memory

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

Visual repesentation in sensory store

auditory representation

discovered the storage capacity and duration of sensory store

• 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

large storage capacity and contains long term neural changes that endure maibtance info Memory trace= Engram

engram

the process of information moving from STS to LTS underlies formation of memeory trace

MEmory traces that are under going consolidation and can be disturbed

Memeory traces have already undergon consolidation and can not be disturbed

Bring LTM back to conciousnous and awareness by transferring it to STS

Directly accessibl to consious recollection

Atobiography memeory of past events represents information temporally dated and can later be recollected

knowlege of the orld , organized information such as facts , vocab, concepts. Not temporally dated but can be recollected at any time

memory contained within learened skills or cognitive operations

Inablity to form new memories and learn the STS is in tact but information is not consolidated to the LTS

In formation prior to event that caused amnesia is lost but can be reteived with time

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

Inital dmage to the MTL followed by additional dmage to sensory association cortex intially anerograded amnesia followed by progressive rerograde amnsia

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

• experience of emotion is related to physiological functions
• emotions occur as a result of physiological reaction event

emotion and physiologically occur simuntalysly

low road amygdal

high road cerebal cortec then amygdala

• removal of amygdual cuses drmatic affects
• decrease in emtional reaction hypersexuality hypermetamorphism visual afnosua oral tendency

• ventromedial prfrontal cortec inhibits amygdala
• ohnias gage

sends excitory projection to Dipag and sites defensive aggression

excutes behavior during threat and autonomic responsed

generate rage dipag mus be activated

inhibits defensive responding
