Complexity Of The Brain Quotes & Sayings

He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire. — Greg Iles

If we ever find out how the brain works, with all its complexity, then we will be able to build a machine that has consciousness. And if that happens, that is a road to planetary disaster because everything we've thought about ourselves, since the Bronze Age, the Bible, all of that will be gone. — E.L. Doctorow

The brain seems to be made up of a bewildering complexity of parts, and the cells within the parts seem to be characterized by an inscrutable complexity of form, extent, and relationships with each other. — Gordon Shepherd

The tape measures and weighing scales of the Victorian brain scientists have been supplanted by powerful neuroimaging technologies, but there is still a lesson to be learned from historical examples such as these. State-of-the-art brain scanners offer us unprecedented information about the structure and working of the brain. But don't forget that, once, wrapping a tape measure around the head was considered modern and sophisticated, and it's important not to fall into the same old traps. As we'll see in later chapters, although certain popular commentators make it seem effortlessly easy, the sheer complexity of the brain makes interpreting and understanding the meaning of any sex differences we find in the brain a very difficult task. But the first, and perhaps surprising, issue in sex differences research is that of knowing which differences are real and which, like the intially promising cephalic index, are flukes or spurious. — Cordelia Fine

Coffee has ... expand[ed] humanity's working-day from twelve to a potential twenty-four hours. The tempo, the complexity, the tension of modern life, call for something that can perform the miracle of stimulating brain activity, without evil, habit-forming after-effects. — Margaret Meagher

However, we have the benefits of the billions of years of evolution that have already taken place, which are responsible for the greatly increased order of complexity in the natural world. We can now benefit from it by using our evolved tools to reverse engineer the products of biological evolution (most importantly, the human brain). — Ray Kurzweil

There are no inherent barriers to our being able to reverse engineer the operating principles of human intelligence and replicate these capabilities in the more powerful computational substrates that will become available in the decades ahead. The human brain is a complex hierarchy of complex systems, but it does not represent a level of complexity beyond what we are already capable of handling. — Ray Kurzweil

He also found he made mistakes in handling complexity. A good decision requires looking at so many different features of companies in so many ways that, even without the cocaine brain, he was missing obvious patterns. His mental checklist wasn't good enough. "I am not Warren," he said. "I don't have a 300 IQ." He needed an approach that could work for someone with an ordinary IQ. So he devised a written checklist. — Atul Gawande

It's the old idea that the process of evolution is some push in the direction of greater complexity
in particular greater intellectual complexity. In one twig of the tree of life, namely ours, having a big brain happened to have advantages. But that's just what worked for a particular species of primate 5 to 7 million years ago. — Steven Pinker

The complexity of the resulting signalling network in the brain is almost unimaginable: one hundred billion neurons each with one thousand synapses, producing a machine with one hundred trillion interconnections! If you started to count them at one per second you would still be counting 30 million years from now! — Michael O'Shea

I don't think there was a thunderclap or a divine spark that suddenly made one species smart. You can see, in our ancestors, there was a gradual expansion of the brain; there was an expansion of the complexity of tools. — Steven Pinker

Compared to the complexity of the universe, this world of ours is like the brain of a worm. — Haruki Murakami

Psychiatry, as a subspecialty of medicine, aspires to define mental illness as precisely as, let's say, cancer of the pancreas, or streptococcal infection of the lungs. However, given the complexity of mind, brain, and human attachment systems, we have not come even close to achieving that sort of precision. Understanding what is "wrong" with people currently is more a question of the mind-set of the practitioner (and of what insurance companies will pay for) than of verifiable, objective facts. — Bessel A. Van Der Kolk

Biology doesn't know in advance what the end product will be; there's no Stuffit Compressor to convert a human being into a genome. But the genome itself is very much akin to a compression scheme, a terrifically efficient description of how to build something of great complexity-perhaps more efficient than anything yet developed in the labs of computer scientists (never mind the complexities of the brain, there are trillions of cells in the rest of the body, and they are all supervised by the same 30,000-gene genome). And although there is no counterpart in nature to a program that compresses a picture into a compact description, there is a natural counterpart to the program that decompresses the compressed encoding, and that's the cell. Genome in, organism out. Through the logic of gene expression, cells are self-regulating factories that translate genomes into biological structure. — Gary F. Marcus

It is unmatched in its ability to think, to communicate, and to reason. Most striking of all, it has a unique awareness of its identity and of its place in space and time. Welcome to the human brain, the cathedral of complexity. — Peter Coveney

The Internet is dumb. The Internet, with all its access to brain research, anthropology journals, social studies networks, and biographies and autobiographies, can't begin to map the complexity of our lives, or how we each affect others. — Dee Williams

the brain of a child learning a language can cope with a mind-boggling amount of linguistic complexity. — Guy Deutscher

Does anything show the complexity of the miraculous brain more than that weird curiosity, the sleep-protection dream? — Dick Cavett

The brain immediately confronts us with its great complexity. The human brain weighs only three to four pounds but contains about 100 billion neurons. Although that extraordinary number is of the same order of magnitude as the number of stars in the Milky Way, it cannot account for the complexity of the brain. The liver probably contains 100 million cells, but 1,000 livers do not add up to a rich inner life. — Gerald Fischbach

I believe C++ instills fear in programmers, fear that the interaction of some details causes unpredictable results. Its unmanageable complexity has spawned more fear-preventing tools than any other language, but the solution should have been to create and use a language that does not overload the whole goddamn human brain with irrelevant details. — Erik Naggum

During the twentieth century, neuroscientists and psychologists also came to more fully appreciate the astounding complexity of the human brain. Inside our skulls, they discovered, are some 100 billion neurons, which take many different shapes and range in length from a few tenths of a millimeter to a few feet.4 A single neuron typically has many dendrites (though only one axon), and dendrites and axons can have a multitude of branches and synaptic terminals. The average neuron makes about a thousand synaptic connections, and some neurons can make a hundred times that number. — Nicholas Carr

Checklists turn out ... to be among the basic tools of the quality and productivity revolution in aviation, engineering, construction - in virtually every field combining high risk and complexity. Checklists seem lowly and simplistic, but they help fill in for the gaps in our brains and between our brains. — Atul Gawande

Both scientists and laypeople can find themselves seduced into the easy trap of wanting to assign each function of the brain to a specific location. Perhaps because of pressure for simple sound bites, a steady stream of reports in the media (and even in the scientific literature) has created the false impression that the brain area for such-and-such has just been discovered. Such reports feed popular expectation and hope for easy labeling, but the true situation is much more interesting: the continuous networks of neural circuitry accomplish their functions using multiple, independently discovered strategies. The brain lends itself well to the complexity of the world, but poorly to clear-cut cartography. — David Eagleman

One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world. And it seems, and not without reason, that now is the really critical moment for natural science; for the brain, in its highest complexity - the human brain - which created and creates natural science, itself becomes the object of this science. — Ivan Pavlov

An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system has evolved and functions without assistance of the brain. — Niels Kaj Jerne

Generally speaking, our minds impose an entirely artificial order on the world. It is the only way that such an inadequate instrument as our brain can function. It cannot deal with the complexity of reality, so simplifies everything until it can, putting events into an artificial order so they can be dealt with one at a time, rather than all at once as they should be. Such a way of interpreting existence is learnt, rather in the way that our brain has to turn the images which hit our retinas upside down in order to make sense of them. Children — Iain Pears
