Quotes About Electrodes

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.

We want to be like the cyborg monkey (albeit not as hairy and without the electrodes). We want that same capability to use complicated technologies without thinking about them, without experiencing them as burdens and distractions. We want our technologies to extend our minds and augment our abilities, not break up our minds.

For paralyzed people the fitting and integration of an exoskeleton was a complicated affair, they told him, stretched out over months of tests, and a certain amount of surgical fusion of electrodes and nerves. For a normal person it was much simpler. It was like a bra fitting

Moving beyond mere correlation, if you lesion the amygdala in an animal, rates of aggression decline. The same occurs transiently when you temporarily silence the amygdala by injecting Novocain into it. Conversely, implanting electrodes that stimulate neurons there, or spritzing in excitatory neurotransmitters (stay tuned), triggers aggression.4

Stick recording electrodes into numerous species' amygdalaefn9 and see when neurons there have action potentials; this turns out to be when the animal is being aggressive.fn10 In a related approach, determine which brain regions consume extra oxygen or glucose, or synthesize certain activity-related proteins, during aggression—the amygdala tops the list.

This is the pain pacemaker. I've got a battery under my skin. From that battery are two electrodes that go into the spine where they cut bone away to accommodate it. Now I put on the power here. If I have the pain, the stimulator starts. It's tingling, like when your foot falls asleep, you know?

Two separate currents, then, one from the nerves and one from the bone matrix, were producing potentials of opposite polarity, which acted like the electrodes of a battery. These living electrodes were creating a complex field whose exact shape and strength reflected the position of the bone pieces. The limb was, in effect, taking its own X ray.

The electrodes we'd been using on salamanders couldn't be scaled up for people, but within a week Charlie invented some that would give us equally precise readings from the human head.We immediately found that the back-to-front current varied with changes in consciousness just as in salamanders. It was strongest during heightened physical or mental activity, it declined during rest, and it reversed direction in both normal sleep and anesthesia.

Conversely, I believe low-current silver electrodes stimulate bone formation directly—by dedifferentiating the marrow cells and perhaps also by stimulating the periosteal cells.

The EEG provided a record of rhythmic fluctuations in potential voltage over various parts of the head. Berger at first thought there was only one wave from the whole brain, but it soon became clear that the waves differed, depending on where the electrodes were put. Modern EEGs use as many as thirty-two separate channels, all over the head.

At this time, therefore, I must conclude that high-current electrodes might enhance the growth of any preexisting tumor cells in the electrical path—unlike low-current silver, which when negative had no effect on, and when positive suspended, mitosis of cancer cells in our lab.

He sat down with great caution, after inspecting the chair for concealed electrodes, and made me the gift of his card.

In ten days' time, the police only managed to set down two pages of legal transcripts. In brief, it was an unpleasant experience. I only think back on it when I piss and I notice the whitish scars that the electrodes left on my dick.

He even experimented on himself, hammering a sleeve into his own skull. Once this was accomplished, it was then possible to insert electrodes and inject chemicals "through small needles anywhere in the brain.

The thermodynamic properties of electrolyte solutions can be determined from the measurements of the voltage between electrodes reversible to both ions.

the use of electrodes at skull sutures by a newly developed means which enabled contact to be made directly with the gray cells, without even the necessity of shaving a patch of skull.

If indeed there was an intruder in the McIntosh house, it would be deeply satisfying to apprehend him. Barb McIntosh suspected a sex offender, and, if she was right, Em knew exactly where she'd target the electrodes.

This is the pain pacemaker. I've got a battery under my skin. From that battery are two electrodes that go into the spine where they cut bone away to accommodate it. Now I put on the power here. If I have the pain, the stimulator starts. It's tingling, like when your foot falls asleep, you know?

But now all the natural secrets have been exposed, and it is likely that the turtles have been sold to laboratory scientists who want to remove their shells so that they can wire electrodes to the turtles' skin in order to monitor their increasing terror at the loss of their shells.
