D: Cannon-Bard Theory

The Cannon-Bard Theory is that emotional expression results from the function of hypothalamic structures, and emotional feeling results from stimulations of the dorsal thalamus.

Cannon-Bard theory states that we feel emotions and experience physiological reactions such as sweating, trembling, and muscle tension simultaneously.
