Document Summary
There are two main categories of memory: declarative (explicit) Mediated by the hippo, medial temporal lobe, diencephalon: nondeclarative (implicit) Includes riding a bike or swimming once you learn this skill you never forget even if you do not practice for a long time. Emotional responses amygdala, what you associate with certain emotions. Skeletal musculature cerebellum, how you move through space. The hippo is located deep within the brain (folds of the temporal lobe) and is composed of three main regions: All three regions are connected in some way. Info enters through both unimodal and polymodal association areas and goes to the parahippo and perirhinal cortices in parallel streams entorhinal cortex. The ec then projects to 4 other regions: dg, ca3, ca1 and the subiculum. Ec dg ca3 via mossy fibers ca1 via schaffer collaterals subiculum and back out to the ec. This is the (cid:271)asi(cid:272) (cid:862)(cid:373)e(cid:373)or(cid:455) loop(cid:863) (cid:272)o(cid:374)sisti(cid:374)g of 5 regio(cid:374)s. Lesions of the r hipp affect spatial memory.
