Isolated Zebrafish Spontaneously Use Various Spatial Cues in Search of Conspecific

Zebrafish have been found recently to remember and return to the last seen location of a conspecific after being disoriented and returned to the environment 1 . This method - which harnesses the social nature of zebrafish to observe spontaneous navigation behavior and spatial memory – has advantages over the reinforced training paradigms used in the past in that it tests spontaneous reorientation, prior to the effects of domain general learning processes and allows for more valid comparisons of animal navigation to untrained human reorientation behavior (e.g., in children). The present experiments demonstrate the specific ways in which zebrafish spontaneously use geometry and features to compute relative directions and positions.
