Triune brain
Triune Brain
The Triune Brain (pronounced: /traɪˈjuːn breɪn/) is a model proposed by American physician and neuroscientist Paul D. MacLean to explain the functional structure of the human brain.
Etymology
The term "Triune" originates from the Latin word "triunus", meaning "three in one". It refers to the three distinct regions of the brain identified in MacLean's model: the reptilian complex, the limbic system, and the neocortex.
Definition
The Triune Brain model suggests that the human brain is divided into three sections, each responsible for different aspects of human behavior and cognition. These sections are:
- Reptilian Complex (Basal Ganglia): This is the most primitive part of the brain, responsible for survival instincts, dominance, territoriality, and aggression.
- Limbic System: This part of the brain is responsible for emotions, memories, and habits. It includes structures such as the amygdala, hippocampus, and hypothalamus.
- Neocortex: This is the most advanced part of the brain, responsible for cognitive functions such as reasoning, abstract thought, language, and consciousness.

Criticism
While the Triune Brain model has been influential in popular psychology and neuroscience, it has also been criticized for oversimplifying the complexity of the brain's structure and function. Modern neuroscientific research suggests that the brain's different regions are not as distinct as the Triune Brain model suggests, and that they work together in a highly integrated manner.
