Our brain is so advanced that it allowed us to develop culture, science, and technology. Nonetheless, our brain still preserves some primitive features, commonly known as the reptilian brain. The reptilian brain, or R-complex, belongs to the triune brain theory developed by the neuroscientist Paul MacLean. According to MacLean, ... Read more
