The appearance of the optic tectum stained with MAB 1H12 was that of a strongly laminated structure with layers of neuronal cell bodies alternating with relatively somata-free zones.
When we injected directly into the brain third ventricle of medium sized fish, cells in the telencephalon, optic tectum, and occasionally in the hypothalamus (not shown) were transfected with CMV-GFP (800 ng in 2 [micro]L).
