- Papez circuit: the hypothalamus, anterior thalamus, cingulate cortex, hippocampus and fornix

- Limbic model of emotion: this model includes the papez circuit, as well as the amygdala and several other brain regions 

Medial Brain regions involved in emotion

Studies investigating different brain regions associated with emotion concluded that there is no singular brain region associated with a specific emotion. Rather, each emotion has different patterns of activation across several different brain regions.

Brain Regions Associated with Emotions

- Brain self-stimulation: the process in which animals work to provide electrical stimulation to certain areas of the brain because it is a rewarding experience.

- Experiments in the 1950's found that rats will readily pull a lever to receive electrical stimulation in the septum

- Brain self-stimulation can also be seen in humans. Patients receiving electrical stimulation in the septum have been known to feel pleasure and warmth. 

Electrical Brain Stimulation & the Effects on Emotion

- Electrical stimulation of the brain, brain lesions, and neural circuitry affect emotion.

Neural circuitry of violence and aggression

Theories of emotion are frameworks developed to explain how the various components of emotion, such as physiological arousal, psychological appraisal, and subjective experience, interact with one another to produce an emotional state.
