Recommends it for: anyone who needs to be humbled.
This was the longest 3-month read of my life. I did finish the bastard, though. If you want to enjoy it, read chapter 1, then skip to 9. The concept is fascinating: where is the seat of consciousness in the brain, and what, exactly, is consciousness - along with a little exploration in what consciousness is for. The execution was beastly. Even with a background in anatomy, I had no idea where the author was going with about half of the book, and was pretty pissed at him when I figured it out "Yo ...more

Until recently, those interested in learning about consciousness have had just three options: (1) introspection (informative but deceiving), (2) books by philosophers (interesting but completely speculative), and (3) books by crazies (the majority of the literature on consciousness). Consciousness has long been a naughty word in science, but ho! No longer! While the "hard problem" of exactly why phenomenological states arise from the collective squirts of neurotransmitters washing across your br ...more

(3.0) Worthy goal, not sure I got much out of the book though

A noble goal: to find the neural correlate of consciousness (NCC), the network of neurons to point to as where perception 'happens'. To a neuroscientist, this is probably a tremendous amount of review. To a non-neuroscientist, probably way more neurobio than can be absorbed. But he does well to try to rule out places where consciousness cannot be (in vision, retina, V1, for example), and hints at where it might be (in vision, inferotem

أكثر من ستة أشهر قراءة بكتاب كريستوف كوتش وأفكار فرنسيس كريك مكتشف الدنا و مازال التساؤل قائم هل العالم الداخلي للأفكار والمفاهيم مخبأ دائما عن الوعي كما في العالم الفيزيائي؟!
يركز الكتاب علي الأشكال الحسية للوعي وعلي البصر خاصة أكثر من الوجوه الأخري للأحساس. يفترض كوتش وفرنسيس بأن الارتباطات العصبية للوعي تشيد علي أساس تمثيل عصبي صريح مثال صريح علي ذلك توجه اللحاء البصري الأولي أو تشفير الوجه أسفل الفص الصدغي وذلك شرط ضروري، لكنه غير كاف للارتباطات العصبية للوعي. بمعني أن الأنشطة في هذا اللحاء،

This is THE book on consciousness if you're looking for a purely neurobiological approach. The picture is still very incomplete: Koch sticks to making claims based on hard scientific evidence, and makes no assumptions. If you don't mind using a bit of analytical philosophy to make the jump and build the entire picture, I'd recommend Metzinger's "Being No One".

Light entertaining read.

النسخة العربية رغم الترجمة الممتازة والجهد الجبار المبذول فيها الا انها سيئة ! يبدو ان المشكلة في اللغة العربية ذاتها وهيمنة الانجليزية كلسان للعلوم ... ربما المشكلة في طريقة العرض خاصة في ظل وجود تجارب معقدة نسبيا كان من الممكن يتحول الكتاب لفيلم وثائقي شيق .. او يمكن المشكلة في توقعاتي وفي الوعي في حد ذاته :D

Recommends it for: Those wondering how the brain creates "consciousness"
If I could recommend just one book on a neuroscientific approach to consciousness, this would be it. But don't expect any clear answers to be spelled out for you – we’re not there yet. In particular, Koch does not provide the reader with anything approaching a satisfying explanation of how subjectivity can arise from a physical system.

A spectacular book. Koch is an excellent writer and he structures this challenging material in such a way as to make it totally accessible. He takes a stab at a topic that most neuroscientists shy away from. He makes it very clear what is grounded in evidence (most of the book) and what is speculation. Even then, his speculation follows often times directly from the evidence.

The sort of book which might inescapably alter the way that you understand your own perception of the world (at least thi

Because this book brings in real neuroscience data it is the best book on consciousness yet published. Consciousness is a combination of perception and conscious sensations called qualia, two different phenomena. Qualia is why we see the color blue instead of just blindly react to some neural signals as would zombies (we can do this up to a point in a phenomena called blind-sight which involves a primitive non-cortical neural pathway). One can have qualia without perception but not vice-versa as ...more

Christof Koch's Quest for Consciousness is intended for lay audiences, but it is still a highly technical book, about the neurobiological approach to investigating consciousness. The book is at turns highly readable and at other other turns abstruse in its use of neuroanatomical descriptions of brain regions and processes. Nevertheless, it was enjoyable to read. Koch argues that consciousness, or awareness, is an emergent property of the nervous system, important for planning and choosing among ...more

كتاب رائع يتحدث عن رحلة كريستوف كوخ لمعرفة المناطق العصبية المرتبطة بالوعي. يوجد بالكتاب الكثير الكثير من التجارب العلمية بنتائج رائعة.
دماغ الإنسان يعلم أشياءً انت بوعيك لا تعلمها. ويقوم بأمور أفضل واسرع مما تقوم بها وانت بوعيك.
Amazing book. speak about Christof Koch journey to discover Neuron correlated to consciousness. You'll find a lot of experiments with surprising results (at least for me :) ).

misleading title, should be Vision and Consciousness or something like that. quite dry and technical, but informative and occasionally very interesting.

So much neurobiology that the quest for consciousness gets lost in it.

Read an article in SciAm, was really looking for his upcoming book, but it's not in the database and I'm on mobile.

Meant to be reviewed for my senior thesis. heh. This is the continuation of work Koch did with Francis Crick on the nature of the workings of the human mind.

Absolutely fascinating.

koch worked with crick on neurobiology and the consciousness of vision. they want to define and ncc, a minimal neuronal correlate of consciousness. ok book, but not the best in the field.
