Cover picture: Confocal image of the developing cerebellum (postnatal day 7) double-labeled with Msi2 (red) and Hu (green). Msi2 is primarily expressed in the superficial layer of the external granule cell layer (EGLa) and in Bergmann glial cells, whereas Hu is in the deeper layer of the EGL (EGLb) and in granule neurons in the internal granule cell layer (IGL). Purkinje neurons express both Msi2 and Hu proteins (yellow). For details, see the article by Sakakibara et al. in this issue (pages 8091-8107).
