Figure 3. Intake of quinine.
Water deprived rats were trained to drink 0.0003M QHCl. On the test day they were treated with either vehicle (Veh; n=6) or 2.4 μg/kg Ex-4 (n=6) 15 min before being placed in the chamber where they had access to 0.003M QHCl. A Mean log 10 latency (sec) to emit the 1st lick for 0.003M quinine. B. Mean number of licks/15 min emitted for 0.003 M Quinine. C. Mean log 10 Inter-lick interval. Vehicle: white bars, n=6. Ex-4: black bars, n=6. **p<0.001.
