Effects of Colchicine on retention. Chicks were trained as described in the Materials and Methods. Colchicine (15 nmol/hemisphere) or saline was injected bilaterally into the IMMP 15 min post-training. Chicks were tested 3 and 24 h later. Results are presented as mean ± SEM, n = 45-60 for each group. (^*) P ≤ 0.020; (^**) P ≤ 0.0025. Statistical analysis of behavioral data was by analysis of variance (ANOVA), and where significant differences were found between groups, further analysis was made using a post hoc least-significant difference test.
