What is the Behavioral Activation System
*BAS - Left brain hemispheric activity marked by low to moderate autonomic arousal and a tendency to approach, which could characterize either happiness or anger.
What is the Behavioral Inhibition System
*BIS - Right brain hemispheric activity, which increases attention and arousal, inhibits action, and stimulates emotions such as fear and disgust
What is the James-Lange Theory
*Proposal that an event first evokes the autonomic arousal and skeletal responses and that the feeling aspect of emotion is the perception of those responses.
What is Limbic System
*Interlinked structures that form a border around the brainstem
What is a Panic Attack
*Period marked by extreme sympathetic nervous system arousal
What is a Pure Autonomic Failure
*Condition when output from the autonomic nervous system to the body fails
What is a Bed Nucleus of the Stria Terminalis
*A set of neurons that connect to the amygdala
What are Benzodiazepines
*Anti-anxiety drugs
What is Receptor/*GABA a Receptor
*Receptor complex structure that includes a site that binds GABA as well as sites that modify the sensitivity of the GABA site
What is a 5-hydroxyindoleacetic Acid
*The main metabolite of serotonin
What is a Panic Disorder
*Condition marked by frequent periods of anxiety and rapid breathing, increased heart rate, sweating, and trembling
What is a Startle Reflex
*Response that one makes after a sudden, unexpected loud noise or similar sudden stimulus
What is Turnover

What is Adrenocorticotropic Hormone

*field that includes the effects of diet, smoking, exercise, stressful expriences, and other behaviors on health
