The Theory of the Three Brains in Neuroscience


The brain can be categorized into three distinct parts, functioning as separate organs with unique cellular structures and roles. While these three parts of the brain maintain communication and exchange information, each one performs its own specialized function.


Neocortex: It is responsible for processing concrete information and data, serving as the rational aspect of the brain.


Limbic System: This part processes emotions and visceral sensations, playing a key role in emotional experiences.


Reptilian Brain: It is responsible for decision-making and tends to favor options that require minimal effort.
