Homeostatic, neuroendocrine regulation in man is affected by psychic stimuli. Man reacts not only to the actual existence of danger, but to threats and symbols of danger experienced in the past. Man wants to be prepared to meet a new situation the moment it appears. This creates a situation in which homeostasis is adjusted not only to the needs of the organism in the prevailing conditions but to the anticipated needs as well. Irrespective of whether this preparedness is adequate or not, it affects the adaptive-protective mechanisms of the living organism. The organisms pattern of response involves physiological as well as psychic processes. The assessment of causal connexions has been made easier by the use of psychophysiological experiments, in which various emotional reactions are first induced and then studied together with the accompanying physiological phenomena. The results of such experiments are summarized.
