Glutamatergic neurons in telencephalon, zebrafish

Neurons in the telencephalon of a 24 hour old zebrafish embryo starting to express glutamatergic genes. Confocal micrograph of a zebrafish embryo 24 hours post fertilisation viewed from a frontal aspect. Glutamatergic neurons are shown in cyan, neuropil in magenta, and axonal tracts in green. Even at this very early stage of development neurons in the olfactory epithelium, developing telencephalon and dorsal diencephalon are already expressing glutamatergic markers.
