Lecture 2: Brain Function Flashcards
What are the 3 major association areas?
1) Parieto-occipitotemporal
2) Prefrontal
3) Limbic
What happens when thalamic connections are cut?
Almost all function of the corresponding cortical areas are lost
What does the prefrontal association area do?
Receives preanalyzed sensory information needed for planning effective movements
Where does the output of the prefrontal association area pass through?
Caudate portion of basal ganglia
What does Broca’s association area do?
Provides circuitry for word formation
*Left brain dominant
What does the limbic association area do?
Concerned with behavior, emotions, & motivation
What does Wernicke’s area do?
Language comprehension, left brain dominant
What association areas meet at Wernicke’s area?
Somatic, visual, & auditory
What area of the cerebral cortex plays the greatest role for intelligence?
Wernicke’s area
T/F: Wernicke’s area and angular gyrus are more developed in left hemisphere in 75% of people.
False, in 95% of people
T/F: Broca’s area is more dominant in the left hemisphere?
True
T/F: Motor areas for controlling hands are dominant in the left hemisphere in 80% of people.
False, in 90% of people
What is the corpus callosum?
The major commissure between the two hemispheres
What 3 major things result from cutting the corpus callosum?
1) Blocking information from Wernicke’s area to nondominant motor cortex
2) Blocking of somatic & visual information from right hemisphere to Wernicke’s area
3) Results in 2 separate conscious portions of brain
What is declarative memory?
Memory of various details of an integrated thought
EX: Surroundings, time relationships, causes of experience
