NO

radio signals depend on two frequencies

radios and human brain --> very different things

how do radio's work resonance -->receive different frequencies and due to resonance we hear audio when the frequency of radio,station is same

how the *** can brain decipher/change its natural frequency

our ears have a range of 20Hz to 20KHz so now how does ear work :

Sound waves travel through the outer ear, are modulated by the middle ear, and are transmitted to a nerve in the inner ear, the vestibulocochlear nerve. This nerve transmits information to the temporal lobe of the brain, where it is registered as sound.

Sound that travels through the outer ear impacts on the tympanic membrane (ear drum), and causes it to vibrate. The three ossicles transmit this sound to a second window, the oval window, which protects the fluid-filled inner ear. In detail, the pinna of the outer ear helps to focus a sound, which impacts on the tympanic membrane. The malleus rests on the membrane, and receives the vibration. This vibration is transmitted along the incus and stapes to the oval window. Two small muscles, the tensor tympani and stapedius, also help modulate noise. The tensor tympani dampens noise, and the stapedius decreases the receptivity to high-frequency noise. Vibration of the oval window causes vibration of the endolymph within the ventricles and cochlea.

The hollow channels of the inner ear are filled with liquid, and contain a sensory epithelium that is studded with hair cells. The microscopic "hairs" of these cells are structural protein filaments that project out into the fluid. The hair cells are mechanoreceptors that release a chemical neurotransmitter when stimulated. Sound waves moving through fluid flows against the receptor cells of the Organ of Corti. The fluid pushes the filaments of individual cells; movement of the filaments causes receptor cells to become open to the potassium-rich endolymph. This causes the cell to depolarise, and creates an action potential that is transmitted along the the spiral ganglion, which sends information through the auditory portion of the vestibulocochlear nerve to the temporal lobe of the brain.

how to change ear's natural frequency

Short answer is "no". Radio signals are transmitted in packets of information that are beyond the ability of the brain to collect and decipher. It would be like a blind person trying to read a foreign language that they could not understand.

Although I know exactly what you mean about getting a song "stuck in your head", I'm afraid this is just a coincidence =/

Analogue radio transmissions have (supposedly) been known to be "detected" (i.e. converted into audio frequency signal currents) that cause audible vibrations: specifically - in tooth fillings.





However, I have not heard of any example in which the brain has caused similar signal currents to be experienced as sounds that can be recognized.





Quote: " Can brain pick up radio signals? ..."



.....my answer to your specifc question is "No, I do not think it can".

No, it is definitely not possible, and even if it were your brain couldn't "translate" the signals into a song.

Songs aren't recognizable to humans through electromagnetic radiation. They're recognized through soundwave patterns.

If that were possible you would be spasming out on the floor having a seizure.

No.

Okay, this might sound like a crazy theory or complete randomness.. But how many times have you had a song stuck in your head only to turn on the radio and find the same song playing?

My question, is it possible for the brain to pick up radio signals? The brain and body is made up of water and carbon which are conductors of electricity so is it even remotely possible for the brain to somehow be able to pick up on the radio signals? I know it sounds ridiculous and probably is. Because that would mean the brain would need to not only pick up the signal but have a means to decipher the signal and play it back. I have the comical vision of a person opening their mouth and songs coming...

Likely just a random coincidence but something I've always wondered about since a child.
