19
Q

what type of pathway in the brain is used for short term memory

A

reverberating circuits

20
Q

how long does intermediate long term memory last for

A

hours to week

21
Q

what type of change in the brain is seen with intermediate long term memory

A

chemical adaptations in t presynaptic termial

22
Q

what is long term memory lenght

A

lifelong

23
Q

what chagnes in brain is seeen in long term memory

A

changes in sympatic connection with a stucualt change

24
Q

what is a reverbeating circit

A

short term memory, where a ciruclar cuitc, will be retain the information for a short time, and can be exitited by a stimulus

25
Q

what causes a revernating cuircuit to change into a intermide long term memory

A

depending on frequent the cirucit is acitivated

26
Q

amnesia

A

memory loss due to reverberation is disrupted

27
Q

what are teh types of amnesia

A

anterograde, and reterograde

28
Q

what is anterograde amnesia

A

cannot recall events that happen after an injury. ie. form new memories

29
Q

what is reterograde ameis

A

can’t remember events that happend before teh injury, or past events

30
Q

when does retrograde amnesia occur

A

when the thalams is damaged and the hippothalamus is spared

31
Q

role of thalamus

A

searching existing memory bank

32
Q

what type of moleucle is used for intermeida long term memory

A

ca

33
Q

how is ca effected in long term memories

A

increse ca into presymaptic termis, increas neruotramsion relase

34
Q

what are the stucual changes in long term memories

A

increases neural transimon reals on presymatic membarne
incras number of nerual trannon vessical stored and released
increase number of presynaptic termials

35
Q

what is the effect on long term member on the graded member postinal

A

incrase its amplitude

36
Q

what is long term potential

A

stenging of synape as reuslt of incras in ampltie in graded membrane potentl

37
Q

what are teh 2 types of long term memory

A

desclaritive or expliciti memory
proceduar/ reflextive/ implicit memory

38
Q

what is declarative or explicit memory

A

memory for events and wors and rules

39
Q

what stucure is controller for declartive memory

A

hippocampus

40
Q

what is proceudla memory

A

motor memeor, through repeptation e..g plyaing a sport

41
Q

what stucure is procedual memory associated with

A

cerebellum

42
Q

what is consolidaton

A

short term meory turning into long termm memory

43
Q

what are the stuucres of the frontal cortexs papez cirucit

A

hippocampus, mamillary bodies, anterior thalamus, cingulate gyrus

44
Q

funcito of papez cirucit

A

reverberating activy that conties tohought

45
Q

role of frontal cortex

A

acess wiethe ra memor is signicat in term of lyamtic syetm

46
Q

how to decide if a memory is still signifaicat

A

it is decied by forna ore, and rewriitn int papelx ciruicts
