[QUOTE="Deamiter, post: 10183441, member: 17635"] Brains don't actually emit any kind of wave like that. It's actually not a wave in a physical sense. [b]It is only called a brain wave because the activity in the different types of brain waves is pretty periodic. [/b] As Philosoft said, it is only a measurement of electrical activity, or the sum of all the electrons emitted by neurons in the brain. Nothing actually gets outside the brain except some rogue electrical signals that are picked up by electrodes in an EEG (again as Philosoft said). There is a very minute magnetic field as with any electrical current, but it is so small that it is very difficult to measure -- especially outside the body! I assume that you were wondering about telepathy (since you asked about transverse/longitudinal) and waves that are emitted, but I can assure you that there is nothing emitted by the brain except for this tiny magnetic field. If telepathy truly existed (based on these magnetic fields), the magnetic field from a person standing next to you would be washed out a million times by the magnetic field in your home! In essence, the label 'wave' is a bit of a misnomer. Brain waves are waves the same way that a clock is a wave. They both have regular patterns, but neither gives off any sort of physical disturbance that is normally called a wave in physics. [/QUOTE]
