11.1 - Cortical Association Areas Flashcards
What is the frontal lobe responsible for?
Higher intellect, personality, mood, social conduct, language (dominant hemisphere)
What is the parietal lobe responsible for?
Language, calculation (dominant hemisphere), visiospatial functions (non dominant hemisphere)
What is the temporal lobe responsible for?
Memory and language
What is the occipital lobe responsible for?
Vision
What would occur in damage to the temporal lobe?
recognition deficits e.g. agnosia and prosopagnosia
What would occur in damage to the temporal lobe?
attention deficits
What is the funciton of the limbic system?
rewards appropriate behaviours and punishes inappropriate behaviours
Which side is usually dominant in the brain? WHat does the dominant hemisphere do?
Normally left Language, maths, logic, motor skils
What does the non dominant hemisphre do?
emotion, music/arts, visiospatial, body awareness
Where is the input for language found in the brain
Wernickes area
Where is the output for language found in the brain?
Brocas area
What is the pathway for speaking a heard word?
Primary auditory area –> wernickes area –> Broca area –> motor cortex
What is the pathway for speaking a written word?
Primary visual area –> wernickes area –> Brocas area –> motor cortex
What happens if the wernickes area is damaged?
Wernickes aphasia. Disorder of comprehension, fluent but unintelligible speech. Less severe if non dominant side is damaged
What happens if the Brocas area is damaged?
brocas aphasia. Poorly constructed sentences and disjointed, but normal comprehension.
