1

parts of papez circuit involved in emotional processing?

cingulate cortex and the hypothalamus

2

Nociceptors exist as free nerve endings activated only when the stimulus is ___.

strong enough to cause damage. 

3

___ nociceptors have fast responses

thermal/mechanical

4

___ nociceptors are myelinated

thermal/mechanical

5

___ nociceptors are unmeylinated

polymodal

6

thermal/mechanical noiceptors are assocaited with ___ pain

sharp, prickling pain

7

polymodal nociceptors are assocaited with

with high intensity mechanical, chemical, hot, and cold stimuli.

8

Nociceptive specific neurons are found in___of the spinal cord

 Lamina 1 

9

nocipceptive specific neurons have ___ receptor fields

small

10

nocieptive specific neurons carry

only info about noceipcetion

11

. Wide dynamic range neurons (WDR) are found in ___ of the spinal cord

Lamina 5 

12

Wide dynamic range neurons  carry information

from both mechanoreceptors and noiceptors

13

Wide dynamic range neurons have ___ receptor fields

larger

14

. hyperalgesia is what happens when you have increased sensitivity to the ____.

surrounding unharmed region of a damaged area

15

with hyperalgesia Subsequent stimuli result in the 

enhanced sensation of pain 

16

referred pain is the result of a ____

 lack of nociceptive output neurons in the dorsal horn that are dedicated to visceral pain

17

dissociated sensory loss is when you have reduced sensation of epicritic sensation in the opposite side of the body from where you have ___.

reduced sensation of temperature and pain

18

Pain modulation can occur as the result of the descending pathway synapsing with 

an opiate containing interneuron

19

The opiate containing interneruon synapses with the ascending pathway in the dorsal horn releasing enkephalin that dampens 

both presynaptic and postsynaptic neurons

20

21

 first neurons that get binocular input are in the ___

striate cortex, not the lgn

22

X optic nerve ---> 

complete scotoma

23

X optic chiasm: 

bitemporal hemiopia. 

24

X optic tract on the right

lose  left visual field 

25

lesion of optic radiations

Quadrantanopia

26

leison of occipital cortex typically causes ___ hemianopias 

macular sparing

27

If Meyer's loop (temporal pathway) is lesioned, the Quadrantanopia is ____ superior

28

 if Baum's loop (parietal pathway) is lesioned in the optic radiations, the Quadrantanopia  is ___

inferior

29

lgn cells are binocular or monocular?

monocular.. they have functional segregation

30

The V2 thin stripes contain __ cells.

color
