Quotes About Brain

a mind is a brain that is conscious.

Tal y como dice el neurocientífico del MIT Sebastian Seung, "la identidad no depende de nuestros genes, sino de las conexiones entre nuestras células cerebrales" (

Ultimately our brains, combined with the technologies they have fostered, will permit us to create a synthetic neocortex that will contain well beyond a mere 300 million pattern processors. Why not a billion? Or a trillion?

we each appear to have two brains, not one, and we can do pretty well with either.

Work by physiology professor Benjamin Libet at the University of California at Davis shows that neural activity to initiate an action actually occurs about a third of a second before the brain has made the decision to take the action.

Furthermore, neurons are extremely slow; electronic circuits are at least a million times faster. Once a computer achieves a human level of ability in understanding abstract concepts, recognizing patterns, and other attributes of human intelligence, it will be able to apply this ability to a knowledge base of all human-acquired—and machine-acquired—knowledge.

Stephen Hawking recently commented in the German magazine Focus that computer intelligence will surpass that of humans within a few decades. He advocated that we "urgently need to develop direct connections to the brain, so that computers can add to human intelligence, rather than be in opposition."25 Hawking can take comfort that the development program he is recommending is well under way.

you create your brain from the input you get.

In order for a digital neocortex to learn a new skill, it will still require many iterations of education, just as a biological neocortex does, but once a single digital neocortex somewhere and at some time learns something, it can share that knowledge with every other digital neocortex without delay. We can each have our own private neocortex extenders in the cloud, just as we have our own private stores of personal data today.

By failing to engage it in intellectually challenging activities, your brain will fail to grow new connections, and it will indeed become disorganized and ultimately dysfunctional. The converse is also true for both body and brain. If someone who has not been physically active for a sustained period starts a program of physical therapy and regular exercise, she can regain her muscle mass and tone within a matter of months. The same thing is true of your brain.

From a biological perspective, motivation is a process that "determines how much energy and attention the brain and body assign to a given stimulus—whether it's a thought coming in or a situation that confronts one

The extent of neuromanic imperialism is astounding.

The errors of muddling correlation with causation, necessary condition with sufficient causation, and sufficient causation with identity lie at the heart of the neuromaniac's basic assumption that consciousness and nerve impulses are one and the same, and that (to echo a commonly used formulation) "the mind is a creation of the brain".

I am now going to argue that neuroscience does not address, even less answer, the fundamental question of the relation(s) between matter and mind, body and mind, or brain and mind. If it seems to do so this is only the result of a confusion between, indeed a conflation of, three quite different relations: correlation, causation and identity.

The linguistic habit that has kept so many in thrall to Neuromania is referring to the brain and bits of the brain in ways that would be appropriate only if we were referring to whole human beings.

But even those who locate the roots of consciousness in the brain should still recognize that brains together create a space that cannot be stuffed back into the brain.

Trying to discover the contents of our ordinary Wednesdays in the tropisms of the evolved organism as reflected in brain activity is like applying one's ear to a seed and expecting to hear the rustling of the woods in a breeze.

Is a concussion going to lead to CTE? No, probably not in most cases. But if you have enough concussions over a certain amount of time, yes, then I think you can lead to CTE.

I'm lucky: I've got great photogenic eyes. You're up and running if you've got that and one brain cell to attach it to.

It's interesting how sleepwalking in a certain way becomes an accumulation of your outside stimuli that's actually there and what's happening in your brain.

If you could access 90 percent of your brain, you'd be Charles Xavier.

My head is massive. My head is, like, off the charts.

If you don't work your brain turns to cheese.

I'm very anti-antidepressants. It's not the chemicals of my brain that's a problem; it's reality. I don't think tricking my brain into reinterpreting reality is going to help.
