Q

spatial memory

A

morris water maze; hippocampus as spatial map; london taxi drivers - hippocampus activates more when they answer to spatial questions

Q

late lesions of hippocampus (memory is affected, amnesia)

A

hippocampus is important in retaining memory after learning, and adjacent cortices may be responsible for memory extending farther back in time

Q

people with early hippocampal damage (learning is affected)

Q

fear conditioning happens where

22
Q

fear conditioning

A

damage to amygdala abolishes emotional memory but has little effect on other types of implicit or explicit memory

23
Q

procedural learning happens where

A

basal ganglia

24
Q

people with parkinsons disease may have problems with this type of learning

A

procedural learning

25
basal ganglia
striatum, globus pallidus, substantia nigra
26
reinforcement based teaching (trial and error) happens where
basal ganglia
27
what type of learning is less flexible
procedural learning
28
prefrontal cortex
it is more flexible, switching responses
29
long term potentiation
has to do with AMPA and NMDA
30
glutamate receptors '
AMPA and NMDA
31
NMDA receptors are blocked by what
magnesium positive ions
32
when do NMDA receptors open
after depolarization
33
When calcium and sodium enter through NMDA channels, it will release what protein
CREB
34
where does the protein CREB go
nucleus to alter genes (and gene expression)
35
how long can effects of protein CREB last
months or years
36
effects from protein CREB are modulated by what
brain-derived neurotrophic factor (BDNF)
37
repeated activation will lead to action potentials that back-propogate into dendrite and release what
BDNF
38
BDNF can increase what receptor
NMDA
39
anterograde amnesia
disruption of memory for experiences after the onset of amnesia
40
retrograde amnesia
disrupt memory for things learned prior to the event that initiated the amnesia
41
time-dependent retrograde amnesia
Injury severity determines how far back in time the amnesia extends. People usually start remembering with the passage of time and they only end up with an amnesia of a few seconds to minutes for events preceding the injury
42
Henry Molaison (HM)
they removed his hippocampus and part of the amygdala to end his epilepsy
43
what amnesia did HM suffer from
anterograde and retrograde amnesia
44
HM had severe impairment of what memory
episodic (couldn't describe any event that happened after the surgery)
45
people with amnesia are just as impaired in _____ as they are at describing the past
imagining the future
46
impairment in imagining the future and describing the past is a function of what
episodic memory
47
HM was better at ____ than ____ memory
implicit, explicit
48
news studies on low BDNF show a relation to what mental disorder
depression
49
HM had an intact _____, but as soon as he was distracted, the memory was gone within seconds
working memory
50
HM working memory leaving was due to
impaired storage of long-term memory (he was 27 for the rest of his life)
51
HM had intact _____ memory (videogames)
procedural
