[Conscious perception of a stimulus as a somatopsychic process]

Autonomic (heart rates, electroplethysmograms, pneumograms, blood coagulation) responses to the threshold and subthreshold concentrations of cordiamine and tifene odogenes were studied in 58 healthy young females. There were autonomic shifts to subthreshold odogenes and a relationship between the detection threshold of a stimulus to the baseline activity of the autonomic nervous system and to the amplitude of autonomic changes. It is suggested that autonomic (somatic) changes make their contribution to the conscious (psychic) perception of a stimulus.
