In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful.

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 t

After receiving the Nobel prize along with James Watson and Maurice Wilkins in 1962 for the elegant description of the structure of our helical molecule, Francis Crick dedicated his life towards the studying of the mind. Although I knew this true genius dedicated his life on this, I haven't got the opportunity to read about his work on consciousness before, so I was really excited when I found this book the other day.

Consciousness is a fascinating memoir, written by Christof Koch, about his rese

Here's a neuroscientist who wrote The Quest for Consciousness: A Neurobiological Approach, trying to explain how brain can give rise to consciousness. It doesn't look like he's even managed to convince himself. While you can always find a "neural correlate" for any sensory or mental or emotional experience, it's still a puzzle how neural and synaptic activities result in subjective conscious experiences. It's what philosophers refer to as the Hard Problem. Invoking an ethereal soul to explain th ...more

One cannot mention Koch without including Francis Crick---as they go together like Matzo and ball. Though too many to name here, the accolades of this author would fill a twelve-page CV. In brief, Koch taught at California Institute of Technology and elegantly vibrates our silvery web like tangle of the mind with the question, what is consciousness? He equates the brain to a psychic experience having a plus or minus one charge.

Christoph Koch is one of the leading scientists studying consciousness at a fundamental level. He has studied under the brilliant Francis Crick, is the lead scientist at the Allen Brain Institute in Seattle, and teaches at Cal Tech. A large portion of the book deals with the theory of a colleague of Koch's named Guilio Tononi. Tononi holds that consciousness is integrated information, a measurable property of causal systems that may exist in both biological and non-biological systems, e.g. compu ...more

I liked it very much. Some of it was very entertaining. In a few places, I just felt lost. An excellent discussion of free will, however, and that's a difficult topic. I'll probably reread that chapter.

My favorite paragraph:

"If we honestly seek a single, rational, and intellectually consistent view of the cosmos and everything iin it, we must abandon the classical view of the immortal soul. It is a view that is deeply embedded in our culture; it suffuses our songs, novels, movies, great buildin

Philosophers, theologians, and scientists have debated the questions of human consciousness for a very long time. What is the difference between my brain and my mind? Are my thoughts simply epiphenomena arising glibly from the chemical soup of the grey matter behind my skull walls, or do they spring divinely from my eternal soul or from some sort of ethereal akashic records?

These are daunting issues, but Christof Koch is well-qualified to tackle them as a scientist who worked alongside one of th

It's very hard to categorise or summarise this book. It works as an introduction to the field of neuroscience - particularly to the concepts involved, as opposed to this-bit-of-brain-then-that-bit-of-brain - it also has elements of speculative science; memoir and philosophy. Perhaps most affectingly, however, it is a surprisingly emotional grappling from a man who knows than almost everyone about how the brain works, yet loses himself in grief and guilt just the same. A man who understands how f ...more

The reading of all good books is like a conversation with the finest minds of past centuries.
-Rene Descartes


The subject of the book is an age old conundrum that has preoccupied scientists,philosophers and mystics alike for over many millenia- How does the water of biological tissue become the wine of conscious perception? How can the inanimate rumblings of neurons cause feelings as diverse as love, fear, anger or existential angst? Do lower life forms possess that same apparatus as us to perceiv

I started reading this book because of my connection to the Allen Institute. This is more of an autobiography and memoir than actual details about his integrated information theory and his vision for the future. Koch admits he has a flamboyant personality and that certainly shows in his writing, which makes the book interesting to read, but sometimes hard to decode. He covers many popular neuroscience discoveries (like Jennifer Aniston neurons and the Libet experiments) that may be a boring revi ...more

Chapters 6,7,8 are five-star material. The book is too full of things like this: "in 1995, Francis and I published a manuscript in the international journal Nature...(Having your article appear in Nature is like having the premier gallery in New York or Paris display your art; it's a big deal.)" In the chapters not numbered 6,7, or 8, these punchable offenses so outweigh anything of note that I only can selectively recommend the book. I was looking for Ernst Mayr, and I got a middle-aged dude st ...more

I was interested in this book because the title seemed appealing. I basically wanted to know the author's take on the 'Hard problem' of consciousness. Here, I was satisfied. Although a through reductionist, Koch admits the 'limit of reductionism' and claims that consciousness is something fundamentally different from matter and can never be fully reduced to matter. His attempt to gap the bridge between mind and matter is 'Integrated information theory', which is sort of a metaphysical theory wit ...more

Another intriguing approach to explain consciousness as a physical phenomenon, and dismissal of the idea of a mind-body duality, or the idea of classical free-will. The only thing I found abrupt was the unjustified connection between quantum mechanics and unpredictability of many brain and other biological phenomenon. There are far more macroscopic ways to explain unpredictability based on regular chaos theory. Most biological systems are complex enough to display chaotic non-linear behavior, an ...more

Listened to this :)

A great book that that does not contain that sort of self-indulgent Saganesque natural prose, despite its generic title.

Neuroscience has re-paradigmed consciousness research, snatching it from rationalistic philosophers.

Wow. What a rich, heady read! I appreciated how humble and down-to-earth Koch was throughout, emphasizing that we don't have all the answers (yet!). The most meaningful revelation was in the final chapter, which reminded me that having the capacity to contemplate humanity does not spare me from being one.

The writer is a passionate empiricist who strongly believes that the Hard Problem of Consciousness can be resolved through scientific means. He doesn't actually say how in this book, but he emphasises this belief several times.

