Every second awake, signals from our environment of one kind or another are converted into electrical currents (of ions—called action potentials) by sensory receptors in the skin or by special senses (like smell, vision, and hearing).
These currents, bearing no obvious resemblance to the information they carry, travel into the brain via nerve fibers (cables, if you like), and there somehow the information is decoded.
*The original signal is interpreted so that a person sees the world in vivid color, hears the sound of a waterfall, experiences the heat of a hot summer’s day, feels a breeze on the skin, and smells the barbeque.
And this can happen all at the same time;....
Q: How does the brain do this?
No one knows, but it must involve signal processing way beyond our current understanding."
