Role of Hippocampus and Amyglada in learning + neuroimaging help!

[cnguyen599]

Hi guys,

So can anyone tell me what I need to know about those two brain structures or any other important ones? I'm  also not sure the level of detail you would need to know about neuroimaging.

Thanks!

Hippocampus:
- it has an important role in the processing and storing declarative (episodic and semantic) information
-if damaged, the person won't be able to learn declarative information

Amygdala:
- it has a role in emotional learning and the fear response (classical conditioning)
- it strengthens a memory if it is associated with an emotional response
- if damaged, a person won't be able to feel the physiological effects of fear, even though they may know that the stimulus poses a threat and won't be able to be classically conditioned for an emotional response

Neuroimaging:
I suggest lightly going over the unit 3 neuroimaging stuff and focus on knowing which are functional and which are structural, and knowing the ones which provide functional information would be used for investigating changes in the brain during learning whereas structural ones can only show before and after shots

Hippocampus - Plays a role in spatial learned, affects memory to influence neuronal changes that result in LTP
                     - Consolidation of short term --> long term memories; specifically declarative
                     - In conjunction with Amygdala and Thalamus activates the fear response (ie fight/flight)

Amygdala - Responsible for emotional learning and fear conditioning
