Imagine that the inner ear can transmit data (as the silia within the choclea vibrate) via electromagnetic imprinting upon a preexisting (standing) electromagnetic field. \n \n...As electromagnetic fields allow sound to behave in a linear fashon...this environment affords a detectable imprint of the brain's reaction to a sound wave produced within this field....as we all know, our brain's produce electromagnetic output.\nexpound upon this.  Please help me in trying to figure out how to Finnish a project that I am working on!

Both a radio and an ear respond logarithmically. A doubling of sound (3DB) will give a barely perceptable increase in the sound we hear,\nSame is true of am RF radio wave

No, but you can see the effects of sound. Sound is a wave, like radio waves, microwaves etc... Sound can be recorded and the intensity of it can be graphed to show the effects.

This has to do with the wonderful sensory apparatus at our fingertips.\nThe skin of the nail beds is exquisitely supplied with densely packed nerve endings, including many pain endings (as torturers of every era have always discovered). This is partly to give us the very high degree of haptic (touch) sensitivity we enjoy in our finger tips and partly to help ensure that we take extra special care of these wonderful, survival-enhancing manipulative instruments.\nResearchers have shown that there are some high-threshold nociceptors among these intertwined nerve endings in the skin; i.e., receptors that respond almost exclusively to tissue-damaging stimuli. Many of the rest, however, are "polymodal" receptors and nerves that signal other haptic modalities by combined (cross line) *patterns* of responses in many adjacent receptors and their connecting neural pathways. That is presumably why you can get funny effects like a strong burning sensation by placing a rack on the skin that has slightly-spaced alternating cold (but not painful) and warm (not hot) bars. The brain interprets this pattern of stimulation as intense burning, even though it's a totally innocuous stimulus.\n\n\nRunning your fingernail down the board causes a pattern of high frequency microvibrations in the nail, much like blowing on a clarinet reed causes sound vibrations. (Think about the ugly sounds the chalk makes when a careless lecturer hits the board at a bad angle). I suspect these vibrations of the nail are transferred to the dense net of nerve endings beneath the nail where they do some mischief within the touch system--it's quite an unphysiological stimulus, i.e., unlike the sort of stimuli the system usually encounters in everyday life. What we have learned from phenomena such as the "phantom limb" is that any unphysiological, random pattern of impulses in parts of this polymodal network is likely to be interpreted by the brain as noxious and that is what is happening in this instance.\nAn interesting experiment would be to try to recreate this pattern of stimulation to the nailbed in the laboratory using microvibrators instead of a blackboard, to see how people would react. It might be hard to get volunteer subjects, though, and one can only imagine what the ethics review panel would say!\n \nThe question asks why listening to that sound is irritating. The answer explains why making the sound is irritating. It seems likely that the response would be a result of preventing physical damage. If it was a response in the nerves of the fingertips, it would affect only the person making the noise, but as most everyone has experienced, the sound of fingernails scraping a chalkboard is painful to everyone within earshot. The response probably comes because the frequency of the sound is similar to the sound created by damage to the human body. Perhaps the chalkboard sound is like the sound of bones breaking, specifically the type of break that would come from jumping off of something too high to safely jump off of. Moreover, the slip and stick motion is similar to the feeling of teeth scraping together, or teeth being scraped by something too hard to chew. Perhaps the reaction comes from the need to preserve one's teeth for eating meat.

This newpaper article states what I have been saying for years (and my mother before me RE: transistor radios).\n\nhttp://www.hearinglossweb.com/discus/messages/11/807.html?SundayMarch1920060829am

EDIT: Half of my answer didn't post for some reason.\n\nScientists have been studying this for years, but never have found an answer.\n\nWhen I spoke to a deaf woman about this idea, this is what she said: "When I think about what I am going to say, I think about it in sign and I sometimes sign in my sleep.  However, when I read something (because there is no written version of sign language) I think about it in English.  Concepts are created visually more often than in English."\n\nFor an actual study, when presented with a stimulus, the visual and language areas of the brain become active, whereas in a hearing person, the auditory and language areas of the brain become active.  While they are processed differently, the language area of the brain is used at all times.\n\nThe only other help I can offer is a study on Genie, a girl who was locked up and unsocialized until about the age of twelve.  While she was able to be somewhat rehabilitated and learn some basic vocabulary, she never figured out how to put complex sentences together, which was thought to show she was not capable of complex thought.  However, the data was compromised because it was thought that she may be mentally challenged.

(jesus H pogostick, another redneck using "The Bible" as a source for a rather useless "because God said so" answer to a serious scholarly question)\n\nThe brain doesn't "know", that's just the way it works. The way the image is formed in the eye is immaterial - every child that's born learns to make sense of the nerve impulses arriving at it's visual cortex all by itself without knowledge of the system supplying those impulses.\n\nYou could just as well ask how the brain knows to turn signals coming from various points along the cochlear apparatus (where soundwaves of different lengths resonate across it) into discrete, conciously perceived "tones", or those from different sensory nerves into touches, injuries and temperature (etc) perceived to come from various (occasionally incorrect - e.g. stiff neck headaches) body parts.\n\nA fish knows nothing of the water in which it swims, but it still natigates around well enough and "breathes" it without realising it's breathing a concentration of dissolved O2 in HOO (dihydrogen monoxide). Same is true for the brain. It just tweaks it all about until the world makes sense.\n\nIt's all tied in with conciousness and "the minds eye". Despite my opening statement, this is one area it's still ok to have some mysticism in as we simply don't know what causes it (other than the worryingly easy and seemingly sensible, but homonculus-baiting "its your immortal soul looking outwards")\nBut its gonna be fun finding out.

