medulla
vital functions (circulating blood, breathing muscle tone, reflexes)
pons
sleep + arousal + dreams
linked to spinal cord, unconscious movement and process
cerebellum
(little brain)
movement, balance, muscle memory
reticular formation
relay message to body

thalamus
sensory switch board (relay system)
all sensory info (except smell) must pass to get to the cerebral cortex

agnosia
recognize things
occipital lobe
visual cortex
pituitary gland
master gland, directed by hypothalamus
regulates growth & metabolism
adrenal gland
stress hormones
thyroid glands

EEG
monitors the electrical activity of brain over time
sleep studies
(function)
PET Scan
radioactive glucose to see functioning of the brain OR where is activity occurring in the brain?
(function)
fMRI
functional neuroimaging procedure using MRI tech that measures brain activity by detecting associated changes in blood flow
(function)
lesioning
destroying piece of brain and observing effects (animals)
(structure)
CT scan
uses x-rays to create a 3D image
diagnosis of therapy
bone structure / soft tissue
cross-sectional image
(structure)
MRI
magnets / radiowaves to see structure of soft tissue
