[The hunger dominant in man and the reactions of the autonomic nervous system]

Formation of hunger dominant takes place in man under the conditions of alimentary deprivation and application of sensory stimuli. Summation reactions, namely, swallowing movements, appear in response to the stimuli. Time of deprivation necessary for dominant formation is different in different subjects. Study of ECG, GSR, and respiration during the dominant formation revealed an increase of vegetative reactivity during application of the testing stimuli and before the summating swallow as well. The obtained data allow to make a conclusion on the active participation of the vegetative component in the formation of dominant constellation. The former joins the summation process earlier than the motor component.
