No, the prediction is that as long as you have not replaced the binding neuron, nothing you present to it, will ever say and know something has a redness quality, without real redness. In other words, without real glutamate, you will not be able to throw the switch, between the simluated glutamate, and the real thing, and reproduce the behavior saying the simulated glutamate is the same as the real thing. </blockquote><div><br></div><div>### Almost all neurons are binding neurons. The neurons that construct the perception of redness are in the V4 area, and respond the same both to physiological (reflectance) and certain non-physiological (monochromator) stimuli. Redness does not exist as a property below the V4 area. Most cortical neurons have glutamatergic synapses but only V4 neurons use glutamatergic transmission to construct the quale of redness. </div><div><br></div><div>Glutamate is a transparent, easily crystallizable substance, and produces a pleasant taste when applied to umami receptors in the mouth. It has no "redness" quality. </div><div><br></div><div>Rafa</div></div>
