3-D analysis of intact mouse hippocampus

CLARITY provided this 3D view showing a thick slice of a mouse brain’s memory hub, or hippocampus. It reveals a few different types of cells: projecting neurons (green), connecting interneurons (red), and layers of support cells, or glia (blue). Conventional 2D methods require that brain tissue be thinly sliced, sacrificing the ability to analyze such intact components in relation to each other. CLARITY permits such typing of molecular and cellular components to be performed repeatedly in the same brain. S
