Brains are like monkeys with supercomputers
This metaphor describes the brain as the combination of a monkey and a supercomputer. Subcortical structures are the monkey brain, while the neocortex is the supercomputer. The brain-monkey-supercomputer metaphor highlights different “attitudes” typically associated with cortical and subcortical structures. Subcortical ones are stereotypically primitive and savage, while the cortical structures are allegedly sophisticated and elegant.
