Research Abstract

We analyzed the gene-expression of Netrin-1 using the brain of newly hatched chick. As the result, we identified the Intermediate Medial Hyperpallium Apicale (IMHA) as the novel region related to filial imprinting.
When the vector for the expression of microRNA besed on the sequence of microtubule-associated protein (MAP2) gene introduced to the region related to filial imprinting, endogenious MAP2 protein was decreased, and memory formation was inhibited during filial imprinting.
