I'm wondering why there are different subjective experiences when our sensor systems are technically the same neurons that just get excited by different stuff (photons, soundwaves, ...).
So why does it feel different to hear something than to see something when both are just electrical impulses?
I'm of course aware of the concept of qualia ("redness" etc.), but I haven't found this question being discussed in relation to that.
Of course I'm not claiming that the most outer part of the sensor systems work in the same way. However all of them produce (or their function results in) electrical frequencies. I highly doubt that if you'd input the frequencies produced by a retina to the neurons of an auditory system, this would result in vision.
From what I understand and know, all sensory systems output electrical signals. Apart from differing frequencies I would say they(the signals) are the same. At the same time, I doubt that it's just the frequency spectrum in an electrical system that makes a signal "vision" or "sound" to our subjective experience.
