Neural connectome mapping describes how different types of neurons connect with each other and organs in the body. This cartoon (illustrated by Evelyn Xiaoya Zhao) shows a densely-stacked neuron network linked by dendrites and axons, together with nonneuronal cells including glial cells, endothelium, pericytes and many others. A new tissue clearing pipeline, TESOS, is designed to image a complete projection course of individual sensory neurons from mouse digits to the spinal cord. See page 124–139 by Yating Yi et al. for details.
