The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain.
The Papez circuit / p eɪ p z /, [1] [2] [unreliable source?] [3] or medial limbic circuit, is a neural circuit for the control of emotional expression. In 1937, James Papez proposed that the circuit connecting the hypothalamus to the limbic lobe was the basis for emotional experiences.
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
All the forms of psychosurgery in use today (or used in recent years) target the limbic system, which involves structures such as the amygdala, hippocampus, certain thalamic and hypothalamic nuclei, prefrontal and orbitofrontal cortex, and cingulate gyrus—all connected by fibre pathways and thought to play a part in the regulation of emotion.

Limbic resonance is the idea that the capacity for sharing deep emotional states arises from the limbic system of the brain. [1] These states include the dopamine circuit-promoted feelings of empathic harmony, and the norepinephrine circuit-originated emotional states of fear, anxiety and anger.
The limbic system is the collective name for structures in the human brain involved in emotion, motivation, and emotional association with memory. The limbic system operates by influencing the endocrine system and the autonomic nervous system .
Hippocampus in the limbic system The hippocampus is one of the structures of the limbic lobe , first described by Broca in 1878, as the cortical areas that line the deep edge of the cortex. [ 14 ] The limbic lobe is the main component of the limbic system . [ 15 ]
Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the mammalian brain.
