No You Dont Have a Reptilian Brain

The video debunks the myth of the reptilian brain, a concept popularized by Paul McClain's triune brain theory. This theory suggested that the human brain evolved in layers, with the basal ganglia (reptilian brain), limbic system (paleo-mammalian brain), and neocortex (neo-mammalian brain) each responsible for different functions. However, modern neuroscience shows that these brain regions do not work independently but rather in a coordinated manner. The video explains that the triune brain theory is outdated and that brain functions are distributed across various interconnected regions.

Explain why the term 'limbic system' is becoming less favored among neuroscientists.
