研究表明蜘蛛会做梦吗?

蜘蛛在人类世界中的名声并不好,因为许多人都有蜘蛛恐惧症--害怕蜘蛛。 不过,也有一些人喜欢与蜘蛛为伴,喜欢把它们当作宠物饲养。

如果您是不喜欢蜘蛛但又不害怕蜘蛛的人,那么下次在家里看到蜘蛛时,不要直接把它们赶走,因为它们有可能在做梦。 是的,这一突破性发现是由行为生态学家达妮埃拉-罗斯勒博士(Daniela Rößler)提出的。

2020 年,她在实验室观察悬挂的跳蛛时偶然发现了这一发现。 罗斯勒博士及其研究团队的研究成果现已发表在《美国国家科学院院刊》(PNAS)上。

Rößler 博士是德国康斯坦茨大学的一名研究员,她最初的目标是研究蜘蛛中捕食者与被捕食者之间的相互作用。 在这次实验中,她使用了小蜘蛛,并用红外摄像机拍摄了它们在夜间的活动。

在这一过程中,她发现一群跳跃蜘蛛倒挂在一根丝线上,腿部整齐地蜷曲着。 在睡眠阶段,蜘蛛的四肢会移动,但也有一些不活动的阶段。

此外,研究小组还发现,这些蜘蛛表现出类似快速眼动(REM)的行为--这是人类和大型动物在睡觉时经常会出现的行为。

此外,在快速动眼期做梦的几率也很高。 在快速动眼期,身体的各种活动都会升级,例如心脏。 而这一切都发生在眼睛闭着并快速运动的时候。

我一直很想分享我们最新发现的消息 🥳你以为跳蛛的酷劲已经登峰造极了吗? 扣好安全带!!我们需要谈谈 #跳蛛潜在的 #梦想。 @PNASNews

过程是如何开始的?

毫无疑问,对蜘蛛进行脑部扫描并不像对其他大型动物那样容易。 此外,您也无法询问它们梦见了什么。 因此,办法就是观察它们,而这正是罗斯勒博士在她的实验室里所做的。

她使用放大镜和夜视摄像机来了解蜘蛛的睡眠习惯。 在实验过程中,她着重观察了蜘蛛的眼睛和身体动作,因为这些动作提供了蜘蛛睡眠模式的线索。

渐渐地,她发现视网膜快速运动的持续时间和频率在整晚都在增加,持续时间约为 77 秒,大约每 20 分钟出现一次。

此外,Rößler 博士还注意到,在这些类似于快速眼动的阶段中,身体动作不协调,腹部摆动,双腿蜷曲或松开。

罗斯勒博士在接受《国家地理杂志》采访时强调,她还没有证明蜘蛛的这种非活动期在技术上被认为是睡眠期。 为此,还需要进行一些调查,包括表明蜘蛛的唤醒能力较弱,对刺激的反应较慢,如果被剥夺睡眠,就需要 "反弹睡眠"。

事实上,这是科学家在动物身上观察到快速眼动睡眠的首次突破,尤其是那些没有脊柱或背骨的动物。

希望研究小组在探索动物王国做梦过程的同时,能取得突破性成果!
