Scanning electron micrograph of tree-like branches (dendritic tree) spreading out from a particular type of nerve cell (Purkinje cell, or neurone) found in the brain. The finger-like projections in this elaborate network act like tiny sensors, picking up information and passing on messages to help control and coordinate muscle movement. This particular neurone is from the cerebellar cortex in a rat brain. To allow us to see the dendritic tree, this Purkinje cell was filled with a visual marker before being imaged by focused ion beam scanning electron microscopy, which allows neurones and neural circuits to be reconstructed in high resolution. The width of the image is 110 micrometres (0.11 mm).
