Interoception —sensory function without perception
More than a hundred years ago Cyon and Ludwig published their work on the function of the depressor nerve originating in the aortic arch. Forty years later, in 1906, Sherrington, making use of additional knowledge gained on sensory function in the internal organs, incorporated interoceptors in the physiology of sense organs. It is a peculiar feature of this field that seventy years later interoception has still not been accepted fully as an integral part of the sensory apparatus. This is particularly striking, because in recent years there has been a constant flow of publications on the peripheral mechanism of receptors found in high numbers in the cardiovascular, gastrointestinal, urogenital, and respiratory systems. On the one hand, there are interesting data on interoception, while on the other, a synthesis is still lacking. What is the reason for this contradiction? In our opinion it should be sought in the overwhelmingly psychophysical interpretation of experimental findings, without trying to formulate a standard view on central regulation. In the psychophysical sense, sensory function is dependent on subjective sensation (which can be recorded by psychological methods) arising in response to stimulation of a receptor.
