Youn nan modèl yo pi byen li te ye pou konprann estrikti nan sèvo se devlopman evolisyonè nan modèl la nan sèvo. Sa a te devlope pa neuroscientist Pòl MacLean e li te vin trè enfliyan nan 1960 yo. Pandan ane sa yo depi, sepandan, plizyè eleman nan modèl sa a yo te oblije revize nan limyè de etid ki pi resan nerwanoatomik. Li toujou itil pou konprann fonksyon sèvo an tèm jeneral. Modèl orijinal MacLean a distenge twa sèvo diferan ki te parèt siksè pandan evolisyon:

One of the best known models for understanding brain structure is the evolutionary development of the brain model. This was developed by neuroscientist Paul MacLean and became very influential in the 1960s. Over the years since, however, several elements of this model have had to be revised in light of more recent neuroanatomical studies. It is still useful for understanding brain function in general terms. MacLean’s original model distinguished three different brains that appeared successively during evolution :
