1

Modes:

the physical forms of stimuli carrying information

2

unimodal:

one mode of information. For example, light. unimodal association could be integration of direction and intensity of light

3

unimodal cortex-

area adjacent to primary cortex that recieves input from only that primary cortex

4

multimodal cortex-

area where we integrate multiple senses

5

Primary visual cortex is broca's area 17 and it's unimodal broca's areas are

18 and 19

6

primary somatosensory cortex is broca's areas 3, 1, 2 and it's unimodal broca's areas are

5 and 7

7

primary auditory cortex unimodal association areas are brocas areas:

41, 42

8

primary motor cortex brocas area:
unimodal association cortex brocas areas:

4
6, 8

9

limbic lobe is composed of what parts?

cingulate gyrus, hippocampus, parahippocampal gyrus, hypothalamus, mamillary bodies, and fornix (connects hippocampus with mamillary bodies)

10

the neocortex is organized in 2 ways:

laminar and regional

11

what is unique about motor cortex lamina?

heterotypical agranular with large layer V containing Betz cells

12

what is unique about sensory cortex lamina?

heterotypical granular cortex with large layer IV containing granule cells

13

granule cells recieve afferent input from the

thalamus

14

what is unique about association cortex lamina?

homotypical (all layers about the same size)

15

recite the broadmann's areas associated with this region:
parietal-occipital

5-7, 18-19

16

recite the broadmann's areas associated with this region:
occipital-temporal

37, 20-21

17

recite the broadmann's areas associated with this region:
speech areas

22, 39-40, 42, 44-45

18

recite the broadmann's areas associated with this region:
prefrontal areas

9-11, 46-47

19

parieto-temporal association cortex function
parietal:
temporal:

-mediates spatial relationships and attention
-object and face recognition

20

the ____ part of the parieto-temporal association cortex is in the non dominant hemisphere, while the _____ is bilateral

-parietal
-temporal

21

the parieto-temporal-frontal association cortex is in the dominant/non dominant hemisphere?

dominant

22

the parieto-temporal-frontal association cortex is involved in:

mediating language comprehension (wernicke; parietal/temporal), language expression (broca; frontal), and reading and writing

23

the prefrontal association cortex mediates-

planning, judgement, and intellect, leading to goal directed behaviors

24

the prefrontal association cortex has significant connections with ______ areas, which integrate _________

-limbic
-cognition with emotions

25

limbic cortex mediates:

emotions and memory

26

where do inputs to an association cortex come from?

thalamus (Dorsomedial, lateral posterior, and pulvinar), primary and secondary sensory cortical regions (of ipsilateral hemisphere), association cortex of contralateral hemisphere, brainstem, and motor and premotor cortex

27

where do outputs from an association cortex go?

thalamnic nuclei, premotor-->motor, caudate/putamen--> VA/VL--> motor/premotor, cerebellum, and other primary and secondary sensory cortical regions

28

where do outputs from an association cortex go?

thalamnic nuclei, premotor-->motor, caudate/putamen--> VA/VL--> motor/premotor, cerebellum, and other primary and secondary sensory cortical regions

29

ventral intraparietal cortex is highly associative for aspects of ________ and _______

somatosensory and visual information

30

multimodal responses-

one cell can respond to multiple stimuli
