Term
Brainstem
Definition
automatic survival functions
Term
medulla
Definition
heartbeat + breathing; part of brainstem
Term
pons
Definition
coordinates movement; part of brainstem
Term
reticular formation
Definition
arousal; part of brainstem
Term
thalamus
Definition
sensory switchboard
Term
cerebellum
Definition
coordinates muscular movement, helps process sensory informaiton
Term
limbic system
Definition
emotions, memory, and drives
Term
amygdala
Definition
responses of aggression +fear; part of limbic system
Term
hypothalamus
Definition
bodily maintenance functions, rewards, hormonal system; part of limbic system. stimulates pituitary gland to produce hormones
Term
cerebral cortex
Definition
thin surface layer of networked neurons covering the hemispheres. learning, thinking, complex information processing
Term
frontal lobe
Definition
speaking, muscle movements, planning, judgements
Term
parietal lobe
Definition
receiving sensory input for touch + body position
Term
occipital lobe
Definition
visual
Term
temporal lobe
Definition
auditory
Term
motor cortex
Definition
controls voluntary movement
Term
sensory cortex
Definition
body sensations
Term
reading aloud
Definition
visual cortex: register words as vis. stimuli
angular gyrus: transform into auditory codes
Wernicke's area: interpret codes, send to Broca's area
Broca's area: controls motor cortex to create pronounced words
Term
plasticity
Definition
ability of things to pick up other functions
Term
left hemisphere
Definition
verbal, speech in most people
Term
right hemisphere
Definition
visual, recognizing emotion
Term
glial cells (glia)
Definition
cells in the nervous system that support, nourish, and protect neurons
Term
association areas
Definition
areas of the cerebral cortex that are not involved in primary motor or sensory functions. they are involved in higher mental functions such as learning, remembering, thinking, and speaking.
Term
Broca's area
Definition
controls language expression, an area of the frontal lobe that directs the muscle movements involved in speech.
Term
Wernicke's area
Definition
controls language reception, a brain area involved in language comprehension and expression (usually in the left temporal lobe)
Term
aphasia
Definition
impairment of language, usually caused by left hemisphere damage iether to Broca's area(impairing speaking) or Wernicke's area(impairing understanding)
Term
corpus callosum
Definition
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
