Israeli researchers discovered the existence of tiny calcite crystals in the human pineal gland. The crystals are very similar to the otoconia (also crystals) in the inner ear, indicating that they too may be able to generate tiny amounts of electric charge. If this proves to be the case, they could interact with external electromagnetic fields such as those produced by mobile phones. Any interaction could interfere with pineal gland activity, such as the production of melatonin, which is known to protect the body against a wide range of diseases as well as regulate several body cycles (e.g. sleep/wake).

Further research is needed. If the above is confirmed it will constitute a previously unknown mechanism by which extremely low level microwave fields could affect brain function.

Ed.- In depth research by Bristol University's Professor Dennis Henshaw unearthed nine studies suggesting that low level electromagnetic fields reduce the pineal gland's production of the hormone melatonin. Melatonin regulates many biological rhythms, including the sleep cycle, and is thought to protect against a range of illnesses, including cancer.
