AbstractStudied the correlation between the opioid peptide: Leu-enkephalin (L-Enk), Β-endorphin (Β-End), and dynorphin (Dyn) in the brain and the monocular learning of 1-day-old chicks. 44 male 1-day-old chicks were divided into a learning group (LG, 20 Ss), a nonlearning group (NLG, 12 Ss), and a control group (CG, 12 Ss). Ss in LG and NLG had 1-trial taste avoidance training and/or memory test after 24-hr left-eye vision deprivation. The levels of L-Enk, Β-End, and Dyn were measured with radioimmunoassay. The results show (1) that after left-eye vision deprivation in NLG, the Β-End level increased; the Dyn level decreased; the L-Enk level was similar to that of CG; and (2) that after the training in LG, the Β-End level reduced and the Dyn level increased to similar levels of CG; the Dyn level of the right hemisphere was even higher than that of NLG; the L-Enk level had no difference to other groups, and the L-Enk level of the right hemisphere was higher than the left hemisphere. The study concludes that stress caused by depriving left-eye vision is an important factor in memory impairment; that monocular learning helps a new balance of the opioid peptide; and that L-Enk, Β-End, and Dyn participate in the process of learning and memory.
