Document Summary
James-lange theory states that in response to internal or external situation, the autonomic nervous system creates physiological events such as muscular tension, a rise in heart rate, perspiration, and dryness of the mouth. Our brain would then process these information and tell us what our emotion is. Limbic system is a set of brain structure that includes the hypothalamus, amygdale, anterior thalamic nuclei, septum, limbic cortex and fornix. Serotonin and the ventromedial prefrontal cortex is important for regulating aggression. Stronger serotonergic tone seem to result in less aggression*: more serotonin = greater control of impulsive behaviour, still have motivation but can control behavior, complicated story. Low serotonin turnover measured by 5-hiaa correlated with impulsivity and aggression. In mice, social isolation decreases serotonin release c. Freezing behaviour is in response to anxiety: when a rat is in fear, it will jump.
