Could there be brain wave frequencies that we haven't detected?

Easily, the brain is vast and in reality we don't know much about it.

We're limited by our imagination & what we can detect by our senses or tools

I belive if you are really close to someone sometimes (as corny as it sounds) you have similiar brain wave patterns and can tap into each other thoughts.  I had that experience a lot with my best friend.  It is eerie but very cool too!

We can never know how another species thinks, let alone another person.  We can only make assumptions based on similar brain activity (using MRIs, CT scans, and EEGs) among individuals.  For example, we can see different regions of the brain are more active during the REM stage of sleep, when people experience dreaming.  We can see the same brain regions active in other animals when they are sleeping, so we therefore come to the conclusion that they are dreaming. (transitive property, I think)

No, because psychokinetic energies transmit on a frequency outside of the parameters of an audio recording device.\n\nSome older analog systems will capture psychokinetic frequencies, but unless the equipment is precisely calibrated within the Brown frequency range, phase cancellation will occur which can cause severely attenuated psychokinetic effects, if not complete chi-inversion.

Precognition.  Its not that rare.  Can't proven to be a ral occurance.  But could be.

You mean like an electroencephlogram (EEG).

With the debunking that Houdini did in his time I would not take mediums and psychics very seriously.  But, given that the FBI and other law enforcement agencies use psychics occasionally there is something to it.  I believe that we have senses that we're not able to identify yet, but that it's more scientific than supernatural.  Things such as sensing someone is watching you from across the room, or having a bad feeling at the time someone you care about is in trouble.  Those things do happen, and can't be explained, so we put it into a Supernatural category until there's a scientific explanation.  I believe its some sort of network, and the animal world has examples of this type of communication, but we have yet to understand.

I'm a neurosurgeon. I don't think anyone will be able to give a satisfactory answer to that question, in large part because we don't have any meaningful units of measurement. \n\nWe can't use "bytes" like in a computer. We can't determine how many "facts" someone knows. We might be able to work out reaction speeds etc. but we can't really pin down how many other things you are thinking of at the time and how that might influence it; we can't sort out how many people you know or what your total vocabulary is really; or how many slightly different scents you can recognize.\n\nMost of the time, we are unaware of the thousands of pieces of information we are constantly processing unconsciously, like air temperature, sounds around us, colour of text on screen, clock ticking, feel of socks on our feet, hair on our neck. We may notice out of the corner of our eye that our co-worker has gotten up; her unhurried walk and the smell of cappucino indicate that it's coffee break rather than an emergency evacuation, and our brain doesn't even consciously notify us of making the decision to stay at our desk.\n\nThe brain can process massive amounts of information very quickly - you are actually doing complicated calculus every time you catch a flying ball! - but we don't have a good way to quantify it.

Kyle, if you can figure this one out, you best write a very long book about it. Science has been working on this for a long time. Obviously, the cerebral cortex has something to do with it, but not all. Awareness, specificially self-awareness, is a slippery fish. I will not give you Wikipedia links, you probably already have them.\n\nRather, look up Julian Jaynes and his work on the Bicameral Mind. Early work but interesting. He thought that once upon a time the two halves of our brains were not very interconnected, that we received messages from the right half as mystical experiences, shamanic insight. The books he wrote are incredibly hard to read. \n\nI will see what else I can dig up for you. Great question. The work on this is ongoing.

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.

Slow your mind. Modern life tends to wind us up; literally speeding up our brainwave frequency. Normal daily, wide-awake, states of consciousness are Beta frequency 14 up to 20+ cycles per second. Beta level brainwave activity is too fast to allow psychic connections. Beta brain is a busy brain so the practice of meditation and relaxation methods you are comfortable with are the first steps to develop psychic ability.

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. ^_^

Over everything else, our brains are pattern recoginition machines.  They are very, very good at filling in blanks -- even if they shouldn't.  The usefulness of this comes when coupled with our reasoning ability to figure out if things are important illusions, i.e. if the sabre-toothed tiger went around that side of the rock, he didn't just disappear, he's probably also coming out on the other side... but he can't see me right now either.

Being I've had them, I assume they are common. As far as "astral projections" are concerned, I can't imagine they could be verified in any rigorous or scientifically adept way...at least at this time. Have you read much about "remote viewing?" There has been some notable experiments carried out in this area for which I see some correlations.  Your last comment about the third moon of Saturn seems a bit "tongue 'n cheek" which makes me wonder if you're not a major skeptic. That's okay, 'cause I am too... I just try to keep an "open mind."  Entertaining any GUTS theory tends to have that effect on you.

There are many things that we do that do not require our conscious brain.  Whatever things you are talking about, perhaps the subconscious got started on it before the consciousness got involved.  When cockroaches feel stimulus on their back legs, they begin running before their conscious mind knows why they are running.  It's just like the other poster said, the impulse telling your hand to pull oout of a fire doesn't require your conscious mind to make a decision, it starts the process for you.\n\nIt's an interesting idea that this might have to do with quantum wierdness, but I think experiments woudl reject that.  I encourage you to keep thinking of things like this and hypothesizing.  Eventually you may be teaching us instead of the other way around :-)

I have known a few people who have had head injuries. It basically depends on what part of the brain is injured. I would suggest finding a book or website that shows you the different areas of the brain to see what functions could be impaired. You can also ask his doctor or his family to try to get the answer. Good luck, and I hope he's ok.
