The term derives from the idea that comparative neuroanatomists once believed that the forebrains of reptiles and birds were dominated by these structures. MacLean proposed that the reptilian complex was responsible for species-typical instinctual behaviours involved in aggression, dominance, territoriality, and ritual displays. [6]
The tissue that the human brain is made up of decomposes once the organism has died, so old brain tissue cannot be analysed, [9] however, due to the large percentage that the neomammalian brain takes up in the human brain, estimated to be 76%, [5] comparative anatomy shows that the Homo sapiens has a much larger cranial size than early primate ...

This concept is helpful to contain the reptiles and keep them from human dwellings. However, environmental fluctuations and predatorial attacks still occur in refuges. [33]
