Neuroticism (N): biological systems are1. Limbic system2. Autonomic nervous system (ANS) sympathetic and parasympathetic - Those who are neurotic seem to have more physiological arousal (increase in sympathetic division of ANS)o Current research hasn’t seemed to support this theoryF. Psychoticism (P): thought to be an increase to maleness and increase in testosterone also an increase in neurotransmitter dopamine (high levels of dopamine and glutamate are implicated in
