Imaging at various depths. By adjusting the position of the focal plane inside the brain, it is possible to analyze the topology and distribution of vascular networks at different depths in the brain. The red arrows mark some penetrating arterioles. The red circle on (b) depicts an arteriole that penetrates up to 500 μm deep in the brain before branching.
