IV. Afferent Systems

This section includes brief considerations of receptor function, sense modalities, fiber types in peripheral nerve, -loop activity, central conduction paths and switching points, and negative feed-back from higher to lower sensory switching station.

1. Receptor Function.—

Receptors respond to mechanical, thermal, electromagnetic (as light), and chemical energies. Except for pain, where the form of energy is nonspecific so long as the damage level for the surround of the receptor is exceeded, different receptors are specific for different kinds of energy. A striking example is the infrared organ situated in the facial pit of the viper. Formerly believed to detect air vibrations, these have more recently been shown to be a most sensitive detector of the snake's prey (Noble and Schmidt⁴¹⁷; Bullock and Dieke.¹¹⁰ Besides specificities . . .
