This confocal image depicts the morphological details of cerebellar molecular layer interneurons (MLIs). Single MLIs are lighted up in orange using Cre-dependent fluorescent markers. MLI nuclei are labelled in cyan using nuclei-targeted GFP. Cerebellar Purkinje neuron somas are labelled by NeuroTrace and shown in green. For more details, see the article by Carriere et al. (pages 8652–8668). Cover Image: Wendy Xueyi Wang.
