Abstract

Background: Numerous studies have confirmed that stimulating the mid-brain motor nuclei can regulate movement forcibly for robo-pigeons, but research on behavior modulation using non-motor nuclei is scarce.

Objective: In this study, we constructed a spatial preference behavior by stimulating the stratum griseum periventriculare (SGP), a nucleus correlated with fear and escape, for robo-pigeons.

Methods: The study was carried out in a square-enclosed experimental field, with a designated box serving as the 'safe' area for the robo-pigeons. If the robo-pigeon exits this area, the SGP will be stimulated. After a brief training period, the robo-pigeons will have a clear spatial preference for the box.

Results: The result from five pigeons has shown that, after simple training, the animals develop a spatial preference for the box. They can quickly return to the box in any situation when the SGP is stimulated, with a success rate exceeding 80% (89.0 ± 6.5%). Moreover, this behavior is highly stable and remains consistent, unaffected by changes in the location of the box or the interference box.

Conclusion: The results prove that using the electrical stimulus could enable animals to accomplish more complex tasks. It may offer a novel approach to regulating pigeon behavior and further advance the study of cyborg animals.

以恐惧核为目标的电刺激诱发机器人鸽的空间偏好行为

背景：大量研究证实，刺激中脑运动核团可以强制调节机器鸽的运动，但利用非运动核团调节行为的研究却很少：本研究中，我们通过刺激与恐惧和逃跑相关的脑室周围灰质层（SGP），为机器鸽构建了一种空间偏好行为：研究在一个方形封闭的实验场地中进行，实验场地中有一个指定的盒子作为机器鸽的 "安全 "区域。如果机器鸽离开这个区域，SGP 就会受到刺激。经过短暂的训练后，机器鸽会对盒子产生明显的空间偏好：五只鸽子的训练结果表明，经过简单的训练后，鸽子会对盒子产生空间偏好。在任何情况下，当刺激 SGP 时，它们都能迅速返回盒子，成功率超过 80%（89.0 ± 6.5%）。此外，这种行为还具有高度稳定性和连贯性，不受盒子位置或干扰盒变化的影响：结果证明，使用电刺激可以使动物完成更复杂的任务。这可能为调节鸽子行为提供了一种新方法，并进一步推动了对半机械动物的研究。
