Research Abstract

In some cases, learning that occurs during the sensitive or critical period lays the foundation for future learning. Filial imprinting in precocial birds is the process of forming a social attachment during a sensitive period, restricted to the first few days after hatching. We showed that the thyroid hormone(T3) determines the start of the sensitive period. Imprinting training in chicks causes rapid inflow of T3 in brain vascular endothelial cells. The T3 thus initiated and extended the sensitive period to last more than 1 week and primed subsequent learning.The mechanisms included the activation of the immediate early genes and the morphological changes of dendritic spines in brain. The timing and duration of the sensitive period for learning has been believed to be developmentally fixed.However, there is now reason to believe thatlearning itself starts the sensitive period, and once "memory priming" occurs, the sensitive period does not close but remains open.
