Abstract:
:Analysis of single fibers isolated from a branch of the facial/trigeminal complex innervating the maxillary barbel of the channel catfish, Ictalurus punctatus, indicated the existence of bimodal (taste/tactile) fibers. Of the 60 single fibers recorded, 14 (23%) responded to both taste (amino acid) and tactile stimulation, 43 (72%) were responsive to only tactile stimulation and three (5%) responded only to taste stimulation. Quinine hydrochloride at a concentration of > or = 1.0 mM suppressed the mechanosensory activity of the bimodal fibers, but had no effect on the tactile-only fibers.

CHEMICAL SENSES文献大全abstract::The strong bond that is formed between ewe and lamb after parturition is important for lamb survival. Evidence exists that the ewe mainly employs olfactory recognition cues to distinguish her lamb from other lambs in the flock.
