Q

Thalamus

A

relays sensory and motor information from your body to your Cerebral Cortex

(you MUST (thalaMUST) use your thalamus, unless it’s MUSTY - smell)

Q

Somatosensory Cortex

A

processes sensory information
interprets touch, temperature, pain, preprioception (awareness of body position)

(Parietal Lobe: sensations)(in Cerebral Cortex)

17
Q

Motor Cortex

A
  • motor movements
  • planning, control, and execution of voluntary movements

(frontal lobe; in Cerebral Cortex)

18
Q

Damage to left hemisphere results in:

A

aphasia (damaged speech)

19
Q

Broca’s area

A

speech production (Broca - boca)

20
Q

Wernicke’s area

A

comprehension of speech

21
Q

Corpus Callosum

A

bundle of nerves that connect the two hemispheres (sometimes severed in patients with severe seizures – leads to “split-brain patients”)

22
Q

effect of split-brain procedures

A

patients could only process what they saw from their right eye (and it processed in the left hemisphere)

23
Q

Endocrine system

A

sends hormones throughout the body

24
Q

Pituitary gland

A

controlled by hypothalamus, releases growth hormones

25
Q

Adrenal gland

A

related to sympathetic nervous system – releases adrenaline

26
Q

EEG

A

brain activity – not specific

27
Q

XRAY

A

not useful, doesn’t show tissues

28
Q

CT / MRI

A

shows structures (tumors)

29
Q

PET

A

glucose shows brain activity (when in doubt PICK THIS ONE)

30
Q

fMRI

A

oxygen shows activity in real time

31
Q

lesion

A

destruction of the brain tissue
