GABAergic and Glutamatergic neurons in the zebrafish brain

This image shows the forebrain of a 4 day old zebrafish larvae viewed from the left hand side. Both inhibitory and excitatory neurons can be seen. Inhibitory neurons (green) use gamma-Aminobutyric acid (GABA) and excitatory neurons (magenta) use glutamate as transmitters. The extensive neural network has been labelled with an antibody for tubulin, a cytoskeletal protein (cyan). Width of image is 500 micrometres.
