The triune brain consists of the reptilian complex (basal ganglia), the paleomammalian complex (limbic system), and the neomammalian complex , viewed each as independently conscious, and as structures sequentially added to the forebrain in the course of evolution. According to the model, the basal ganglia are in charge of primal instincts, the ...
In the 1960s, Dr. MacLean enlarged his theory to address the human brain's overall structure and divided its evolution into three parts, an idea that he termed the triune brain. In addition to identifying the limbic system, he hypothesized a supposedly more primitive brain called the R-complex, related to reptiles, which controls basic ...
The Reptilian Brain was referred to by MacLean as the ‘R Complex’ or the primitive brain. [5] This is the oldest brain in the Triune Theory and anatomically is made up of the brain stem and the cerebellum. [10] In reptiles, both the brain stem and cerebellum dominate and are the control centres for basic function.

The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including humans. [1] It is named after Thomas Willis (1621–1675), an English physician. [2]
