Mean (+SEM) licks (in 20-s trials) for an array of taste solutions by K+-deprived and replete rats in Experiment 1. Relative to replete rats, K+-deprived rats licked more 100 mM CaCl2 and 100 mM MgCl2 but less dH2O, 10 mM citric acid, 100 mM sucrose, and 200 mM KHCO3. Group differences in taste evaluation of NaCl and KCl solutions may have been masked by the fact that both K+-deprived and replete rats licked maximally for these solutions. Inset. Analysis of taste solutions for which lick responses were well below the maximal lick rate. Mean (+SEM) ratios of brief access licking for 100 mM CaCl2, 100 mM MgCl2, 100 mM FeCl2 and 10 mM citric acid relative to the number of licks expressed for water. Relative to replete rats, K+-deprived rats showed significant increases in licking for the chloride-containing salt solutions. (*, significantly different from replete rats, p < 0.05)
