| | CORTICAL REPRESENTATION OF THE EMOTIONS (Site not responding. Last check: 2007-10-23) |
 | | Emotional indicators include behaviors that are organized through the endocrine, visceral and somatic nervous systems that may induce changes in heart rate, breathing, capillary circulation, sweating, lacrimation, pupillary size, endocrine secretion and sphincter control, freezing, flight or fight, arousal, and species-specific vocalizations and emotional displays. |
 | | The concept of primary emotions evolved from the work of Darwin who suggested that certain emotions have as their substrate an innate neural basis since they are universally expressed and understood across cultures. |
 | | Although social emotions have a more balanced distribution of valence, in most formal situations positive emotional displays, such as cheerfulness or attentiveness, are expected in keeping with social "display rules", a term first coined by Ekman and Friesen. |