Well, i don't know for sure either,\n\nbut i've been reading in some books that telling about an experiment by turning a Classical music and a Heavy Metal music beside a plant (the same species of plants with the same caring), it turns out that the plant with classical music was grow healthy and gave a good fruit, while the Rock plant kind of skinny and don't even gave any fruit, and die slowly.\n\nI never seen it by myself, but i think it's logical that the sound wave (wich is energy) somehow bringing some kind of information (or effecting by force) to the plant (life being) and effecting the life of the cell...\n\nI haven't really make a research on this anyway, i have another project right now...\n\nHope this help\nBless You

Your first paragraph is quite true. Tesla patented various methods for transmitting power using large resonators with local "receivers."  If you have a resonant cavity you can get pretty good coupling between source and receiver (microwave oven for example).  The general use for power distribution has its problems, not least of which is how do you charge($) the receiver?\n\nThe analogy of sympathetic vibration is valid.\n\nNot sure what to make of the magnetism bit.\n\nElectrons resonate - they may in fact be "resonances"\n\nOur entire electrical power system is based on Electricity and Magnetism so I think the answer is yes we can pick up energy.\n\nWhat may be missing is that we also have to provide the energy up front before we get to pick it up!

There is a theory stating that the universe can be composed of information.  However, transmitting an object through a network or a cable means that you have to "transform" the object´s atomic structure and make it compatible with the format and bandwith of the means you are using to transmit it.  Theoretically it is possible (like in the movie "The fly"), but current science has still its limitations about it.

I assume you're talking about the things measured by an electroencephalogram: they are, actually, electrical current, after all.\n\nThe tricky bit is that the voltages and amperages are incredibly small: microvolts and milliamps.  Slim pickings, energy wise!\n\nConversely, implanted electrodes are used in brains--mainly in non-human brains, for research purposes, but slowly we're doing a few useful things with the electrodes in humans--and their electrical activity triggers neurons to fire, creating, indeed, brain waves.\n\nDon't hold your breath on using brain energy to power much of anything, nor on using electrical stimulation to produce coherent sensory experience other than triggering memories and a handful of other small change things: we're quantum leaps away from that, still.

Well, double-helix galaxies have been spotted in space, just do a search for it.  They are shaped by magnetic fields and enormous Birkeland  currents.  This should give us an idea about what purpose our DNA serves, and what the  connection between the small molecule chain and the galaxy is.\n\nWe're enormously complex creatures, but there should be no doubt that the consciousness is located in the various energy fields of the body.  Ancient lore handed down from the ages taught us this, and it should have finally been proven when science found that currents travel our nerves all around our body and create storms in our brain.\n\nEarth has a natural electric field, and where do you think your soul will exist when you die?

Since your ears are separated from each other by a fixed distance, one ear generally receives the signal before the other one does.  Depending upon the differential between the two, your brain computes the angle from which the sound originates.  If both hear it at the same moment, it is coming from directly ahead or behind.

There are two answers to this question:  one, how the waves themselves propogate and two, how the wavefront moves.  \n\nTo answer the first there are two things to remember:\n1.) a changing magnetic field creates an electric field\n2.)likewise, a changing electric field creates a magnetic field\n\nWith those two things in mind, here is how an EM wave (of which light is just one type) propogates.  A changing electric field induces a magnetic field, which induces an electric field and so on as the wave moves.  In other words one creates the other to move the disturbance along and the fields "bootstrap" themselves forward.\n\nAs to the second part, the way the wavefront moves depends on the geometry of what you're looking at.  If you imagine a source out in space, then yes you could consider the wavefront as being a sphere whose radius increases at the speed of light (for a repeated signal, then you'd have concentric spheres, one wave for each time the object sends out a pulse).  However if you restrict the wave to move in something (e.g. a waveguide, or channel)  the wave fronts would look different.\n\n\nI hope that helps

This is a very interesting topic. It's like how you can hear yourself say something in your mind, but you don't actually hear sound. Or how you see a certain image when your eyes are open (hence, daydream). It's difficult to observe thoughts as they are happening, since the only way to actually formulate an opinion about what we are thinking is to analyze what we remember thinking. It's pretty amazing how our minds work, and what they control. We can't (more accurately, MOST of us can't) voluntarily control the rate of our heart beat, but we can voluntarily control our breathing. Yet, when we are asleep or not paying attention, our brain's nervous system takes over. It's so amazing...\n\nI can go on about this forever! : ) I actually have never heard of the Heisenberg Uncertainty principle but I'll look into it. (After a pause...) My thoughts are telling me to finish typing. ^_^

That effect is real and the explanation is very simple: it's our ears detecting tiny sound reflections from the surrounding environment. Around us there is always noise, although we may not perceive it consciously. But when our forehead is close to a reflecting surface, we perceive those tiny echoes, even if we are blindfolded.\nIt's a very rough version of what bats do all the time.

Technically, it would be possible, but likely very delicate.  Experiments are underway to assists people with disabilities, and look promising, but the control is done with very coarse setting like "thinking about talking" and "thinking about moving the foot", so that very distinct area of the brain are involved, so that they are easily distinguished in operation. To go beyond that, and be able to control very delicate instrument with high precision like it was one own limb would probably require going in and tapping the nerves directly; picking up the signal though the thickness of the skull and homing to an area that is measured in millimeter -- let alone singling out one neuron -- is asking too much.

Ha ha ha. The question is weird unless you are referring to something specific in physics. Otherwiss,\n\nLike Patient who lies down on bed, remains on bed because of gravity :)\nOr Simple stuff like - the stethoscope lets you hear the heart beat because of physical principals of sound movement.
