So we're going to be talking about the limbic system and trying to determine which element of the limbic system is most important for memory formation.
00:12
But first we have to ask ourselves, what is the limbic system? it's a few brain regions that when taken together are responsible for emotion but also have roles in learning, memory, and how we perceive smell.
00:32
There are three primary regions that are associated with the limbic system, and these include the olfarmic.
00:38
Bulbs, the hippocampus, and the amygdala.
00:54
Olfactory bulbs receive a lot of inputs from olfactory receptors, and are thus the brain region that is most responsible for the perception of smell.
01:08
The hippocampus is a brain region that takes information to create spatial and declarative memory.
01:24
Spatial memory is information having to do with the location of things or the directions to get to things, whereas declarative memory has to do with facts, memorizing a sequences of events, etc.
01:39
And the amygdala is responsible for understanding, remembering, and recognizing emotional situations.
02:04
Be sure when you're facing a question like this, that you're staying on task by restricting your information to things that you know are in the limbic system.
02:14
We could confuse ourselves even more by asking ourselves whether the pawns, or the epithalamus or the mesencephalon have anything to do with memory formation.
02:23
But none of these actually are part of the limbic system, so we're not relevant to the question here...
