| 451298b | This world extends beyond this room, Adele. There are the streets of Vienna and beyond that Europe and beyond that a globe in space in orbit around a star in a universe. But how do I know that for sure? I cannot see the globe spinning on its axis right now as I speak to you. How can I be sure? I can be sure because it's logical; the mathematics is sound and respected by the orbits of the planets. I can verify it's true, not by looking at it.. | Janna Levin | ||

| 4640754 | That is this world. Figures of flesh and figures of air. It is unruly how they mingle and in fairness, Adele, in fairness, it is not always so easy to distinguish what is real from what is not. But beyond this world is another." With this his goggles steamed and his own eyes stormed with salty pebbles that beaded on his lashes. "There is another world of pure logic. There are no particles or grit or dirt or poison. There are perfect triangl.. | Janna Levin | ||
| 6537fa3 | In addition, there's a whole universe full of electromagnetic energy, radiation that somehow seems to be both waves in an electromagnetic field and particles at the same time. It exists in a spectrum of wave-lengths that includes cosmic rays, gamma rays, X rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves.Together, electromagnetic fields and energies interact in many complex ways that have given ris.. | Robert O.

| cf85254 | We now know (see Chapter 6) that at least some types of cells can revert completely to the primitive state and that such despecialization is the major, probably the only, way a blastema forms in complex animals like a salamander. | Robert O. Becker | ||
| 09523dc | In the worms and fish, there was only one area of positive potential, just as there was only one major nerve ganglion, the brain. In humans the entire head and spinal region, with its massive concentration of neurons, was strongly positive. The three specific areas of greatest positive potential were the same as in the salamander: the brain, the brachial plexus between the shoulder blades, and the lumbar enlargement at the base of the spina.. | Robert O. Becker | ||
| 4a1b922 | Space osteoporosis may result from unnatural currents induced in bone by a spacecraft's rapid motion through the earth's magnetic field, with a polarity reversal every half orbit, or it may be a direct effect of the field reversal. This abnormality, which may change the activity of bone cells directly, would be superimposed on abnormal responses of bone's natural electrical system, which is almost certainly affected by weightlessness. The u.. | Robert O. Becker | ||
| 6f2953c | Fortified by our new knowledge that electricity controlled growth in bone, we returned instead to the nerves, taking a closer look at how their currents stimulated regrowth. | Robert O. Becker | ||
| b948cf3 | By this time we'd also cleared up several more cases of osteomyelitis by reversing the battery and making the silver electrode positive for a day. It looked safe. There was no crossover of effects: When negative,the wire didn't make infectious bacteria grow, and when positive, it didn't destroy bone-forming cells or prevent them from growing when we switched the current to negative. | Robert O. Becker | ||
| 7114d63 | Like all other injuries, a fracture produced a current of injury, in this case derived from the nerves in and around the periosteum.* At the same time, the bone generated its own current piezoelectrically due to residual stress in the mangled apatite-collagen matrix. These signals combined to stimulate the cells that formed new bone. | Robert O. Becker | ||
| 7ace4d9 | All vertebrates except mammals have nuclei in their red blood cells.In mammals, these cells go through an extra stage of development in which the nucleus is discarded. The resulting cells are smaller, can flow through smaller capillaries, can be packed with more hemoglobin, and thus can carry oxygen and carbon dioxide more efficiently. | Robert O. Becker | ||
| 1055720 | All worthwhilemedical research and every medicine man's intuition is part of the samequest for knowledge of the same elusive healing energy. | Robert O. Becker | ||

