study of the brain (pg.98-108)

Question 1

medulla

Answer 1

base of the brainstem, controls automatic functions such as breathing.

Question 2

pons

Answer 2

it connects the brain with the spinal cord and also has a nerve system that controls unconscious processes such as sleep (when, more or less?)

Question 3

reticular formation

Answer 3

nerve network that travels through the brainstem into the thalamus and plays a role in arousal/control. (ex: obese people can have a problem with their reticular form. because they cannot control themselves when eating.)

Question 4

thalamus

Answer 4

brain’s sensory control center, on top of brainstem: like a switchboard that sends signals to the CNS from brain, from CNS to brain.

Question 5

EEG

Answer 5

measures electrical brain waves, high waves are associated with happiness/low waves-depression, flat line-braindead

Question 6

MEG

Answer 6

measures magnetic brain waves, ex. PTSD causes magnetic waves to be very low
petting pets can improve magnetic waves

Question 7

CT/CAT Scan

Answer 7

takes photographic x-rays of the brain, a look inside the brain without surgery

Question 8

PET scan

Answer 8

involves radioactive glucose dye which lights up the brain, colder colors are associated with depression while warmer colors are associated with happiness.

Question 9

MRI scan

Answer 9

both photographic and magnetic scan of the brain. deep, deep scan of the brain anatomy, can give details about why a person has a certain condition ex: schizophrenia

Question 10

fMRI

Answer 10

measures bloodflow in areas of the brain, shows brain function as well as structure.

Question 11

brainstem

Answer 11

oldest part of our brain, includes medulla pons reticular formation and thalamus
