Trigeminal sensory neurons in 3-day old zebrafish

Imaged in vivo on Olympus FVB using a 20X 0.95NA dipping cone objective. Three fluorescence channels were acquired sequentially.

The trigeminal sensory neurons (the cells next to the eye) and their axons (the branches emanating from the cell bodies) are labeled by Brainbow transgenic expression. The axons of these sensory neurons extend into the brain (the horizontal bundle on the right side), where they encounter neurons within the brain. The color in the eye is due to tissue autofluorescence.
