Lecture 15-memory Flashcards
two major categories of long-term memory
declarative
implicit
declarative memory sub categories
episodic
semantic
implict memory subcategoris
procedural
priming
what is episodic memory for
memories related to emotions
ie your first kiss
what is semantic memory for
remebering facts
ie. Obama is the president now, April 1st is athena’s bday
what is procedural memory for
carrying out tasks like riding a bike, brushing your teeth
declarative v implict, which memory is in the subconscious
implicit memory
what is priming for
classical conditioning related to memory
i.e. when the light turns on you get shocked so now you know when you see the light to move your hand away
which parts of the brain does declarative memory use
telencephalon
- hippocampus
- medial temporal lobes
diencephalon
- anterior thalamic nuclei
- dorsomedial thalamic nuclei
- mammillary bodies of hypothalamus
two things that influence memory
emotion
motivation
procedural memory uses which brain parts?
striatum
motor cortex
cerebellum
priming uses which brain parts
emotional assocations- amygdala (fear)
conditioned reflexes- cerebellum (removing hand when light turns on to avoid getting shocked)
what is amnesia
memory loss/ability to learn due to physical or physiological trauma
what are the two types of amnesia
anterograde
retrograde
what is anterograde amnesia
inability to form new memories after trauma (consolidation)
what is retrograde amnesia
memory BEFORE trauma is affected…can form new memories though! (recall)
damage to what brain part causes problems in delayed non-match to sample tasks?
ant. + dorsomedial thalamic nuclei mammillary body (degeneration)
…basically the telencephalon
brain parts used for implicit memory
basal ganglia prefrontal cortex sensory association cortex cerebellum amygdala
which two brain structures does motor skill learning definitely require
basal ganglia
prefrontal cortex
which brain structure does conditioning require
amygdala/cerebellum
whic cortex is impt for working memory
prefrontal
which cortex impt for procedural memory
prefrontal and parietal (supplementary motor area)
which cortex impot for semantic memory (meaning of words)
wernickes area (temporal lobe)
brain part impt for remembering faces or objects
inferotemporal cortex
hebb’s postulate
neurons the fire together wire together
neurons that fire out of sync, lose their link
under what condition does LTP occur
post synapse must be depol’d the same time presynapse to firing an AP
