Neuronal morphology is a key attribute for distinguishing neurons and determining their cell type. Yet, tracing neurons in light-microscopic image stacks remains an arduous process. Wang et al. facilitate this task by incorporating virtual reality (VR) into the workflow. Their TeraVR platform is based on, and extends, the TeraFly tool for handling large image datasets. TeraVR facilitates tracing neurons in difficult conditions such as at low signal-to-noise ratios. The platform also allows faster tracing speeds than alternative software tools. An attractive feature of TeraVR is that multiple users can work on a particular neuron reconstruction together through the cloud, even if they are located in different cities. TeraVR is available as part of Vaa3D via https://github.com/Vaa3D.
