Abstract
One-day-old chicks were trained with 100% concentration of a taste aversant chemical, methyl anthranilate (MeA), and tested for memory retention at 6 different time points (10, 30 and 70 minutes; 4, 8 and 24 hours) after training. The brain sections were examined with immunohistochemistry method. The number of cells which expressed Jun-like protein was counted under the microscope and analysed by ANOVA statistical system. The results showed that Jun-like protein expression was specifically activated by the learning course in one-day-old chicks. There existed differences among different areas in the brain, that is to say, more Jun-like protein in LPO than that in HV on the whole. Because Jun-like protein expression had similar tendency with the memory trace in chicks, it could be deduced that c-jun gene might play an important role in the consolidation and retention of the chicks’ memory.
