Cognitive Processes Flashcards
Lateral geniculate
- input
- output
- retina
- primary visual cortex
Medial geniculate
- input
- output
- cochlea
- primary auditory cortex
Lateral posterior nucleus
- input
- output
- association cortex, anterior geniculate, retina
- parietal and visual cortex, anterior cingulate, striatum
Apraxia
inability to complete a task
Agnoia
deficits is recognition (not sensation)
Prosopagnosia
inability to recognize faces
Visual agnosia
inability to recognize an object by sight
unimodal visual association cortex
Astereognosia
inability to recognize an object by touch alone
Which area of the brain matures first?
sensorimotor
Which hemisphere of the brain is usually language-dominant?
left
What is the function of the parietal association cortex on the dominant side?
skilled movements
right-left handed dominance
What is the function of the parietal association cortex on the non-dominant side?
attention
What deficit occurs when there is damage to the dominant parietal association cortex?
motor apraxia
What deficit occurs when there is damage to the non-dominant parietal association cortex?
spacial neglect
What is the function of the superior temporal association cortex?
language
social attention
What is the function of the inferior temporal association cortex?
recognition
Deficits in recognition
agnosia
What is associative agnosia?
can identify but not name objects
What is the area of the brain damaged with an associative agnosia?
posterior parietal cortex
What is the order in which areas of the brain mature?
- sensorimotor areas
- unimodal association areas
- prefrontal cortex
Which area of the brain is first to degenerate in Alzheimer’s dementia?
prefrontal cortex
