Front 1

HM had what removed

Back 1

from BOTH sides

Front 2

HM can retain

Back 2

normal amount of info, if not distracted
slightly higher IQ

Front 3

ischemia

Back 3

reduced blood to brain, can produce similar symptoms of HM

Back 4

dorsomedial thalamus, both mammilaries

Front 5

NA suffers

Back 5

KC & memory

Back 9

loss episodic, semantic OK

deficits due to cortical damage, particluarly FRONTAL PARIETAL

Front 10

sensitization

Back 10

if there is a sudden increase in strength in stim that has not been habituated, subsequent reactions exaggerated

Front 11

three reasons for loss of memory

Back 11

never formed
deteriorates as consequence of time
may be irretrievable from injury

Front 12

iconic memory

Back 12

a few seconds at most

Front 13

two alternative, forced choice procedure

Back 13

present 1000
correct recognize 90%, even with 10,000 to discriminate from

Front 14

delay non match to sample

Back 14

medial temporal lobe impairs declarative memory

Front 15

animal research has shown that _ is unimportant in declarative memories

Back 15

amygdala

Front 16

kesner's experiemnts limited to

Back 16

short term memory

Front 17

test phase of kesner rat study

Back 17

food in arm that the rats just entered

Front 18

lesions in X impair 8 arm maze task, test phase

Back 18

hippocampus

Front 19

response task of kesner

Back 19

rienforce if turns SAME direction, memory of previous response

Front 20

lesions of X impair kesner's response task

Back 20

cuadate nucleus

Front 21

kesner sensory task & brain region

Back 21

must go to novel object, nock over object not yet seen

lesions to extrastriate visual ctx

Front 22

kesner tests reveal X of three brain regions

Back 22

Back 23

important for nondeclarative memory

Front 24

spatial stimuli

Front 25

left hippocampus and parahippocampal gyrus

Back 25

verbal stimuli

Front 26

encoding episodic info depends on X portion of medial temporal

Back 26

Front 27

retrieval of episodic info depends on X portion of medial temporal

Back 27

Front 28

when listening to autobiographical passage, increase activation of

Back 28

right frontal and temporal lobesstu

Front 29

study of Drosophilia demonstrated X type learning

Back 29

nonassociative

Front 30

dorsolateral prefrontal system

Back 30

required for object perminance

Front 31

conditioning does / does not modify the simple arc reflex

Back 31

does change

Front 32

cell assembly

Back 32

laterations in pattern of firing can encode meories

each neurons in ensemble may participate to greater or lesser extent

signature of activity pattern for each stored item

Front 33

hebbian synapses, & continual firing

Back 33

if close enough to continue to increase firing, then METABOLIC or STRUCTURAL changes in one or both take place to increase EFFICACY

Front 34

fire together wire together

Back 34

simultaneous firing
conditional learning

Front 35

hebb & dual trace hypothesis

Back 35

experience sets up activaiton of neural circuit that reverberates
hold for short period
if activation sufficient, activity in circuit causes a stable change
stable change corresponds to memory trace

Front 36

in EC IC, EC animals exhibited

Back 36

increase number of dendritic spines, particularly on basal dendrites

Front 37

filopodia

Back 37

electrical activity of neurons promotes these dendritic extensions

Front 38

how do filopodia form dendritic spine?

Back 38

contact axon, activation of AMPA or NMDA receptors stabilizes

Front 39

main inputs to hippocampal formation come from

Back 39

entohinal ctx

Front 40

main input to hippocamap formation come from entohinal ctx via

Back 40

perforant pathway

Front 41

drugs thata inhibit CaM kinase interfere with..

Back 41
