title: Nervus terminalis innervation of the goldfish retina and behavioral visual sensitivity.
abstract: The possibility that axon terminals of the nervus terminalis in the goldfish retina regulate visual sensitivity was examined psychophysically. Fish were classically conditioned to respond in darkness to a diffuse red light conditioned stimulus. Bilateral ablation of the olfactory bulb and telencephalon had no significant effect on response threshold which was measured by a staircase method. Retinopetal nervus terminalis fibres thus appear to play no role in maintaining scotopic photosensitivity.
