Artist's impression of the cellular structure of part of a developing zebrafish retina. The retina is almost fully developed so all the cells have been born and have almost finished moving into one of three layers depicted here. The top layer is the ganglion cell layer which contains retinal ganglion cells. The middle layer (inner nuclear layer) contains horizontal cells (green), bipolar cells (yellow), Mueller cells (white) and amacrine cells (red). The cells in the bottom layer are cells of the outer nuclear layer (rods and cones). This acrylic painting was inspired by multi-coloured fluorescent proteins which are used to label different types of cells and different compartments inside a cell (e.g. nucleus, membrane, cytoplasm). This gives an instantaneous view of the spectrum of cell fates within a neural tissue.

When considering the intelligence of individual cells, certain things stand out. Cells know exactly where they are and how to travel to far away places through many kinds of terrain with many different techniques. Cells know how to signal back and forth wirelessly to many different types of cells using many different…
