new information that contains faithful representation of sensory input obtained from each sense.. that enters through our senses Only lasts for 500ms new information is either passed to our STM or lost
Iconnic memeory
Visual repesentation in sensory store
echoic memory
auditory representation
Sperling partial report technique
discovered the storage capacity and duration of sensory store
Short term memory
locous control with in the system attends to information and governs retrival from LTM ..It is a consious mental activity Information can be stored ther indefnitly long as reharsal occurs
in STS info is either forgoten or transferred to LTM
Long Term memory (storage)
large storage capacity and contains long term neural changes that endure maibtance info Memory trace= Engram
Memory trace
engram
Consolidation
the process of information moving from STS to LTS underlies formation of memeory trace
Labile LTM
MEmory traces that are under going consolidation and can be disturbed
Consolidation LTM
Memeory traces have already undergon consolidation and can not be disturbed
Retreval
Bring LTM back to conciousnous and awareness by transferring it to STS
Declarotive memory
Directly accessibl to consious recollection
Episodic memory
Atobiography memeory of past events represents information temporally dated and can later be recollected
semantic memory
knowlege of the orld , organized information such as facts , vocab, concepts. Not temporally dated but can be recollected at any time
procedual memeory
memory contained within learened skills or cognitive operations
Anterograded Amnisia
Inablity to form new memories and learn the STS is in tact but information is not consolidated to the LTS
Retrograde amnesia
In formation prior to event that caused amnesia is lost but can be reteived with time
Medial temporal lobe and cause of damage
The amygdala and hippocampus area
damage to the area causes antrograded amnesia of semantic and episodal memeories and slight retrograde amnesia with evens closley related to trama that caused amnesia
Alzheimers
Inital dmage to the MTL followed by additional dmage to sensory association cortex intially anerograded amnesia followed by progressive rerograde amnsia
glutmate
nutotranssmiter released in the induction of LTP binds to AMPA a excitory receptor responsible for brains rapid movement
Also binds to NMDA receptors in post synaptic membrane
Ca++ chanels do not open until series of ESPS remove Mg++ then Ca++ enters postsynaptic memc membran
James Lange theory
experience of emotion is related to physiological functions
emotions occur as a result of physiological reaction event
cannon bard theory (thalmic therory)
emotion and physiologically occur simuntalysly
le doux dual model
low road amygdal
high road cerebal cortec then amygdala
kuver bucy
removal of amygdual cuses drmatic affects
decrease in emtional reaction hypersexuality hypermetamorphism visual afnosua oral tendency
vmpfc
ventromedial prfrontal cortec inhibits amygdala
ohnias gage
dmVhm
sends excitory projection to Dipag and sites defensive aggression
dipag
excutes behavior during threat and autonomic responsed
