Science is the quintessential international endeavour, and the sterling reputation of the Nobel awards is partly due to the widely-perceived lack of national and other biases in the selection of the laureates.
I want MIT to be the dream of every child who wants to grow up to make the world a better place. We need to reach those young explorers and bring them with us on the great adventure of discovery and innovation.
That daydreaming mode turns out to be restorative. It's like hitting the reset button in your brain. And you don't get in that daydreaming mode typically by texting and Facebooking. You get in it by disengaging.
You'd think people would realize they're bad at multitasking and would quit. But a cognitive illusion sets in, fueled in part by a dopamine-adrenaline feedback loop, in which multitaskers think they are doing great.
After all, across the population there are slight differences in brain function, and sometimes these translate directly into different ways of experiencing the world. And each individual believes his way is reality.
If we are to appropriate money for roads, we need statistics on how bad our roads really are and, moreover, where more roads will be beneficial - it would be irresponsible to just build them where our gut tells us to.
You need to have tremendous confidence in your work, even a touch of arrogance, chutzpah. Many very fine researchers lack intellectual daring. It's human nature to want to be cozy, secure. But that can be a cul de sac.
If you hear on the weather report that it's going to rain tomorrow, rather than reminding yourself to bring your umbrella, set the umbrella by the front door - now the environment is reminding you to bring the umbrella.
There are three deaths. The first is when the body ceases to function. The second is when the body is consigned to the grave. The third is that moment, sometime in the future, when your name is spoken for the last time.
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.
Out of 30,000 edible plants thought to exist on earth, just eleven account for 93% of all that humans eat: oats, corn, rice, wheat, potatoes, yucca (also called tapioca or cassava), sorghum, millet, beans, barley, and rye.
The rest-seeking procrastinators would generally rather not exert themselves at all, while the fun-task procrastinators enjoy being busy and active all the time but have a hard time starting things that are not so amusing.
Procrastination comes in two types. Some of us procrastinate in order to pursue restful activities - spending time in bed, watching TV - while others delay difficult or unpleasant tasks in favor of those that are more fun.
We need to support the media by subscribing to newspapers and magazines and supporting their advertisers to stay in business. And we need to be less greedy and allow journalists to take the time to pull the story together.
All life will die, all mind will cease, and it will all be as if it had never happened. That, to be honest, is the goal to which evolution is traveling, that is the "benevolent" end of the furious living and furious dying.
My views as an individual ought not to be confused with my views as a scientist - the minute you try to mingle God and science, you get into trouble. Metaphysics has its place, and science has its place; don't mix the two.
Imbalance of reason and emotion may explain the tenacity of religion in societies: world religions are optimized to tap into the emotional networks, and great arguments of reason amount to little against such magnetic pull.
Approximating involves making a series of educated guesses systematically by partitioning the problem into manageable chunks, identifying assumptions, and then using your general knowledge of the world to fill in the blanks.
Our brains are very, very good at self-delusion. What happens is, it releases the stress hormone cortisol in the brain, which leads to foggy thinking, so you're not even able to judge well whether you're working well or not.
Who we can be begins with our molecular blueprints - a series of alien codes penned in invisibly small strings of acids - well before we have anything to do with it. We are a product of our inaccessible, microscopic history.
When the brain activity is kindled in the right spot, people hear voices. If a physician prescribes an anti-epileptic medication, the seizures go away and the voices disappear. Our reality depends on what our biology is up to.
Google is a company whose very existence depends on innovation - on inventing things that are new and didn't exist before - and on refining existing ideas and technologies to allow consumers to do things they couldn't do before.
Getting new information through Web-surfing almost always feels more rewarding than having to generate new information in the work that is in front of us. It therefore takes increasing amounts of self-discipline to stay on task.
Music can be thought of as a type of perceptual illusion in which our brain imposes structure and order on a sequence of sounds. Just how this structure leads us to experience emotional reactions is part of the mystery of music.
We do not know with any of these neuropsychiatric disorders what the ultimate basis is. Let's say you could find that too much of protein X was involved in schizophrenia. Would you then know what schizophrenia is? You would not.
