It is known that adolescent brain development and subsequent brain function are largely affected by the environment and experience. For example, growing up abroad allows children to become bilingual, which is a positive influence on brain function. However, children who have a history of neglect or physical abuse are at risk of developing psychiatric problems. Often these psychiatric problems appear later in their life which makes it difficult to solve and treat the disorder. How are these bad memories 'stored’ and then appear in their later life? One possibility is, under a stressful environment, the maturing child’s brain generates fragile circuits which are not strong enough to survive during adulthood. Therefore, it is important to understand the mechanism of neuronal circuit development which is controlled by environment and experience. In my lab, we are focusing on mouse thalamus-cortex connections to dissect how neuronal circuits are refined by neuronal activity and reveal the molecular mechanisms which underlie it. Moreover, we are trying to understand how the young brain can rewire its circuits to develop cross-modality, and thus compensate for lost connections.
