Figure 1. Conditioning effect on taste reactivity.

Figure 1

0.15M LiCl (1% body weight) was injected immediately following 60 trials of 10 sec infusions of 0.2% saccharin in the conditioned group (n = 6), or 24 hrs later in the control group (n = 6). To determine the effectiveness of the modified behavioral paradigm, 5 ml of saccharin solution was continuously infused (I/O; 10 min per day) for five days. Aversive reactions were scored as the number of forelimb flail events during infusion. The conditioned group consistently displayed a high level of aversive reactivity to saccharin throughout test sessions, showing little to no sign of extinction.
