A Motor Component to the Memories of Habitual Foraging Routes in Wood Ants

摘要: Ants are so low to the ground that slight undulations in terrain over which they navigate will cause large and unpredictable changes their view of scene around them. We describe here evidence a form motor learning helps ants follow usual route when guiding landmarks vanish from sight. Wood were trained approach vertical bar presented at varying positions on LCD screen. In different experiments, was either stationary, moved smoothly, or jumped between two stationary positions. these three ways followed straight, curved, two-leg routes, respectively. Once accustomed approaching starting points, made disappear during approach. often continued straight curved paths, despite missing landmark, showing can perform complex routes with no more than intermittent visual feedback.
