The human brain is at particularly high risk for damage by free radicals because of its high degree of metabolism compared to other tissues, while lacking the levels of antioxidant protection found elsewhere in the body.
Neuroscience is by far the most exciting branch of science because the brain is the most fascinating object in the universe. Every human brain is different - the brain makes each human unique and defines who he or she is.
All of imagination - everything that we think, we feel, we sense - comes through the human brain. And once we create new patterns in this brain, once we shape the brain in a new way, it never returns to its original shape.
You need to have a lot of human judgment involved in the financial industry in terms of risk management, in terms of investment decisions, and things that really allow us to blend the best of technology and the human brain.
Everything we do, every thought we've ever had, is produced by the human brain. But exactly how it operates remains one of the biggest unsolved mysteries, and it seems the more we probe its secrets, the more surprises we find.
Clearly, the inhabitants of stable democracies find it hard to appreciate what they have: 'You don't know what you've got 'til it's gone' isn't just a song lyric; it's an expression of something fundamental about the human brain.
Our ancestors relied upon their advanced brains to survive during times of food shortage, and fortunately, the human brain is able to utilize body fat as an extremely efficient fuel to sustain function when glucose-providing food is unavailable.
Nobody really knows what it would take to create something that is self-aware or has a personality. I guess I could imagine a day when perhaps, if we can understand how it works in the human brain, which is unbelievably complicated, it could be possible.
Schools still operate as if all knowledge is contained in books, and as if the salient points in books must be stored in each human brain - to be used when needed. The political and financial powers controlling schools decide what these salient points are.
The human brain had a vast memory storage. It made us curious and very creative. Those were the characteristics that gave us an advantage - curiosity, creativity and memory. And that brain did something very special. It invented an idea called 'the future.'
The human brain long ago evolved a mechanism for rewarding us when we encountered new information: a little shot of dopamine in the brain each time we learned something new. Across evolutionary history, compulsively seeking information was adaptive behavior.
The human brain works as a binary computer and can only analyze the exact information-based zeros and ones (or black and white). Our heart is more like a chemical computer that uses fuzzy logic to analyze information that can't be easily defined in zeros and ones.
The biggest invention of modern time is the book. The book is a digital medium; book text is written in a different form and replicable. What it really does is it allows us to replicate cultural information, scientific technology, and information out of the human brain.
Story was that human civilization started to develop with first social network. Emerged where population concentration was high. Helped propel to where we are now. Facebook is next step of creating a huge human brain to embrace hundreds of million, possibly billions of people.
Melody is the single most important thing to any song, period. I don't care what anybody says, it trumps everything. Not because that's my opinion but because I think it's actually indisputable fact. The human brain retains melody easier than it retains words. It's that simple.
I have always been convinced that the only way to get artificial intelligence to work is to do the computation in a way similar to the human brain. That is the goal I have been pursuing. We are making progress, though we still have lots to learn about how the brain actually works.
I'm enormously interested to see where neuroscience can take us in understanding these complexities of the human brain and how it works, but I do think there may be limits in terms of what science can tell us about what does good and evil mean anyway, and what are those concepts about?
Vulcan Inc. is a unique organization that unites commercial, philanthropic, research, policy, and technology innovation. Our goals are ambitious - from saving Africa's elephants to unlocking the secrets of the human brain to building sustainable communities and opening up access to space.
The human brain is a product of natural selection. In the face of scarcity, our hominid great-great-uncles were unable to compete against our sapient great-great-grandparents' abilities to build more elaborate mental models and orchestrate their bodies' movements in more sophisticated ways.
A single human brain has about a hundred million nerve cells... and a computer program that throws light on the mind/brain problem will have to incorporate the deepest insights of biologists, nerve scientists, psychologists, physiologists, linguists, social scientists, and even philosophers.
Certainly the first true humans were unique by virtue of their large brains. It was because the human brain is so large when compared with that of a chimpanzee that paleontologists for years hunted for a half-ape, half-human skeleton that would provide a fossil link between the human and the ape.
Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.
It has actually been suggested that warfare may have been the principle evolutionary pressure that created the huge gap between the human brain and that of our closest living relatives, the anthropoid apes. Whole groups of hominids with inferior brains could not win wars and were therefore exterminated.
Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function.
By 2020, most home computers will have the computing power of a human brain. That doesn't mean that they are brains, but it means that in terms of raw processing, they can process bits as fast as a brain can. So the question is, how far behind that is the development of a machine that's as smart as we are?
Natural selection shaped the human brain to be drawn toward aspects of nature that enhance our survival and reproduction, like verdant landscapes and docile creatures. There is no payoff to getting the warm fuzzies in the presence of rats, snakes, mosquitoes, cockroaches, herpes simplex and the rabies virus.
It is imperfection - not perfection - that is the end result of the program written into that formidably complex engine that is the human brain, and of the influences exerted upon us by the environment and whoever takes care of us during the long years of our physical, psychological and intellectual development.
Fifty million Americans have dementia and other brain illnesses. To gather together the minds that exist and see how we can tackle these ailments together, that is the work that is in front of us: to have a map of the human brain, an understanding of the roadways, and an understanding of the traffic on the roadways.
Some social scientists say that in-group/out-group biases are hard-wired into the human brain. Even without overt prejudice, it is cognitively convenient for people to sort items into categories and respond based on what is usually associated with those categories: a form of statistical discrimination, playing the odds.
If we study learning as a data science, we can reverse engineer the human brain and tailor learning techniques to maximize the chances of student success. This is the biggest revolution that could happen in education, turning it into a data-driven science, and not such a medieval set of rumors professors tend to carry on.
The notion of a writer sitting in a library doing research isn't what I want. The research I love doing isn't found in a book. It's what it feels like to rappel down the side of a building; to train with a SWAT team; to hold a human brain in your hands; or to dive for pirate treasure. Those are things I've done to research my stories.
I love CG - it's a great tool. I just don't think you should use it to replace reality; you should use it to augment and enhance. Do matte paintings, do composites, do replications, stuff like that, but you're taking something real and working with that as opposed to trying to fake it from scratch. The human brain can tell the difference.
I don't know if this is the flat-out strangest, but I'll never forget handling a human brain. It had been sliced into sections for autopsy, each about an inch thick, and felt like pork tenderloin. I swear to god, my first thought was that if you were to dust it with chipotle and cinnamon and saute it in butter, it would probably be delicious.
In my own life, I found that whenever I wasn't sure what to do next, I would go and learn a lot, read a lot, talk to experts. I don't know how the human brain works, but it's almost magical: when you read enough or talk to enough experts, when you have enough inputs, new ideas start appearing. This seems to happen for a lot of people that I know.
