1
Q

what are different ways to map the brain?

A

lesion method, EEG, PET scan, MRI, fMRI

2
Q

lesion method

A

damaging or removing sections of the brain

3
Q

electroencephalogram (EEG).

A

detect electrical activity of neurons in particular regions of brain

4
Q

Position Emission Tomography (PET) Scan

A

records biochemical changes in brain as they are happening in different locations

5
Q

MRI

A

Uses magnetic field to show picture of soft tissues

6
Q

functional Magnetic Resonance Imagining (fMRI)

A

measures relative activity of various brain area during tasks

7
Q

what is the structure of the brain?

A

the older brain structures, cerebral cortex, and limbic system

8
Q

brainstem

A

controls involuntary (i.e. heart beating) behaviors and primitive (breathing) behaviors under voluntary control

9
Q

what makes up the brainstem?

A

medulla and pons

10
Q

medulla

A

controls bodily functions that do not have to be consciously willed

11
Q

what is essential for survival?

A

medulla

12
Q

pons

A

regulates sleep and arousal: coordinates movements from left and right side of the body

13
Q

thalamus

A

relay station

directs incoming info from sense receptors to cerebral cortex

14
Q

reticular formation

A

controls arousal (sleep, wake); selective attention

15
Q

cerebellum

A

concerned primarily with coordination of movement

balance, muscle coordination

memory of simple skills, language, planning, reasoning

16
Q

limbic system

A

emotions, memory, additional control over instinctive behaviors

17
Q

amygdala

A

emotions (aggression/fear)

18
Q

hypothalamus

A

maintains internal balance

regulates eating, drinking, sexual behavior, body temp, “biological clock”

regulates endocrine activity

19
Q

hippocampus

A

“gateway to memory”

forms new memories about facts and events

20
Q

what is the cerebral cortex

A

higher forms of thinking

21
Q

what are the two parts of the cerebral cortex

A

two hemispheres (left and right)

22
Q

name the lobes on the hemispheres

A

occipital, parietal, temporal, frontal

23
Q

frontal lobe

A

at front of brain and planning, creative thinking, personality

contains motor cortex

24
Q

motor cortex

A

voluntary movement
