<br>I am confused. I agree with statements that the visual sense tends to be the highest bandwidth (most bits/s). But there are only 3 receptors -- everything else is subjective interpretation (as color blind or color variant people are able to discuss). On the other hand sound and smell would seem to offer much more refined senses. In sound I believe that the location of the perception is allowing different frequency differentiation while in smell one is dealing with different types of receptors, their quantity, location, etc. I would tend to relate sound to overall "touch" sensation. Its "where" the stimulation is perceived that counts.
<br><br>But in terms of overall variety, in humans, it has to be sight < taste < hearing < smell < touch. Touch wins out on the basis of larger surface area and mutiple sensors (heat, pain, pressure, etc.).<br>
<br>Now, whether ones brain is able to percieve the subtlties of these differences may depend on ones exposure when one was young and whether there was an incentive to develop those perceptual abilities. (Unused neural components tend to atrophy.)
