Abstract

The aim of the present study was to investigate whether bottlenose dolphins have cerebral asymmetries of visual processing. The monocular performanceof the adult dolphin Goliath was tested using a large number of simultaneous multiple pattern discrimination tasks. The experiments revealed a clear right eye advantage in the acquisition and the retention of pattern discriminations as well as asymmetries in the interhemispheric transfer of visual information. As a result of a complete decussation at the optic nerve, thisright eye superiority is probably related to a left hemisphere dominance in visual processing. (C) 2000 Elsevier Science B.V.
