Association Cortices Flashcards
V4?
Colour perception
V1?
Ocular dominance columns
Fusiform face area?
Prosopagnosia, can’t recognise faces
Middle temporal destroyed?
Responsible for movement detection, so see-in still frames
Posterior association area?
Perception and language
Temporal association area
Emotion, memory
Prefrontal association area?
Executive function
Visual agnosia?
Inability to recognise and identify objects
Anosognosia?
Lack of ability to perceive the realities ones own condition
Prefrontal cortex responsible for?
Working memory, continuity of behavioural planning, anxiety for future
Apperceptive agnosia?
Failure in recognition because of visualising in different form
Associative agnosia?
Can’t associate meaning to object, man mistook wife for a hat
Broca’s area
Can’t produce language
Wernicke’s area?
Temporal lobe for comprehension
Aphasia?
Difficulty with language and speech
Wada procedure?
Injecting barbiturate in carotid artery, ask questions unable to produce language
Used to determine hemisphere dominant for speech
Brocas failure?
Nonfluent aphasia
Main multimodal association areas?
Posterior- perception language
Temporal- emotion memory
Prefrontal- executive functions
Visual agnosia?
Total or partial loss of ability to recognise objects or people
Prospagnosia?
Unable to recognise faces
Anosognosia?
Inability to recognise ones own illness
Apraxia?
Unable to perform learned movements on command even when the command is understood
Aphasia?
Disorders in communicating and using symbols
What is the prefrontal cortex important for?
Executive functions- long term planning and judgment, working memory, personality changes, continuity of behavioural planning
Apperception agnosia?
Failure in recognition due to deficits in early stages of perceptual processing
Associative agnosia?
Failure in recognition despite no deficit in perception
What does premotor cortex do?
Generate motor programs
