(A) Concentration-response relationships for NaCl with and without 0.1 mM amiloride in the amiloride-sensitive type of taste neurons of control (Intact CT, n = 8) and cross-regenerated CT (CTc-IXp, n = 7). Vertical bars indicate SDs. (B) Response profiles to 0.1 M NaCl, 0.1 M KCl, 0.1 M NH₄Cl, and 0.01 M HCl in the amiloride-sensitive type (showing less than 50% of control NaCl responses after amiloride) of taste neurons of control CT (Intact CT, n = 14), cross-regenerated CT (CTc-IXp, n = 14), control IX (Intact IX, n = 2), and cross-regenerated IX (IXc-CTp, n = 4), and in the amiloride-insensitive type (showing more than 60% of control NaCl responses after amiloride) of taste neurons of control CT (Intact CT, n = 14), cross-regenerated CT (CTc-IXp, n = 14), control IX (Intact IX, n = 25), and cross-regenerated IX (IXc-CTp, n = 22). Vertical bars indicate SDs.
