Chapter 10 provides a comprehensive summary of the field of emotion. The first section defines two aspects of emotion: responses and feelings. The central nucleus of the amygdala is described as integrating emotional responses. Phineas Gage is described as an exemplar of the effects of damage to the orbitofrontal cortex. The history and problems of the prefrontal lobotomy procedure conclude the section. The next section describes the function of facial expressions in communicating emotion and neural systems involved in recognizing emotion communications. Section three covers the James-Lange theory of emotional feelings. Cannon’s objections are portrayed as ineffective and the section describes research supportive of the James-Lange theory. The final section of the chapter covers the topic of aggression including neural and hormonal controls.

After completing the chapter, each student should be able to:

• Discuss the behavioral, autonomic, and hormonal components of an emotional response.
• Describe the role of the amygdala in emotional responses.
• Discuss the role of orbitofrontal cortex in the analysis of social situations.
• Describe the impact of damage to orbitofrontal cortex on social responding.
• Discuss cross-cultural studies on the expression and comprehension of emotions.
• Discuss the neural control of the recognition of emotional expression in:
• Normal people
• People with brain damage
• Discuss the James-Lange theory of emotion.
• Describe the supporting research for the James-Lange theory of emotion.
• Discuss the nature, functions, and neural control of aggression.
• Discuss the hormonal control of
