Answer 7

true

Question 8

are both implicit and explicit memory part of long term memory?

Answer 8

yes

the repetitive loop of actions potential looping through the __________ __________ ___________ is what equals learning

Answer 10

hippocampal formation pathway

Question 11

what is a flashbulb memory?

Answer 11

vivid and long-lasting memory of a surprising or shocking event

Question 12

if something were to go wrong in the ______________ you would have some sort of amnesia

Answer 12

hippocampus

Question 13

what are the two types of memory that sometimes work interchangeably in explicit memory?

Answer 13

semantic and episodic

Question 14

what are AMPA receptors?

Answer 14

chemical receptors, connect to Na+ ion channels

Question 15

t or f: when we recall a memory it is common that we change it

Answer 15

true

Question 16

what does Ach, 5-HT have to to do with memory?

Answer 16

improves memory process

Question 17

process of __________ _________:

• action potential enters through entorhinal cortex
• goes through perforant pathway and dentate dyrus
• then forms synapse, forming another pathway (mossy fiber pathway)
• goes through CA3 and fornix
• makes connections in limbic system and cortex around it and synapses with other neurons
• schaffer collateral pathway formed and axons synapse with neurons in CA1 area
• exit through entorhinal cortex

Answer 17

hippocampal formation

Question 18

what is anterograde amnesia?

Answer 18

difficulty making new memories after a traumatic event (to hippocampus)

Question 19

what are neurofibrillary tangles?

Answer 19

something has changed within the neurons themselves

Question 20

what does NE/Epi have to do with memory?

Answer 20

improves emotional memories (short-term) through the amygdala

a memory of an event that evoked a strong emotional response

Question 34

what do the amygdala and hippocampus have to do with memory?

Answer 34
