摘要：

This study compared both behavioral and electrophysiological responses to NaCl in young and old Fischer-344 rats. These comparisons were made in the same individuals. Preference for NaCl solutions versus water was assessed using two-bottle preference tests. The integrated response of the chorda tympani nerve to NaCl was recorded. NaCl neural-response magnitude and corresponding behavioral sensitivity appear to decrease with age in the Fischer-344 rat at concentrations greater-than-or-equal-to 0.15 M and neural-response magnitudes increase at lower concentrations.
