The triune brain is a model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s.
Triune mind, triune brain is a theoretical model developed by Canadian Buddhist scholar Suwanda H. J. Sugunasiri. It follows upon his clarification of the three terms used by the Buddha for consciousness, namely, Mano , Citta and Viññāṇa as can be seen in his work on the triune mind . [ 1 ]
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.
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 ...
This draws on the simplifying claims of the triune brain theory which are no longer considered accurate due to the many exceptions to this rule (see Triune brain § Status of the model). [1] The DVC provides primary control of subdiaphragmatic visceral organs, such as the digestive tract.
The neocortex includes the cortex and the cerebrum. It corresponds to the brain of primates and, specifically, the human species. Each of the three brains is connected by nerves to the other two, but each seems to operate as its own brain system with distinct capacities. (See illustration in Triune brain.)
The Triune Mind is a model of the mind of The Buddha's teaching, as conceptualized by Canadian Buddhist scholar Suwanda H. J. Sugunasiri. The theory was first published as "Triune Mind in Buddhism: A Textual Exploration", in the Canadian Journal of Buddhist Studies. Given the use of the term "triune", it is a model, which distinguishes the mind ...
Rapaille subscribes to the triune brain theory of Paul D. MacLean, which describes three distinct brains: the cortex, limbic, and reptilian. Beneath the cortex, the seat of logic and reason, is the limbic, which houses emotions. Camouflaged underneath those is Rapaille's theorized brain—the reptilian. [10]
