title: Interocular transfer of preoperatively trained visual discriminations in goldfish (Carassius auratus) following selective commissure transections.
abstract: Goldfish were monocularly trained on either a red/green or circle/square discrimination task to show a differential classically conditioned cardiac deceleration. Combined section of the minor and horizontal commissure was then performed in animals trained on the colour problem, and transection of the posterior commissure in fish which had acquired the shape task. Both groups were then examined for retention and transfer. The results indicate that the engram for colour is fully represented bilaterally whilst that for shape is only established weakly in the naive side.