| 95484c6 | Behind every dish there is death, and people only close their own eyes to it. | Alex Atala | ||
| 39e976e | Conversely, I believe low-current silver electrodes stimulate bone formation directly--by dedifferentiating the marrow cells and perhaps also by stimulating the periosteal cells. | Robert O. Becker | ||
| 13490a4 | One of the main lessons of bioelectromagnetism so far is that less is often more. | Robert O. Becker | ||
| 0731394 | The frequency of these brain waves has been crudely correlated with states of consciousness. Delta waves (0.5 to 3 cycles per second) indicate deep sleep. Theta waves (4 to 8 cycles per second) indicate trance, drowsiness, or light sleep. Alpha waves (8 to 14 cycles per second) appear during relaxed wakefulness or meditation. And beta waves (14 to 35 cycles per second), the most uneven forms, accompany all the modulations of our active ever.. | Robert O. Becker | ||
| bcd0049 | 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. | Robert O. Becker | ||
| be89bbc | The evidence to date indicates that PEMF works byincreasing the mitotic rate of the healing cells, not by altering calciummetabolism. If so, it can't possibly discriminate between bone-healingcells and any other type. It will accelerate the growth of any cellularsystem that is actively growing; this includes not only healing tissues,but fetal and malignant tissues as well | Robert O. Becker | ||
| 3e66e04 | Electrical osteogenesis could be the opening wedge into a new era of medicine. Within a few years, we may know how to use these techniques to repair joint cartilage, or even replace whole joints, and to correct various defects of bone growth. In the further future, we may be able to extend regeneration as needed to nearly all human tissues. For the first time a physician can now direct nature, albeit in a small way,rather than play her help.. | Robert O. Becker | ||
| 7375be3 | This was the start of a long friendship. I'm deeply indebted to Chester Yntema for his encouragement. Had he not believed that research should be fun, that you should do what you want rather than what's fashion-able, my first experiment would have been impossible, and this book would never have been written. | Robert O. Becker | ||
| b6c753d | Information, and a monumental amount of it, is clearly passed from the body to the blastema. | Robert O. Becker | ||
| 2fa7245 | The question of how this information is transferred is one of the hardest problems ever tackled by scientists, and when we fully know the answer, we'll understand not only regeneration but the entire process of growth from egg to adult. For now, we had best, as biologists themselves have done, skip this problem and return to it after addressing some slightly easier ones. | Robert O. Becker | ||
| 2ecf5d7 | It seems reasonable that understanding what comes out of the blastema would be easier if we understood what goes into it, so the other major questions about regeneration have always been: What stimulates the blastema to form? And where do its cells come from? | Robert O. Becker | ||
| a50ad88 | The DNA-RNA apparatus isn't the whole secret of life, but a sort of computer program by which the real secret, the control system, ex-presses its pattern in terms of living cells.This pattern is part of what many people mean by the soul, which somany philosophies have tried to explicate. However, most of the pro-posed answers haven't been connected with the physical world of biology in a way that offered a toehold for experiment. Like many .. | Robert O. Becker | ||
| 41b512f | However, the morphogenetic field no longer has to account for every-thing. Acceptance of dedifferentiation lets us divide regrowth into two phases and better understand each. The first phase begins with the cleanup of wound debris by phagocytes (the scavenger race of white blood cells) and culminates in dedifferentiation of tissue to form a blastema. Redifferentiation and orderly growth of the needed part constitute the second phase. Simpli.. | Robert O. Becker | ||
| bd4a354 | The pituitary hormone prolactin, the same substance that stimulates milk flow in nursing mothers, seems to sensitize cells to electric current. Then the signal causes nearby cells to dedifferentiate and form a blastema, apparently by changing the way cell membranes pass calcium ions. | Robert O. Becker | ||
| 3b655a2 | I believe that cuisine is the most important link between nature and culture. | Alex Atala | ||
| 6072598 | Now we saw that when you put motor and sensory nerves together into a reflex arc, the current flow formed an unbroken loop. This solved the mystery of what completed the circuit: The current returned through nerves, not some other tissue. Just as Gerard had found in the brain,nerves throughout the body were uniformly polarized, positive at the input fiber, or dendrite, and negative at the output fiber, or axon. We realized that this electri.. | Robert O. Becker | ||
| ac1a141 | Sinyukhin began by cutting one branch from each of a series of tomato plants. Then he took electrical measurements around the wound as each plant healed and sent out a new shoot near the cut. He found a negative current--a stream of electrons--flowing from the wound for the first few days. A similar "current of injury" is emitted from all wounds in animals. During the second week, after a callus had formed over the wound and the new branch .. | Robert O. Becker | ||
| 00a1676 | If the current controlled the way nerves worked in the brain as well as in the rest of the body, then it must regulate consciousness to some extent. | Robert O. Becker | ||
| 9be61dc | We tranquilized a salamander lightly, placed it on a plastic shelf be-tween the poles of a strong electromagnet, and attached electrodes to measure the EEC As we gradually increased the magnetic field strength, we saw no change--until delta waves appeared at 2,000 gauss. At 3,000 gauss, the entire BEG was composed of simple delta waves, and the animal was motionless and unresponsive to all stimuli. Moreover, as we decreased the strength of .. | Robert O. Becker | ||
| e296e37 | My only contribution was to point out that the enclosure had been built before anyone knew about the earth field's low-frequency components, micro pulsations ranging from less than 1 to about 25 cycles per second, that were far weaker than the planet's electromagnetic field as a whole. Consequently Beischer's subjects were still exposed to a very weak magnetic field pulsing at these frequencies, and I suspected that that component might be .. | Robert O. Becker | ||
| 6401867 | 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 anesthe.. | Robert O. Becker | ||
| 5f641ce | The electrical forces turned the key that unlocked the repressed genes. | Robert O. Becker | ||
| 4df7469 | This experiment demonstrated unequivocally that there was a real electric current flowing along the salamander's foreleg, and it virtually proved that the current was semiconducting. In fact, the half-dozen tests I'd performed supported every point of my hypothesis. | Robert O. Becker | ||
| d620851 | Burr and Lund advanced similar theories of an electrodynamic field,called by Burr the field of life or L-field, which held the shape of anorganism just as a mold determines the shape of a gelatin dessert."When we meet a friend we have not seen for six months there is notone molecule in his face which was there when we last saw him," Burrwrote. "But, thanks to his controlling L-field, the new molecules havefallen into the old, familiar patte.. | Robert O. Becker | ||
| 6abfa8c | Even after Marsh and Beams proved Weiss wrong in 1946, it took many more years for the scientific community to accept the fact that neuron fibers do orient themselves along a current flow. Today the possible use of electricity to guide nerve growth is one of the most exciting prospects in regeneration research. | Robert O. Becker | ||
| 8a4f213 | The motor activities we take for granted--getting out of a chair and walking across a room, picking up a cup and drinking coffee,and so on--require integration of all the muscles and sensory organs working smoothly together to produce coordinated movements that we don't even have to think about. No one has ever explained how the simple code of impulses can do all that. Even more troublesome are the higher processes, such as sight--in which .. | Robert O. Becker | ||
| 0a2ee4a | 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. | Robert O. Becker | ||
| 8438838 | Only one research team followed up this work, some ten years later.Sidney Goldring and James L. O'Leary, neuropsychiatrists at the Wash-ington University School of Medicine in St. Louis, recorded the same DC potentials from the human scalp, from the exposed brain during surgery, and from the brains of monkeys and rabbits. As noted before,the potentials varied in regular cycles several minutes long, like a basso continuo under the EEG. In fa.. | Robert O. Becker | ||
| 7a3fb2b | All the experiments led to one unifying conclusion: The overall structure, the shape, the pattern, of any animal is as real a part of its body as are its cells, heart, limbs, or teeth. Living things are called organisms because of the overriding importance of organization, and each part of the pattern somehow contains the information as to what it is in relation to the whole. The ability of this pattern to maintain itself reaches its height.. | Robert O. Becker |
