Association Cortex Flashcards
Layer 2
Goes to other cortical areas
Layer 3
Goes to other cortical areas on the opposite hemisphere
Layer 5
Goes to Subcortical structures
- Striatum
- superior colliculus
Layer 6
Goes to thalamus
Layer 4
gets input from the thalamus
Temporal association cortices
Visual forms, objects, textures
Auditory
Parietal association cortices
Attention- visuospatioal awareness
intention- visuomotor
somesthesis
Frontal association cortices
Spatial- object working memory
planning
withholding responses
Dorsal stream
Where/when pathway
to frontal lobe
-where to reach
-SWM- working memory of where object is
Ventral stream
Who/What pathway to frontal lobe -helps recognize what things are -grasp -guides other systems from frontal lobe
Agnosia
Impaired object recognition- temporal lobe damage
Achromatopsia
Impaired color recognition- temporal lobe damage
Prosopagnosia
Impaired face recognition- temporal lobe damage
Alexia
Impaired word recognition- temporal lobe damage
Wernicke’s aphasia
impaired word interpretation- temporal lobe damage
Broca’s aphasia
Impaired word usage- temporal lobe damage
Apraxia
object utilization/tool use deficits- temporal lobe damage
Parietal association area damage
Hemineglect- right side
usually dominate for spatial integration
Area 9
Planning
withholding action
why/not
Area 46
Spatial working memory
some object memory
where
Area 47/12
Verbal and object working memory
who/what
Facial recognition
Ventral
