| Outline of Final Research Achievements |
In this research, we focused on the laminar specification during cortical area formation in mammalian brain, and examined how an extrinsic factor, thalamic afferents, play a role in this step. By analyzing mutant mice in which thalamic afferents are ablated, we found the neuronal number was decreased in layer 4, the target layer of thalamic afferents, of the target area. It is suggested that thalamic afferents refine area-specific laminar structure by regulating neuronal number.
