NACL-PREFERRING NZB B1NJ MICE AND NACL-AVOIDING CBA/J MICE HAVE SIMILAR AMILORIDE INHIBITION OF CHORDA TYMPANI RESPONSES TO NACL/

Integrated chorda tympani nerve responses to NaCl were studied in two mouse strains, an NaCl-preferring NZB/B1NJ and an NaCl-avoiding CBA/J. The NaCl responses of both strains had similar magnitude and were sup pressed by amiloride to a similar extent. This suggests that periphera l gustatory responsiveness to NaCl is not the only mechanism underlyin g mouse strain variation in NaCl acceptance.
