The limbic system, ... The archipallium or primitive ("reptilian") brain, comprising the structures of the brain stem – medulla, pons, cerebellum, mesencephalon ...
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 ...
A new region of the brain developed in mammals about 250 million years after the appearance of the hindbrain. This region is known as the paleomammalian brain, the major parts of which are the hippocampi and amygdalas, often referred to as the limbic system. The limbic system deals with more complex functions including emotional, sexual and ...
The old mammalian brain is found in a large percentage of mammals and is believed to have a strong intricate connection with the neocortex. [5] MacLeans idea of the ‘limbic system’ is based on the role the paleomammalian brain plays in brain function, where an individual's judgement of right and wrong stems from. [6]
Since the limbic system consists of evolutionary primitive structures which prevents its interpretation verbally, the visceral brain accounts for the visual, auditory, olfactory, and other external sensory inputs that are associated with emotions. [20] Recently, many studies have been done to analyze the anatomy and function of the Papez circuit.

In terms of the development of the nervous system in humans, the central nervous system is often classified based on the original three primitive brain vesicles: These primary vesicles form in the normal development of the neural tube of the embryo and initially include the prosencephalon, mesencephalon, and rhombencephalon, in rostral to caudal (from head to tail) orientation.
It constitutes a group of interconnecting brain structures that are involved in the functions of emotion processing, goal setting, motivation and self-control. The paralimbic cortex integrates external sensory information with internal emotional and motivational states, serving as an interface between higher-order cognition and basic emotional ...
