What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book--part scientific overview, part memoir, part futurist speculation--describes Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual (if "romantic") belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a "fringy" subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness.
作者懒散的文风和满嘴跑火车的风格并不讨喜,夹叙夹议充斥自己鄙视的哲学论辩。 中心思想倒很明确,对意识的二元论思维嗤之以鼻,核心是神经元网络的整体互动关系产生意识,信息整合理论是作者信奉的意识理论。虽然信息科技的发展在信息处理的神经元整体数量级在逼近大脑神经元...
评分很有意思的书,讲什么是 consciousness 以及如何才算具有 consciousness、如何测量等等。虽然是以正经做学术的态度多年一直研究这个问题,但是书其实是一种比较科普的方式写出来的,当然最遗憾的是最终并没有一个解答。相比给出答案,更多地是提出了许多相关的问题和思考的方向...

LCGS 11 Chap 1 & 3 & 4 & 8 除去前文一些romantic but awkward confession (虽然还是可以感受到一位年过半百曾叱咤风云的前辈恳切的念叨) 后文的IIT倒是很值得一读 虽然有点尝试在physical property之外再界定一个mental property其实没有解决大卫查尔莫斯的HARD problem只是指出dark matter和dark energy作为一种新的基本property的可能 Integrated Information Theory is in its infancy and could turn out to be wrong, but it will at least illuminate 还是致敬了
评分前半部分都很好,提出了不错的问题。最后有点跑飞了,开始讲起宗教什么的。如果照作者自己说的,自我意识应该是可度量的一种现象,那又跟宗教有什么关系呢。
评分C. Koch 是组里的早期大师兄了,人和人的差距真是不要太大哈哈。 很有意思的书,讲什么是 consciousness 以及如何才算具有 consciousness、如何测量等等。虽然是以正经做学术的态度多年一直研究这个问题,但是书其实是一种比较科普的方式写出来的,当然最……
评分Allen Brain Institute是神作,这本书思路好飘忽==
评分深情的告白。 "Dave taught me an important lesson about philosophers..." 2333
