Quotes & Sayings About Brain Stimulation

These were "fossil behaviors," Darwinian vestiges of earlier times brought out of physiological limbo by the stimulation of primitive brain-stem systems, damaged and sensitized by the encephalitis in the first place, and now "awakened" by L-dopa.1 I — Oliver Sacks

Man does not have the right to develop his own mind. This kind of liberal orientation has great appeal. We must electrically control the brain. Some day armies and generals will be controlled by electrical stimulation of the brain. — Jose Manuel Rodriguez Delgado

Given her deafness, the auditory part of the brain, deprived of its usual input, had started to generate a spontaneous activity of its own, and this took the form of musical hallucinations, mostly musical memories from her earlier life. The brain needed to stay incessantly active, and if it was not getting its usual stimulation ... , it would create its own stimulation in the form of hallucinations. — Oliver Sacks

Exercise has a direct brain connection, when you consider what it actually does. What we tend to overlook are the feedback loops that connect the brain to every cell in the body. Therefore when you throw a ball, run on a treadmill, or jog along the shore, billions of cells are "seeing" the outside world. The chemicals transmitted form the brain are acting the way sense organs do, making contact with the outside world and offering stimulation from that world.
This is why the jump from being sedentary to doing a minimal amount of exercise - such as walking, light gardening, and climbing the stairs instead of taking the elevator - is so healthy. Your cells want to be part of the world. — Deepak Chopra

British researchers found that one smile can generate the same level of brain stimulation as up to 2,000 bars of chocolate. The same study found that smiling is as stimulating as receiving up to 16,000 pounds Sterling in cash. That's like 25 grand a smile. — Ron Gutman

Multitasking has been found to increase the production of the stress hormone cortisol as well as the fight-or-flight hormone adrenaline, which can overstimulate your brain and cause mental fog or scrambled thinking. Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation. To make matters worse, the prefrontal cortex has a novelty bias, meaning that its attention can be easily hijacked by something new - the proverbial shiny objects — Daniel J. Levitin

The infant needs to develop sufficient muscle tone in order to be able to move around and stimulate this linking together. To establish tone, the infant needs to be touched, hugged, and rocked, as well as being allowed to move around freely. Such stimulation sends signals from the sense organs of the tactile, balance and kinaesthetic senses to those centres of the brain stem that regulate muscle tone. If the baby gets insufficient stimulation from these senses the tone of the extensor muscles will be low.3 This may make it difficult for the baby to lift his head and chest and move around, further reducing the stimulation from the balance, tactile and kinaesthetic senses, leading to a particularly vicious cycle of developmental delay. — Harald Blomberg

In the traditionally taught view of perception, data from the sensorium pours into the brain, works its way up the sensory hierarchy, and makes itself seen, heard, smelled, tasted, felt - "perceived." But a closer examination of the data suggests this is incorrect. The brain is properly thought of as a mostly closed system that runs on its own internally generated activity. We already have many examples of this sort of activity: for example, breathing, digestion, and walking are controlled by autonomously running activity generators in your brain stem and spinal cord. During dream sleep the brain is isolated from its normal input, so internal activation is the only source of cortical stimulation. In the awake state, internal activity is the basis for imagination and hallucinations. — David Eagleman

He thinks he's happy but it's just a nerve cell in his brain that's getting too much stimulation or too little stimulation. — Don DeLillo

What the brain does by itself is infinitely more fascinating and complex than any response it can make to chemical stimulation. — Ursula K. Le Guin

What about self-awareness, the mysterious ability of the brain to reflect upon itself? Self-awareness can be tampered with by brainwashing, psychoactive drugs, electrical stimulation, political or religious propaganda, even advertising. A lifetime in front of a TV set may be the equivalent of a self transplant. — Chet Raymo

The connections in the brain fade away unless used. We know that early stimulation of children leads to higher cognitive scores. — Brian Sutton-Smith

Researchers would eventually discover that autistic people stim to reduce anxiety - and also simply because it feels good. In fact, harmless forms of self-stimulation (like flapping and fidgeting) may facilitate learning by freeing up executive-functioning resources in the brain that would otherwise be devoted to suppressing them. — Steve Silberman

Texting is addicting. Once you get emotionally involved with constant outside stimulation assaulting your brain, it is hard to stop looking at your machine every two minutes. Without rapid fire words appearing on a screen, you feel bored, not part of the action. — Bill O'Reilly

Such epileptic hallucinations or dreams, Penfield showed, are never phantasies: they are always memories, and memories of the most precise and vivid kind, accompanied by the emotions which accompanied the original experience. Their extraordinary and consistent detail, which was evoked each time the cortex was stimulated, and exceeded anything which could be recalled by ordinary memory, suggested to Penfield that the brain retained an almost perfect record of every lifetime's experience, that the total stream of consciousness was preserved in the brain, and, as such, could always be evoked or called forth, whether by the ordinary needs and circumstances of life, or by the extraordinary circumstances of an epileptic or electrical stimulation. — Oliver Sacks

We need a program of psychosurgery for political control of our society. The purpose is physical control of the mind. Everyone who deviates from the given norm can be surgically mutilated ... The individual may think that the most important reality is his own existence, but this is only his personal point of view. This lacks historical perspective. Man does not have the right to develop his own mind. This kind of liberal orientation has great appeal. We must electronically control the brain. Someday armies and generals will be controlled by electric stimulation of the brain. — Jose Manuel Rodriguez Delgado

If you stimulate seizures in an animal every day, the seizures eventually become automatic; the animal will go on having them once a day even if you withdraw the stimulation. In much the same way, the brain that has gone into depression a few times will continue to return to depression over and over. This suggests that depression, even if it is occasioned by external tragedy, ultimately changes the structure, as well as the biochemistry, of the brain. — Andrew Solomon

More recently, these electrodes have targeted a new area of the brain (called Brodmann's area number 25) that is often overactive in depressed patients who do not respond to psychotherapy or drugs. Deep brain stimulation has given almost miraculous relief after decades of torment and agony for these long-suffering patients. — Michio Kaku

I do not know how much a propensity to addiction is "hardwired" or how much it depends on circumstances or state of mind. All I know is that I was hooked after that night with an amphetamine-soaked joint and was to remain hooked for the next four years. In the thrall of amphetamines, sleep was impossible, food was neglected, and everything was subordinated to the stimulation of the pleasure centers in my brain. — Oliver Sacks

I bailed out on social media for a while, and in short order I found I was able to sit down and read a book again. For the first time in a couple years I could read more than three pages without my brain wandering off into the ether. I drew a direct causal line between all this sort of ratta-tat-tat staccato stimulation that we get from the Internet and my growing inability to sit down and read anything that was longer than 500 words. But for me it came back because those synapses were already latent in my brain. — Ron Currie Jr.

Sex becomes less and less pleasurable in a relationship over time. Your brain gets habituated to the sensual stimulation from your specific partner as you are exposed to it repeatedly. It doesn't mean that the love is gone from the relationship. Love still exists beyond the barriers of time, in the form of attachment, which becomes independent of sexual intimacy after the euphoric stage of mad love. — Abhijit Naskar
