The spine an antenna
The spinal cord acts like an antenna to receive electromagnetic fields, according to researchers from California.
From their modelling, the scientists concluded that the spinal cord conducts external fields, with maximum effect observed in the FM radio band at approximately 100 MHz. At that frequency, the internal fields were sufficiently strong to potentially affect the central nervous system and breach the blood-brain-barrier.
