A third-year medical student named Liggett at the University of Miami received a psychiatric patient who claimed to hear radio music playing in his head. This 18-year-old veteran was quite surprising to Liggett. Upon further examination, it was discovered that the patient had shrapnel in his head from the Vietnam War. Although the sounds were sometimes unclear, he could identify the music, news, and advertisements being broadcast. Liggett had the patient try tuning in, ultimately confirming that the radio signal was coming from Miami's WQAM station. So, why does the brain emit radio sounds? A biologist in the U.S. speculated that biochemical substances within the skull might react with the metal shrapnel, similar to the aluminum crystals found in transistor radios from 50 years ago. This phenomenon reveals the complex connection between the brain and the external world, prompting reflection on the limitless possibilities of the human brain.
