Novel taste decreases the expression of Arc/Arg3.1 in the gustatory cortex for few hours. a 1 h following drinking Arc/Arg3.1 mRNA levels were elevated in both the water (n = 5) and 0.1 % saccharin groups (n = 6) compared to the water restricted (n = 5) group *p < 0.05, **p < 0.01. b Novel taste learning induced reduction in Arc/Arg3.1 mRNA expression hours following learning. Immediately after the end of drinking session- 0 h (water, n = 11; saccharin, n = 11; water restricted, n = 11), 1 h (water, n = 20; saccharin, n = 20), 3 h (water, n = 8; saccharin, n = 9), 6 h (water, n = 14; saccharin, n = 14), 24 h (saccharin, n = 11; water, n = 12) * p < 0.05, ** p < 0.01. c Novel taste learning reduced the amounts of Arc/Arg3.1 mRNA expression, compared to 25 days of familiar saccharin group (1 h: familiar saccharin, n = 5; novel saccharin, n = 5) * p < 0.05. d Arc/Arg3.1 expression does not change in the non-relevant occipital cortex 6 h following novel taste learning (saccharin, n = 6; water, n = 6, p = 0.82)
