Brent,
So it is the neurotransmitter that causes the experience? What is the
function of the neurotransmitter? It is absorbed by the dendritic synapses
and it is converted back to a spike train. I already explained this. It is
like the sound in the air when somebody talks to you. Your ear responds to
the presence of vibrating air but this vibration is converted into spike
trains! The air is just a medium to communicate information. It is not what
matters. How does the presence of neurotransmitter helps us better
understand redness? You never tried to explain this. Because to you they
sound more "material" than spike trains?
