Sunita Williams Quotes

The mental act of sensation which issues in reflex movement is so simple as to defy analysis.

Replacing human vision is more than just a tool: we need to understand how that affects the brain.

The same regions of the brain light up when someone touches their smartphone as when they touch a family member or a pet.

We see in the electroencephalogram a concomitant phenomenon of the continuous nerve processes which take place in the brain, exactly as the electrocardiogram represents a concomitant phenomenon of the contractions of the individual segments of the heart.

Interestingly enough, not all feelings result from the body's reaction to external stimuli. Sometimes changes are purely simulated in the brain maps.

When you look at the brain regions associated with picking up data from the body, a huge amount of the brain is devoted to picking up information from the lips and tongue.

We will move from looking at correlations between brain activity and behaviour to studying how the brain causes mental states and behaviour.

Our ability to perceive the world around us seems so effortless that we tend to take it for granted.

The amount of sensory material stored up or stored down in the brain's and the body's systems is inestimable. It's like a culture at the bottom of a jar, although it doesn't grow, I think, or help anything else to grow unless you find a way to reach it and touch it.

It turns out our brain is sensitive, maybe too sensitive, to motion. It's a survival mechanism.

All our behaviours are a result of neurophysiological activity in the brain.

He who feels compelled to consider the consequences of these facts cannot but realize that the specific sensibility of nerves for certain impressions is not enough, since all nerves are sensitive to the same cause but react to the same cause in different ways.

Neuroscience has proven that similar areas of the brain are activated both in the person who suffers and in the one who feels empathy. Thus, empathic suffering is a true experience of suffering.

Light comes to us by the sensibility. Without visual sensibility there is no light, no movement.

All our behaviours are a result of neurophysiological activity in the brain. There is no reason to believe there is any magic going on.

The brain is a complex biological organ possessing immense computational capability: it constructs our sensory experience, regulates our thoughts and emotions, and controls our actions.

Space and time, not proteins and neurons, hold the answer to the problem of consciousness. When we consider the nerve impulses entering the brain, we realize that they are not woven together automatically, any more than the information is inside a computer.

We're told that when we remember, the same parts of our brain light up as when we experienced the event we're remembering. Your brain lives through it again.

It is exceedingly improbable that the identical action of the corresponding parts of the two retina is the result of a certain habituation, or of the influence of the mind.

It must be born in mind that one does not see directly - as is the case in the exploration of the surface of the brain - where the electrodes are attacking.

The discovery of the habit loop is important because it reveals a basic truth: When a habit emerges, the brain stops fully participating in decision making. It stops working so hard, or diverts focus to other tasks.

Animal vision - including human vision - is so biased toward movement that we don't technically see stationary objects at all.

The brain, which is plastic when young, must be exposed to certain sights early in life, or it will remain blind to those sights forever.

The thing you realize when you get into studying neuroscience, even a little bit, is that everything is connected to everything else. So it's as if the brain is trying to use everything at its disposal - what it is seeing, what it is hearing, what is the temperature, past experience.

The brain is such an incredible computer.
