    • 1929, The Australasian Journal of Psychology and Philosophy, page 310:
      He divides receptors into three classes— "nociceptors", such as the nerve-endings for pain and hunger, "beneceptors", such as the nerve-endings stimulated when sugar melts on the tongue, and "neutroceptors", such as the nerve-endings in the eye and ear, called " neutroceptors" because they receive more or less indiscriminately both pleasant and unpleasant messages.
    • 1973, Behaviorism, page 42:
      The “beneceptors,” “nociceptors,” and "neutroceptors” generally signalled stimuli that were, respectively, beneficial, harmful, or neutral as regards the organism or its species.
