Noam Hassenfeld: 本期节目探讨了人类感官的局限性以及我们对宇宙的认知。我们从亚里士多德提出的五种感官出发,讨论了人类是否真的只通过这五种感官来获取所有知识。Noam Hassenfeld 认为,我们可能拥有更多感官,例如内感受(interoception),它包括饥饿感、口渴感和膀胱充盈感等。此外,我们还讨论了本体感受(proprioception),即感知自身在空间中位置的能力。通过对缺乏本体感受的患者的案例研究,我们了解到本体感受依赖于Piezo2受体,而缺乏该受体的患者在闭上眼睛后无法准确感知自身位置,这表明触觉可能包含多种感官,并且感官之间存在重叠和相互影响。Noam Hassenfeld 还指出,大脑将各种感官输入整合为单一的意识,这是一个神奇而神秘的过程。 Brian Resnick: 我们讨论了感官数量的争议,有人认为只有三种,也有人认为有九种、二十一种甚至三十三种。我们还探讨了本体感受(proprioception)的机制,以及缺乏Piezo2受体对本体感受和触觉的影响。Brian Resnick 指出,人类的眼睛只能看到可见光,这只是电磁波谱的极小一部分,这意味着我们对宇宙的感知极其有限。我们还讨论了暗物质和暗能量,它们构成了宇宙的大部分,但我们无法感知它们。Brian Resnick 认为,我们可以通过技术来扩展我们的感官,例如韦伯望远镜可以帮助我们观测红外线,从而了解宇宙的起源。他强调,感官提醒我们知识的局限性,保持好奇心,探索未知领域非常重要。

Shownotes Transcript

Why stop at five senses? Just how much of the world can we perceive? And how much is out there that’s still out of reach, hiding in the dark?
