Q

phieas cage

A

case study
he got a rod stuck in his head
started acting weird, theres a link between the brain and personality

2
Q

list the different types of brain tests and explain them

A

neuropsych test;
measures verbal and nonverbal behaviors of people with brain damage

EEG (electric reading);
studies brains electrical activity by putting electrodes on their scalp

destruction and stimulation techniques;
stimulate neurons and remove brain damage

brain imaging;
1. CT
xray of brain

  1. MRI
    magnetic resonance imaging, more detailed CT
  2. PET scan
    brain activity, functions of the brain, needs a dye injection some people dont like =>
  3. something
    same as pet scan except doesnt use the dye
3
Q

Hierarchy of the brain (check)

A

Hindbrain
midbrain
forebrain

4
Q

Hindbrain

A

the primitive level of the brain

medulla; heart rate, respiration, motor neurons

pons ; carries nerve impulses
sleep and arousal

cerebellum; motor movement, coordination, timing of movement (cats)

5
Q

brain stem

A

where the spinal cord meets the brain

6
Q

mindbrain

A

cluster of sensory and motor neurons
sleep wakefullness attention

reticular formation;

stimulation => attention
damage => coma

7
Q

forebrain

A

covered by cortex
reasoning, thinking
2 cerebral hemispheres (what are they)

8
Q

fissures

A

the line things that divide the brain, temporal, frontal…

9
Q

cerebral cortex

A
  • forebrain
  • motor cortex
  • 600 voluntary body movements

-somatic sensory;
receives sensory input that gives rise to our sensations

10
Q

left side of the brain

A
  • language hub
  • speech comprehension and production
  • happy emotions

brocca’s area;

  • speech formation
  • connections with motor cortex

wernikers area;
-speech understanding

damage;
loss of language

11
Q

association cortex

A
  • silent part of the brain
  • 75% of brain (3/4)
  • mental functions
  • puts info together for understanding and perception
  • silent part of the brain

problem;
agnosia
-the inability to identify familiar objects;
-the information sent to the visual cortex cannot be connected with info stored in areas of the brain

12
Q

hemispheric lateralization

A

corpus (left)

collum (right)

13
Q

right side of brain

A
  • spatial relations
  • mental imagery
  • artistic abilities
  • negative emotions

damage; difficulty recognizing faces

women have some of their language stored in the right side as well

14
Q

what happens of corpus collum is broken

A

if an object is flashed on the left side of the screen he cant say or write it but he can touch it and recognize it

if an object is flashed on the right side of the screen he cant recognize it, but he can say it

15
Q

brain plasticity

A

the neuron ability to change structures and functions
effects depend on the age and the extent of the damage

repairing damaged brain;
collateral spousing => the surviving neurons take over and the compensates

neurogenisis;
producion of new neurons in the nervous system (mainly in hippocampus)

stem cells (still working on it)

whats the difference between neurogenisis and stem cells though

16
Q

thalamus

A

located between brain stem and mindbrain

its like a switchboard
routes senses
organizes input from sensory organs and routes them to the appropriate brain area

abnormalities; schizo (confused world)

17
Q

hypothalamus

A
below thalamus 
part of limbic system 
motivation 
emotion
eating, sleeping, anger, sex drive 
connected to endocrine system 
pleasure and displeasure
18
Q

hippocampus

A

temporal lobe
forming and retrieving memories
limbic system

19
Q

amygdala

A
emotion center
fight/flight
aggression/fear
produces emotional responses 
connected with hippocampus (establishes emotional memories)
20
Q

limbic system

A

supports functions including emotion, behavior, motivation, long-term memory, and smell/flavor
