About this work
Confocal micrograph of a single bipolar neurone expressing green fluorescent protein (GFP) in the midbrain of an adult transgenic zebrafish. This neurone has two distinct branching, tree-like structures (dendritic arbors or trees) that extend vertically out from the cell body (green circle; top centre of image). The two dendritic trees originate from opposite sides of the cell body, one large tree extends up (due north) and one smaller tree extends down (due south). These finger-like projections act like tiny sensors, picking up information (multiple sensory inputs) and passing on messages to other cells in the nervous system. Other axons and fibres expressing GFP in different layers of this region of the brain are also visible here (lower two-thirds of image). Width of image is 287 micrometres.
