How can we improve memory with emotional stimuli?

More emotionally arousing situations improve memory retention

1 of 6

Explain how extinction is not 'unlearning'.

As it is new learning of a CS with no US, and the new memory is inhibitory of the original CS-US memory, leading to a decrease in memory expression. The original memory still exists.

2 of 6

Describe the neural basis before extinction

Sensory info of shock arrives at the amygdala via the hippocampus, which contextualises the event, and the amygdala produces fear response, and fear memory produces this response whenever the context is congruent with this fear memory

3 of 6

Describe the neural basis after extinction

The IL mPFC stores the new memory of the context without the shock, and inhibits amygdala output to reduce the response. Outside of the extinction context, the amygdala output is not inhibited

What do we call the process of retrieving a memory from LTM (inactive) to the STM (active)?

Reactivation or destabilisation depending on what we do with the memory

5 of 6

How could re-consolidation impair or strengthen memory?

As when we bring it into an active state, we are able to modify it
