S1. Observed and fitted responses to reinforced and unreinforced licking for the neural responses shown in figures 7 and 8. These panels depict the activity elicited by the third unreinforced lick (bins 1 - 10) and by the tastant deliveries (bins 11 - 20). The observed firing patterns are presented in the left panels, and the corresponding best fits as returned by the glm are presented in the right panels. Note that the model accurately reconstructs the activity during the unreinforced licks. Note also that the background activity is of lesser magnitude than the corresponding tastant-evoked activity. Some unreinforced, lick-related activity can be seen at about 45 ms for 0.075 M MSG and at 75 - 90 ms for 0.075 M NaCl and 0.075 M sucrose. At 0.005 M, citric acid displays a broad peak from 75 - 135 ms.

S2. Observed and fitted responses to reinforced and unreinforced licking for the neural responses shown in figures 9 and 10. The conventions for this figure are the same as presented in S1. The observed firing patterns are presented in the left panels, and the fitted values are presented in the right panels. Note that the model accurately reconstructs the activity generated during unreinforced licking. In contrast to the activity presented in S1, lick-related signals arise early in this neuron and can be seen from 15 - 45 ms after the unreinforced lick and at 15 ms after the reinforced lick. Both sets of peaks are particularly evident in the panels corresponding to MSG, NaCl, and sucrose.

S3. Observed and fitted responses to reinforced and unreinforced licking for the neural responses shown in figures 11 and 12. The conventions for this figure are the same as presented in S1. The observed firing patterns are presented in the left panels, and the fitted values are presented in the right panels. As with the previous two examples, the activity of this neuron is clearly responsive to the unreinforced lick. Unreinforced licking elicits a broad peak of activity that can be most clearly seen in the panels corresponding to sucrose and quinine, with peaks occurring between 75 - 90 ms.
