The winners of the Olympus BioScapes Digital Imaging Competition have just been announced. First prize went to this quadruple-fluorescence confocal image of the mouse retina, by Thomas Deerinck of the National Center for Microscopy and Imaging Research at the University of California, San Diego. The image shows the optic nerve layer of the retina. Glial cells are coloured green and retinal ganglion cells are orange. The fibres of the optic nerve are red, and blood vessels are blue.
The confocal images below were all given an honorable mention in the competition:
Transgenic rat retina, by Josh Morgan. The light-sensitive photoreceptor cells are the purple cells in the top half of the image.
Drosophila brain, by Balaji Iyengar of the Department of Physiology at the University of Toronto.
Rat cerebellum, by Hiroaki Misono of the Biomedial Sciences Dental School at the University of Maryland. The large purple structures in the lower half of the image are cerebellar Purkinje cells; their extensive dendritic trees, and the parallel fibres with which they form synapses, are coloured turquoise.
