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?
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
