Brain and Behavior part 2 Lecture Flashcards
Why is the surface of the cortex wrinkly?
to increase surface area
What are the four lobes of the cortex?
Frontal, Temporal, Parietal, Occipital
What is the frontal lobe responsible for?
planning, interpreting emotions, houses the motor cortex, and speech production
What lobe of the brain was damaged in Phineas Gage?
Frontal lobe
What happened to Phineas Gage as the result of his brain damage?
he was unable to acceptably express his emotions
What is the temporal lobe responsible for?
houses the primary auditory cortex, performs speech comprehension, and visual recognition
What lobe of the brain is damaged in someone with visual agnosia?
Temporal lobe
What is someone with visual agnosia unable to do?
inability to identify objects
What is the parietal lobe responsible for?
houses the somatosensory cortex, navigation, and math ability
What lobe of the brain is damaged in someone with hemispatial neglect?
Parietal lobe
. How do people with hemispatial neglect behave?
they ignore half the visual field and one side of all objects
What is the function of the occipital lobe?
houses the primary visual cortex. (used entirely for vision)
What lobe of the brain is damaged in someone with achromatopsia?
Occipital lobe
What would someone with achromatopsia be unable to do?
unable to see color (complete color blindness)
What is the name of the neural structure that allows the two hemispheres of the brain to communicate with one another?
corpus callosum
Which hemisphere of the brain controls and receives input from the right side of the body? Which hemisphere of the brain controls and receives input from the left side of the body?
- Left
2. Right
What functions of the brain are considered left hemisphere functions?
Speech production and speech comprehension
In what hemisphere and lobe of the brain is Broca’s area?
Left frontal lobe
What is Broca’s area responsible for?
speech production
In what hemisphere and lobe of the brain is Wernicke’s area?
Left temporal lobe
What is Wernicke’s area responsible for?
language comprehension
What functions of the brain are considered right hemisphere functions?
Face recognition, music, spatial abilities(mental rotation)
What is prosopagnosia?
the inability to identify faces
Which hemisphere of the brain is damaged in prosopagnosia?
Right hemisphere
What is the last name of the man who did the split brain studies?
Sperry
What part of the brain was severed in the split brain patients?
the corpus callosum
If a split brain patient held an orange in her left hand and a pencil in her right, what would she say if asked what she was holding?
Pencil
