Q

what happens in the case of a blink reflex

A

rods and cones are sensors and the muscles that control the eyelids are where the efferent neurons signal

Q

what happens when the tendon in the quad muscle is tapped

A

muscle is streched and muscle spindles respond to the stretch with an increase in AP
- this goes to the spine
- efferent signal back to muscle axons
- muscle contracts

Q

what causes the reflex/muscle contraction

A

the increase in the number of ap in afferent axons
causes motor neurons to fire ap and excite and contract stretched muscle

16
Q

when is the subject correct

A

slider in within 0.5 cm of 10.cm

17
Q

last 10 trails?

A

subject is told the excact distance they are from 10.cm

18
Q

last step

A

repeat 10 trails with no info

19
Q

what do we do with the results

A

graph a magnitude of error vs number of trails

20
Q

describe transfer of learning

A

a habit already exstablished has an influence on the relearning or performance of a second habit

21
Q

transfer of learning can be

A

positive or negative or both

22
Q

what is bilateral transfer of skill

A

transfer can occur if skill is learned in one hand then attempted in the other
- aka a transfer of skill from one side of the body to another (cross-transfer or bilateral trans)

23
Q

Mirror star trace apparatus

A
  • trail 1 use non perfered hand to try draw star clock wise in the mirror
  • always in contact with plate
    1-trial
24
Q

what other details of star procedure

A

must be done fast and we record errors
total score = error x2

25
what happens on the next step with the next hand
use preferred hand and do 10 trails
26
what happens at trail 12
do the non dominant hand again
