There are two major physioligical theories of emotions. these are the theory, which holds that emotions are the perception of certain internal bodily changes, and the theory, which argues that the thalamus in the lower brain is the seat of all emotions.

Explanation:

William James & Carl Lange

There are many theories of emotions, but according to James Lang, and Carl Lange , the experience of emotion is based on the physiological aspects. They consider the emotions stem from the changes in the body like the heart rate raising or lowering, the shacking of hands.

The interpretation of the internal changes in the body account for the actual emotion. Being aware of this emotion will accompany an interpretation of that internal state.

-Cannon & bard theory

Contrary to the first theory, for Cannon and Bard, argue that many emotions share the same internal changes in the body, and not necessarily express as the same emotion.

For they the stimulus causes an internal change and the stimulus or event ocurrs, simultaneously as the emotion arises.

They see the subjective events as independent from the physiological events and identifies that the thalamus is responsible for being the seat of all emotions.
