The effects of lithium upon drinking in the pigeon and rat

Single administrations of LiCl in fluid deprived pigeons produced immediate and sustained drinking which was (a) significantly greater than in NaCl-injected birds, (b) a function of the dosage of lithium, and (c) persistent for several days following the highest dosage used. Experiment 2 employed the same procedures to examine the effects of lithium upon fluid consumption in the rat. Results indicated that single administrations of lithium had little effect on water consumption.
