Coloured scanning electron micrograph (SEM) of a spinal, or dorsal root, ganglion cell that has been grown in culture for 12 hours. A spinal ganglion is a node of nerve cells that is located just outside the spinal cord, along the spinal nerve. These cells are responsible for processing sensory information or for coordinating impulses from other neurons. The picture was created as part of a cooperation with Quintessenz Publishing. Magnification: x800 when printed at 15cm wide.