My mother was religious; she was knowledgeable about mythology and scriptures; she could tell the metaphysical nuances and make the story come to life with their deeper significance. The current generation is missing out on this.
What has always surprised me when I walk into a bookstore is the number of books that you can find that are written with certainty. The authors tell some story as though it's true, but they don't have any evidence that it is true!
The brain internally simulates what will happen if you were to perform some action under specific conditions. Internal models not only play a role in motor acts (such as catching or dodging) but also underlie conscious perception.
Use the environment to remind you of what needs to be done. If you're afraid you'll forget to buy milk on the way home, put an empty milk carton on the seat next to you in the car or in the backpack you carry to work on the subway.
Many of us feel as though we are overloaded and overwhelmed by all the things that are happening, and we can't stop work for even five minutes or we'll fall behind: the idea that if we don't take breaks, we're being more productive.
Each cell sends electrical pulses to other cells, up to hundreds of times per second. If you represented each of these trillions and trillions of pulses in your brain by a single photon of light, the combined output would be blinding.
The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building.
I think of the brain as a computational device: It has a bunch of little components that perform calculations on some small aspect of the problem, and another part of the brain has to stitch it all together, like a tapestry or a quilt.
There is no real independent self, aloof from other human beings, inspecting the world, inspecting other people. You are, in fact, connected not just via Facebook and Internet, you're actually quite literally connected by your neurons.
Similarly, dance is not just a raging sea of unrelated bodily movements; the relationship of those movements to one another is what creates integrity and integrality, a coherence and cohesion that the higher levels of our brain process.
In my view, the argument from parsimony is really no argument at all - it typically functions only to shut down more interesting discussion. If history is any guide, it's never a good idea to assume that a scientific problem is cornered.
Of the thousands of ways that humans differ from one another, turns out there's this one cluster of traits called conscientiousness that predict a whole host of positive life outcomes, such as longevity over our health, life satisfaction.
Two sides to a story exist when evidence exists on both sides of a position. Then, reasonable people may disagree about how to weigh that evidence and what conclusion to form from it. Everyone, of course, is entitled to their own opinion.
A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
You can use meditation, and prayer, and ritual to foster compassion, love, and inclusiveness, or you can use them to foster hatred, and exclusiveness, and anger. And it's really just a matter of what concepts, ideas you decide to focus on.
What it turns out is that we think we're multitasking, but we're not. The brain is sequential tasking: we flit from one thought to the next very, very rapidly, giving us the illusion that what we're doing is doing all these things at once.
Lofty questions about the mind are fascinating to ask, philosophers have been asking them for three millennia both in India where I am from and here in the West - but it is only in the brain that we can eventually hope to find the answers.
Healthy breaks can hit the reset button in your brain, restoring some of the glucose and other metabolic nutrients used up with deep thought. A healthy break is one in which you allow your brain to rest, to loosen its grip on your thoughts.
In our current understanding of science, we can't find the physical gap in which to slip free will - the uncaused causer - because there seems to be no part of the machinery that does not follow in a causal relationship from the other parts.
I think, though, that we need to be armed with the critical thinking skills that lawyers and scientists and journalists such as yourself have. We all need to have those as we make our way through the day. And they're not that hard to acquire.
Even while it's true that we are tied to our molecules and proteins and neurons - as strokes and hormones and drugs and microorganisms indisputably tell us - it does not logically follow that humans are best described only as pieces and parts.
I'm a simple country neuroscientist, not an expert on democracy, but I do know something about how the brain works and how opinion-reinforcing bubbles can distort the picture of reality we build from the information we encounter on a daily basis.
Constant reminding ourselves that we not see with our eyes but with our synergetic eye-brain system working as a whole will produce constant astonishment as we notice, more and more often, how much of our perceptions emerge from our preconceptions.
What the artist tries to do (either consciously or unconsciously) is to not only capture the essence of something but also to amplify it in order to more powerfully activate the same neural mechanisms that would be activated by the original object.
Workers in government, the arts, and industry report that the sheer volume of email they receive is overwhelming, taking a huge bite out of their day. We feel obliged to answer our emails, but it seems impossible to do so and get anything else done.
