Effects of chronic food satiety on rGT performance. Compared with baseline (BL), satiation with regular chow did not drastically affect choice behavior in any group. A, B, Sham-control rats chose P2 slightly less on the first day of chronic feeding (A), whereas a similar effect was observed for rats with unilateral lesions on the second chronic feeding day (B). C, D, There was no significant effect of chronic feeding in either the ipsilateral (C) or contralateral (D) lesion rats; however, visual inspection of the data indicated that a similar effect (decreased choice of P2) was initially observed. Data are represented as the mean percentage choice of each option ± SEM.
