of the ear respond to different frequencies
