Imagine two identical tuning forks in one room.

When one tuning fork is hit with a little hammer it produces a sound which can be received by the other tuning fork. The receiver tuning fork starts to oscillate because it is in resonance with the sound transmitting tuning fork.

This behavior is not only true for tuning forks. Actually any identical objects can be used as transmitters and receivers!

This means that two identical molecules can be used by the brain to transmit and receive information. The transmission is just using electromagnetic waves instead of sound.

Now we put several tuning forks into the room and repeat the experiment. When we hit the transmitter all other tuning forks will start to oscillate. Its like a radio station that can be heard at many places.

From a data processing point this is very important. Every receiver immediately receives the signal and can process it under different aspects. In computer terms this is called parallel processing. For the brain this means that an image from the eye can be used immediately for comparison in the smell center, in the hearing center and other senses to identify an object.

With our current tuning fork arrangement we can only hear one tone - or in other words one frequency. To hear speech we must be able to hear several tones - or frequencies.

A range of frequencies is also called a bandwidth. We can increase the bandwidth of our arrangement by using several sets of tuning forks.

The brain uses a similar arrangement. The sound goes into the ear where it is split into different frequencies. Each frequency signal is then attached to a nerve which transports the signal to a brain cell. The brain cell contains a transmitter molecule which starts oscillating and sends a radio signal to identical receiver molecules in other brain cells responsible for the recognition of the signal.

To increase the resolution ( bandwidth ) of the ear nature separates the sound frequencies in the cochlea of the ear. It is the snail like form of the cochlea that makes this possible. Inside the cochlea there are heaps of little plates each connected to a nerve responsible for one frequency.

These nerves are now fed into a brain cells which have all different transmit frequencies.

Now the brain can transmit complex sound images to any part in the brain where it is needed. The brain cells that need to process the sound just have a string of resonators called a resonator chain which contains copies, or near copies of the transmitter molecules.

The other senses work on the same principle. In computer terms any pattern is called an image. The brain deals with visual images, images of sound, images of smell etc....
