Fig. 13. Receptive field (RF) diagrams for units that were visually attributed to Eimer's organs. (A) RF for an afferent covering a single Eimer's organ in the coast mole. (B) RF for an afferent covering four separate Eimer's organs in the coast mole (1–4). (C) RF for an afferent covering a single Eimer's organ in a star-nosed mole. In A and B the right panels show responses to stimulation of the RF with and insect pin attached to the Chubbuck stimulator. In C responses are shown to a hand-held probe.
