DISCRIMINATION BETWEEN EQUIMOLAR NACL AND LICL SOLUTIONS BY ANOSMIC ADRENALECTOMIZED RATS

Laboratory rats, either made anosmic or subjected to sham operations, were later rendered capable of discriminative preference for NaCl over an equimolar LiCl solution. During a series of two-bottle tests (NaCl opposite LiCl), the importance of olfaction relative to that of taste in the discrimination was determined by such measures as initial fluid intakes, first min alternations, and first min fluid intakes. The rats proved able to distinguish by taste between the solutions, and olfactory cues were neither required nor important in the discrimination. © 1968.
