Glutamatergic neurons in the zebrafish forebrain

Glutamatergic neurons in the dorsal forebrain. Confocal micrograph of a 4 day old transgenic zebrafish viewed from a dorsal aspect. Glutamatergic neurons are shown in cyan and axonal tracts are labelled green. Neurons in the paired habenula nuclei in the dorsal diencephalon are strongly glutamatergic along with neurons in the olfactory bulbs, telencephalon and pretectum. Width of image is 500 micrometres.
