what is the function of the hippocampus in memory?
- temporary storage of declarative memories
- consolidation and encoding of explicit memories
what happens if the hippocampus malfunctions?
- unable to store new declarative memories
- H.M and Clive Wearing
- anterograde amnesia
what is the function of the amygdala in memory?
- emotional implicit memories
- flashbulb memories
what happens if the amygdala malfunctions?
- eliminates fear
what is the function of the cerebellum in memory?
implicit procedural memories
what is the function of the cerebral cortex in memory?
- pariatal- STM
- frontal- retrieval

- permanent memory storage
what happens if the cerebral cortex malfunctions?
permanent LTM loss, amnesia, retrograde
what are flashbulb memories?
very vivid, detailed memories of traumatic or emotional events.
how accurate are flashbulb memories?
despite high confidence in them, they are not very accurate
how does a flashbulb memory occur?
adrenaline is released as a neurohormone as a result of the fight or flight response being activated by the emotional situation. Adrenaline is also released in the brain. it is released within 30 seconds of the event. adranaline triggers the amygdala (medial temporal lobe) which increases function and triggers the hippocampus. the hippocampus and the amygdala together create stronger, more permanent emotional memories that are hard to erase
what are classically conditioned memories?
conditioned responses, often associated with fear eg. phobias
