The effect of previous exposure to lateral sensory stimuli in shaping the response to subsequent symmetric stimuli represents an important overlooked issue in neuroethology, with special reference to arthropods. In this research, we investigated the hypothesis to 'programme' jumping escape direction as well as surveillance orientation in young and adult individuals of as an adaptive consequence of prior exposure to directional-biased predator approaches generated by a robotic leopard gecko representing The manipulation of the jumping escape direction was successfully achieved in young locusts, although young did not exhibit innately lateralized jumping escapes. Jumping escape direction was also successfully manipulated in adult locusts, which exhibited innate lateralized jumping escape at the individual level. The innate lateralization of each instar of in using a preferential eye during surveillance was not affected by prior lateralized exposure to the robotic gecko. Our results indicate a high plasticity of the escape motor outputs that are occurring almost in real time with the perceived stimuli, making them greatly adaptable and compliant to environmental changes in order to be effective and reliable. In addition, surveillance lateralization innately occurs at population level in each instar of Therefore, its low forgeability by environmental factors would avoid disorganization at swarm level and improve swarm coordination during group tasks. These findings are consistent with the fact that, as in vertebrates, in insects the right hemisphere is specialized in controlling fear and escape functions.
先前暴露于侧向感觉刺激对面后续对称刺激反应的影响，代表了神经行为学中一个重要的被忽视问题，特别是在节肢动物中。在这项研究中，我们研究了这样一种假设，即作为对由机器人豹纹壁虎代表的定向有偏差的捕食者接近所产生的先前暴露的适应性后果，“编程”跳跃逃避方向以及幼体和成年个体的监视方位。年轻蝗虫的跳跃逃避方向的操纵得以成功实现，尽管年轻的 本身不具有天生的侧向跳跃逃避反应。在个体水平上具有天生的侧向跳跃逃避反应的成年蝗虫，其跳跃逃避方向也可以成功地操纵。在监控过程中使用优势眼的每个龄期的 的先天侧向化，不受先前对机器人壁虎的侧向化暴露的影响。我们的结果表明，逃避运动输出具有很高的可塑性，可以几乎实时地与感知到的刺激一起发生，从而使其具有很大的适应性和灵活性，可以根据环境变化进行调整，以实现有效性和可靠性。此外，在每个龄期的 中，监视的先天侧向化都发生在种群水平上。因此，其环境因素的低可锻造性将避免在群体水平上的混乱，并在群体任务期间提高群体协调能力。这些发现与以下事实一致，即与脊椎动物一样，在昆虫中，右半球专门用于控制恐惧和逃避功能。
