I'm not sure what your question is. I'm not saying that we don't see
mental pictures, I'm saying that the pictures are not the things
being transmitted and received in the brain. Much like in a TV,
there are no pictures being send around the circuitry, there are
electrons in wires.<br>
<br>
The pictures are higher-level constructs.<br>
