Abstract：
:Filial imprinting is the behavior observed in chicks during the sensitive or critical period of the first 2-3 days after hatching; however, after this period they cannot be imprinted when raised in darkness. Our previous study showed that temporal augmentation of the endogenous thyroid hormone 3,5,3'-triiodothyronine (T3) in the telencephalon, by imprinting training, starts the sensitive period just after hatching. Intravenous injection of T3 enables imprinting of chicks on days 4 or 6 post-hatching, even when the sensitive period has ended. However, the molecular mechanism of how T3 acts as a determinant of the sensitive period is unknown. Here, we show that Wnt-2b mRNA level is increased in the T3-injected telencephalon of 4-day old chicks. Pharmacological inhibition of Wnt signaling in the intermediate hyperpallium apicale (IMHA), which is the caudal area of the telencephalon, blocked the recovery of the sensitive period following T3 injection. In addition, injection of recombinant Wnt-2b protein into the IMHA helped chicks recover the sensitive period without the injection of T3. Lastly, we showed Wnt signaling to be involved in imprinting via the IMHA region on day 1 during the sensitive period. These results indicate that Wnt signaling plays a critical role in the opening of the sensitive period downstream of T3.
