Retina flight 2013

Volume reconstruction of 950 nerve cells in a block of mouse retina. Each color represents one neuron. Flight along the blood vessels (appearing as “tunnels” in the dense web of neuronal processes). When diving into the nerve cell tissue, a large fraction of the volume is densely filled with nerve cell fibers, the “cables” in the brain. Glia cells and nerve cells that had their cell bodies outside of the data block are not shown. Helmstaedter et al., 2013; © Max Planck Institute for Medical Research, Heidelberg, Germany

At the micro-scale the brain is a mess; a thick tangle of nerve cells connected at synapses. Mapping just a tiny portion of this mess, a few hundred cells, is a huge challenge. You have to wonder if it's worth the effort. But seeing exactly how brain cells are wired together is giving us new insights into brain function. The researchers who made the 3D maps in this video discovered a new type of cell and worked out how insects see movement. If you've ever tried to swat a fly you'll know how good they are at sensing motion! © Nature, 2013
