<p><b>New page</b></p><div>'''Archicortex''' is a part of the [[cerebral cortex]], primarily involved in functions related to [[memory]] and [[spatial navigation]]. It is one of the three types of cortex in the [[mammalian brain]], the other two being the [[neocortex]] and the [[paleocortex]]. <br />
<br />
==Structure==<br />
The archicortex is characterized by a three-layered structure, unlike the six-layered neocortex. It is found in the [[hippocampus]], a region deep within the brain that plays a crucial role in memory formation. The three layers of the archicortex, from outermost to innermost, are the molecular layer, the pyramidal layer, and the polymorphic layer.<br />

==Function==<br />
The archicortex is involved in various cognitive functions, primarily related to memory and spatial navigation. It is a part of the [[limbic system]], which is associated with emotions, long-term memory, and olfaction. The archicortex's role in memory is particularly significant in the formation of episodic memories, which are memories of specific events and experiences.<br />
<br />
==Clinical significance==<br />
Damage to the archicortex, particularly in the hippocampus, can lead to memory disorders such as [[Alzheimer's disease]] and [[amnesia]]. In Alzheimer's disease, the hippocampus is one of the first regions to be affected, leading to memory loss and disorientation.<br />
