Histological identification of recording locations in the brain. a Illustrations showing the positions of the brains of trout (top) and goldfish (bottom). Unlike goldfish, the trout brain is located far below the head surface. b Sample coronal section stained to show Nissl material from a trout telencephalon (Trout B). The arrowheads depict the estimated recording locations. For reference, a mirror image outline of the brain section was drawn on the left. c All estimated locations for the three trout (color-coded dots) are depicted on the brain section outlines (Dm = pars medialis; Dl = pars lateralis, in the dorsal pallium). d Color-coded planes indicate the locations of the coronal brain sections where the recording locations were estimated for the three trout shown in c
