Question

1. Although hippocampal damage is said to reduce episodic memory, it reduces memory for both emotional and neutral items similarly. Moreover, hippocampal activity is related to the encoding and retrieval of both emotional and neutral materials. How can we explain the ambiguity of why the hippocampus is not necessary for producing delayed emotion effects when compared to the amygdala?

Answer 1

There is this huge emotional relation between the episodic memories and the places. The hippocampus is generally responsible for the processing of long- term memories and emotional responses. And the amygdala is involved in the transforming of emotions activating the fight or flight response. In comparison to the clear body of brain imaging confirmation linking the amygdala to emotional memory procedures, neuroimaging findings have been more mixed with respect to the role of other MTL regions. In totality, the neural studies indicate that the hippocampus is not necessary for producing the delayed emotion effects.

- Emotional incidents are recalled much better than normal incidents, and this emotion trump-card becomes exceptionally pronounced over time. The time dependent effects of emotions smashes recollection preferably than the familiarity-based recognition, and they controlled recollection of the basic item- specific details preferably than contextual details. However, the amygdala, but not the hippocampus, is condemning in giving these effects. Time-dependent effects of these emotion have been assigned to an emotional merger process. Thus, the amygdala moderately smoothes the capacity of the emotional memories by other medial temporal lobe regions. Although, these effects can be better explained by an emotional binding account wherein the amygdala mediates the retrospection of item-emotion bindings that are usually unremembered more slowly than item-context bindings supported by the hippocampus.
