Spiny neuron, 2009. Electron microscopy grants researchers and clinicians access to a universe that is too small to be detected using light-based microscopes. This photomicrograph was obtained by scanning a beam of electrons across the sample while a detector kept track of electrons bouncing off its surface, betraying the specimen’s outer shape. It shows a soma with dendrites radiating from it.
