Brain & Behavior Part 2 Flashcards
Why is the surface of the cortex wrinkly?
To increase its surface area
What are the four lobes of the cortex?
Frontal, Temporal, Parietal, and Occipital
What is the frontal lobe responsible for?
Planning, interpreting emotions, speech production, and houses the motor cortex
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 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?
Cannot identify shapes
What is the parietal lobe responsible for?
Houses the somatosensory cortex (used for touch), 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?
See colors
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 he left side of the body?
Left hemisphere receives from right side of body
Right hemisphere receives from left side of body
What functions of the brain are considered left hemisphere functions?
Speech production and comprehension
In what hemisphere and lobe of the brain is Broca’s area?
Left frontal lobe
What is Broca’s are 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
W - Wernicke’s
W - What?
W - Word Salad
What functions of the brain are considered right hemisphere functions?
Face identification, processing music, and spatial abilities
What is prosopagnosia?
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?
Corpus callosum - allows two hemispheres to communicate with each other
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?
A pencil
Anything held in left hand was sent to right hemisphere (non-verbal) - patients could use item, but not name it
