Normally the human brain swings between alpha waves and beta waves. But sometimes lambda waves are thrown off. Rarely, very rarely, the lambda variant. It was discovered during research on E S P and other paranormal powers of the human mind." Brain electrical activity includes alpha, beta, theta and delta waves. They are not transmitted in any way (it is just internal activity within the brain). No-one has yet found any evidence of ESP (telepathy or mind reading), let alone an associated wave pattern.
