Association cortex Flashcards
1
Q
Temporal association cortices
A
- Visual forms, objects, texture
- Auditory prosody, syntax
- Polymodal/heteromodal–aud/vis/somat
2
Q
Frontal association cortices
A
- Spatial, object working memory
- Planning
- Withholding responses
3
Q
Parietal association cortices
A
- Visuospatial awareness (attention)
- Visuomotor transformations (intention)
- Somesthesis
4
Q
Primary thalamus projection in the neocortex
A
-Layer 4
5
Q
Dorsal stream
A
- Where/when pathway
- Occipital, parietal, frontal lobe
- Involved in attention to a stimulus, intention, and planning
6
Q
Ventral stream
A
- Who/what pathway
- Temporal lobe
- Show “face cells” that are selectively activated
- Watch and learn system–mirror neuron system
7
Q
Agnosia
A
- Impaired object recognition
- Damage of ventral stream/temporal region
8
Q
Achromatopsia
A
- Impaired color recognition
- Damage of ventral stream/temporal region
9
Q
Prosopagnosia
A
- Impaired face recognition
- Damage of ventral stream/temporal region
10
Q
Alexia
A
- Impaired word recognition
- Damage of ventral stream/temporal region
11
Q
Blindsight
A
- Patient doesn’t know that they can see
- Primary visual areas damaged but temporal areas spared
12
Q
Hemineglect
A
- Inattention and impaired spatial accuracy
- Damage in the dorsal stream
13
Q
Prefrontal association areas
A
- Retain info about what and where things are
- Oculomotor delayed response–neural substrate of working memory
14
Q
Area 9
A
-Planning, monitoring sequential actions or words, withholding action
15
Q
Area 46
A
-Spatial working memory, as well as some object memory
