Flashcards in Cog. Neuro Deck (29):
1

released at the synapse

neurotransmitters

2

proposed neuron doctrine

Cajal

3

limitation to nerve net theory

technology limitation

4

firing of specialized neuron that responds to a specific object

specificity coding

5

MRI long version

magnetic resonance imaging

6

MRI does what

determines structure of brain

7

these neurons only respond to specific stimuli

feature detector

8

principle that says we don't have direct contact with stimuli, but instead our brain creates reps of the world

principle of neural representation

9

patient damages one area causing a to be messed up but B to be ok.

double dissociation

10

define neuron doctrine

individual neurons transmit signals... they are not continuous with others... there's a gap

11

small gap between a neuron's axon terminal and the dendrite

synapse

12

charge when there's no signal being transmitted

-70 millivolts

13

action potential

nerve impulse sent down axon

14

stimuli to cats causes specific neuron to fire

hubel and wiesel

15

charles gross found what

monkey simple/complex stimuli

16

neurons in temporal lobe respond to what?

complex stimuli

17

neurons in visual cortex respond to what

simple stimuli

18

sensory coding

how neurons represent various characteristics of the environment

19

populatio coding

a large number of neurons to rep a particular object

20

sparse coding

small number fired/object

21

cerebral cortex

cognitive function

22

occiptal lobe

vision

23

temporal lobe

hearing

24

parietal

sensory

25

frontal lobe

thinking/problem solving

26

broca's area

damage to left frontal lobe, only say one word

27

wernicke's area

temporal lobe damage, fluent in speech but incoherent

28

prosopagnosia

can't recognize faces

29

fMRI

measure metabolic changes correlated with neural activity
