The archicortex is most prevalent in the [[primary olfactory cortex|olfactory cortex]] and the [[hippocampus]],<ref>{{cite journal|last1=Wills|first1=Tom J.|last2=Cacucci|first2=Francesca |last3=Burgess|first3=Neil|last4=O'Keefe|first4=John|title=Development of the Hippocampal Cognitive Map in Preweanling Rats|journal=Science|date=18 June 2010|volume=328|issue=5985 |pages=1573–1576|doi=10.1126/science.1188224|pmid=20558720|pmc=3543985|bibcode=2010Sci...328.1573W}}</ref> which are responsible for processing smells and forming memories, respectively.<ref name="Haberly 1990">{{cite book|last=Haberly|first=Lewis B|title=Cerebral Cortex|year=1990|isbn=978-1-4615-3824-0 |pages=137–166|edition=8B|chapter=Comparative Aspects of Olfactory Cortex|publisher=Springer }}</ref> Because olfaction is considered to be the phylogenetically oldest sensory modality,<ref>{{cite journal|last1=Albrecht|first1=J.|last2=Wiesmann|first2=M.|title=Das olfaktorische System des Menschen|journal=Der Nervenarzt|date=August 2006|volume=77|issue=8 |pages=931–939|doi=10.1007/s00115-006-2121-z|pmid=16871378}}</ref> and the [[limbic system]], of which the hippocampus is a part, is one of the oldest systems in the brain,<ref name=":0">{{cite journal |last1=Rajmohan|first1=V.|last2=Mohandas|first2=E.|title=The limbic system|journal=Indian Journal of Psychiatry|date=April–June 2007|volume=49|issue=2|pages=132–139 |doi=10.4103/0019-5545.33264|pmid=20711399|pmc=2917081 |doi-access=free }}</ref> it is likely that the archicortex was one of the first types of tissue to develop in primitive [[nervous system]]s.<ref name=":0" />
