No effects of LPO lesions on novel training.A, B, Total number of trials (A) and number of incorrect trials (B) during the novel training procedure (Fig.2Bd) were compared among three groups of chicks: sham, cLPO-, and rLPO-lesioned chicks. Training continued until chicks met the criteria of correct choice in six successive trials. The cLPO-lesioned chicks tended to have longer training times than others, although no statistically significant difference was found.C, The number of correct choices per 12 test trials was compared, and no significant differences were found among groups.D, The number of pecks required for chicks to ingest five pellets showed no significant differences among groups, suggesting that the pecking accuracy was unimpaired. Columns and error bars indicate mean ± SEM, respectively. One-way ANOVA was adopted after Bartlett's test, both at p < 0.05.