The text is very easy to read and is peppered with the right amount of geeky humour that most people would appreciate. It's also well-structured and can be read even by those without any background knowledge in philosophy. One possible drawback to the book is the inclusion

The book is oozing personality.

This is the most daring science book I've read since Max Tegmark's Our Mathematical Universe. Yet Koch seems a man with a lot on his heart and little time.

It is a short tour de force through the scientific understanding of consciousness, a succinct presentation of his preferred hypothesis and how he plans to test it, and a brief confession about his motivations and beliefs for the future of consciousness, all in the form of confessional writing. Yup, it's a pretty

Though Koch presents a lot of solid scientific material here, the real heart of the book is the man himself and his outlooks on a series of questions that have haunted much of the history of philosophy and, more recently, science: What is consciousness, how does it work, does it require a spiritual explanation and presence or is it a mechanical construct of the human brain?

Koch, as a scientist of the modern age, not surprisingly leans heavily toward the idea that consciousness can emerge from t

To me, this is a very important book, less because of its content and more for its form. The book certainly serves as a useful and up-to-date introduction to consciousness studies from a leading scientist in the field, but its real force comes from the personal nature of the writing. Science, for good reason, is meant to be third-person, objective, and impersonal. But many scientists are themselves deeply driven to the work they do. Koch lays bear these deeper sides of scientific work and throug ...more

When I attended the Human Brain Mapping conference this year, I saw a man wearing red pants and a purple vest. I thought, what a character. He was later introduced as Christof Koch, a German-accented man with a flair to be different and the author of the book on consciousness I had recently began. Koch does a good job of introducing many concepts related to the study of consciousness, but this book is more autobiographical than didactic. I found his prose surprisingly but refreshingly honest.

This is one of the best reads in recent months. It covers thoughts about my favorite topic for lifetime: consciousness and the Brain!
The author gives a detailed view of how science has approached the problem, what theories are on plate. He also covers metaphysical aspects as well as a little bit of religious viewpoints. One of the most interesting parts was how quantum mechanics can change the way we consider free will or determinism in terms of human nature.

Beautifully tragic in his personal life in belief and personal failings. Christof's perserverance in his philosophical and scentific quest for knowledge is worth admiring and given credit to. He has illuminated life's biggest questions on consciousness and with it, the inevitable slayer of that spark. A good insightful read.

The question of what is "consciousness" has troubled philosophers for centuries. When I was an undergraduate in the philosophy department at UC Berkeley in the early 90s, John Searle was famously working on the issue --and guess what? He is still plugging away at it! And, it's not just philosophers either. Scientists also tackle the problem of reconciling a conscious, aware mind with a physical brain. According to them, consciousness emerges from chemistry and electricity in our brains. But how ...more

More than anything it was the title that prompted me to read this, which neatly encapsulates the major two ways I feel about consciousness and related topics. On the one hand, a materialist to the core (though whether I feel reductionist or non-reductionist changes from time to time), on the other hand someone who hears the call of notions defying his own materialistic positions, but despite finding them intriguing and fascinating, always falls back on those.

Woaaa...another unputdownable book about brain, mind and consciousness, written by the neuroscientist who worked closely with Francis Crick (Nobel Prize Winner; British molecular biologist, biophysicist, and neuroscientist).

The greatest of all existentialist puzzles is why there is anything rather than nothing. Surely, the most natural state of being—in the sense of assuming as little as possible—is emptiness. I don’t mean the empty space that has proved so fecund in the

The main conviction of the author is that evolution breeds complexity, and complexity breeds consciousness. There isn't a specific neural region of the brain that creates the effects of consciousness, but rather it arises as a byproduct of neuronal connectivity. Just as a single molecule of H2O doesn't have wetness property, in similar fashion a single neuron doesn't have any consciousness. Consciousness arises from the interconnectivity of neural connections.

The subject has often haunted me in the middle of countless contemplations about the big questions. Luckily a romantic reductionist could give me some insights and wisdom on it. As a neurologist who dedicated his career to focus on this very subject he explained some recent scientific findings arround the matter. But what I value the most is how Koch combines objective scientific views with his own subjective honest reflections. I find it beautiful how he, as a scientist, shares his personal vie ...more

I think the only reason I felt I had to give it four stars rather than five is that it doesn't actually contain a fully comprehensive neuroscientific theory of consciousness. Which is kind of unreasonable of me. It's just that it's written in such a way that it almost leads you to expect one, even though you know in advance that won't be happening. Anyway there's a ton of interesting info, it's a good layman' state-of-the-nation on the topic, it's written well, and the last chapter is an unexpec ...more

“It was only as a mature man that I became mortal.
The visceral insight of my end came to me abruptly more than a dozen years ago. I had wasted an entire evening playing an addictive, firstperson shooter video game that belonged to my teenage son—running through eerily empty halls, flooded corridors, nightmarishly twisting tunnels, and empty plazas under a foreign sun, emptying my weapons at hordes of aliens pursuing me relentlessly. I went to bed late and, as always, fell asleep easily. I awoke abruptly a few hours later. Knowledge had turned to certainty
—I was going to die! Not right there and then, but someday.
...
My interpretation of this queer event is that all the killing in the video game triggered
unconscious thoughts about the annihilation of the self. These processes produced sufficient anxiety that my cortico-thalamic complex woke up on its own, without any external trigger. At that point, self-consciousness lit up and was confronted with its mortality.”
