Question 4

Association Cortex:

what layers do inputs come into?

Answer 4

come in at all levels, except inputs
from the thalamus only go to layer 4
(the granular layer)

Question 10

achromatopsia - impaired ___ recognition

Answer 10

color

Question 11

• agnosia - impaired object recognition
• achromatopsia - impaired color recognition
• prosopagnosia - impaired face recognition
• alexia - impaired word recognition
• receptive aphasia - impaired word interpretation. Input problem, ex. Wernicke’s • expressive aphasia - impaired word usage. Output problem, ex. Broca’s
• apraxia - object utilization / tool use deficits (

a lesion where would cause all of these?

Answer 11

temporal association areas/ventral stream

Question 12

apraxia – deficits with

Answer 12

object utilization / tool use deficits

(impaired motor planning / ability to
carry out learned purposeful movements)

Question 13

The ___ does “Metacognition.”

Answer 13

Prefrontal Cortex

Question 14

___ is the meaningful selection of behavior to achieve desirable outcomes and avoid undesirable ones

Answer 14

metacognition

Question 15

metacognition invovles what 3 things

Answer 15

integrating sensory info + pausing motor responses + monitoring outcomes

Question 16

define association cortex

Answer 16

everything that is not a primary motor, primary sensory, or premotor area

Question 17

association areas receives inputs from multiple areas and tie them together in some manner that was not possible in the

Answer 17

intiial sensory areas

generate more meaningful repsonses

Question 18

all neocortical association areas have at least ___ layers

Answer 18

5, most have 6

Question 19

dorsal is the where stream goes from v1 to

Answer 19

occipital to parietal

Question 20

damage to __ pathway can cause –

inability to describe context of object, cant
use visuospatial cues
hemispatial neglect

Answer 20

dorsal pathway

Question 21

___ projection: to develop a memory for what
the object is recognized by the ventral stream

Answer 21

ventral prefrontal cortex

Question 22

what happens if primary visual areas are damaged but the temporal association areas are spared

Answer 22

blindsight

pt doesnt know they can see

e.g. show them stimuli.. say they cant see then ask them to just name whatever comes to mind and they end up saying what they could see
