Rat neurones, SEM

False-coloured scanning electron micrograph of cell cultured rat cerebellar granule neurones. Neurones are cells in the nervous system which carry information in the form of electrical signals and allow us to sense and respond to our environment. At the centre of the image is a cell body surrounded by axons and dendrites. Dendrites bring electrical signals into the cell body while axons carry information away from it. Horizontal width of image is 39 micrometres.
