After the accident he was his personality and emotional life totally changed he became unreliable, irrelevant and impulsive and spent the rest of his life wandering the country before his death. Darwin"s book was the first major study on biopsychology, he developed the theory of evolutional emotional control. Signals of threat and submission and aggression are clearly different. According to this theory emotion-inducing sensory stimuli are received and interpreted by the cortex, which triggers changes in the visceral organs via the somatic nervous system. Then the autonomic and somatic responses trigger the experience of emotion in the brain.
