title: Acousticolateral and visual processing and their interaction in the torus semicircularis of the trout, Salmo gairdneri.
abstract: In the torus semicircularis of the trout, visual, auditory, visual-auditory, acousticolateral broadband, lateral line, visual-acousticolateral broadband and visual-lateral line units have been found, listed in decreasing frequency of occurrence. In contrast to the acousticolateral characteristics, the visual characteristics of toral units are poor; only sudden changes in the visual field seem to be of importance. When bimodal units are stimulated simultaneously with light and sound the responses of most units behave in a basically additive fashion. The activity of some units which responded to only one of the modalities could be modulated by the other modality.
