Extended Data Fig. 4

Rates of responding are represented as time spent in the food port (%; ±SEM). Rats (n=12 eYFP, n=8 NpHR) learnt to distinguish between A2 and B2 during conditioning, with no difference in the rates or ultimate levels of learning between groups A repeated-measures ANOVA revealed a main effect of stimulus (F1,18=3.553, p=0.076), and a stimulus x session interaction (F2,36=8.281, p=0.001; stimulus × group: F1,18=0.13, p=0.911), with follow-up comparisons, granted by the significant stimulus x session interaction, showing an increase in learning about A2 across sessions (F2,17=8.860, p=0.002), that was not present with relation to B2 (F2,17=1.953, p=0.172).
