Glycine‐immunoreactive neurons in the brain of a shark ( Scyliorhinus canicula L.)
ABSTRACT The glycinergic cell populations in the brain of the lesser spotted dogfish were studied by a glycine immunofluorescence method. Numerous glycine‐immunoreactive (Gly‐ir) neurons were observed in different brain nuclei. In the telencephalon, Gly‐ir cells were observed in the olfactory bulb,...
