  Take this with a huge grain of salt, but I remember hearing once that the eyes are kind of an external piece of the brain.

    The Retina Wikipedia page seems to agree with you:

    In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue.

      Doing some further reading and there should be nerves present for all of our senses.

      You can argue that this representation is what a human really looks like beneath our meatsuit. If you could keep it alive and gave it a mechanical body it not only contain all the same persons thoughts and feelings but with proficient hardware also full sense of senses.

      Is that why these look like daleks?

        Sure. It all kinda has to connect to the brain somehow, or our naturally occurring meat suit wouldn’t work either, lol. But i think your proposed “adapters” may have to do more postprocessing of the signal for some senses more than for others:

        In vertebrates, the CNS also includes the retina and the optic nerve (cranial nerve II), as well as the olfactory nerves and olfactory epithelium. As parts of the CNS, they connect directly to brain neurons without intermediate ganglia.

        Which kinda makes me think we should put a nose on the image in the post, while we’re at it.

        But i’m also just reporting back from a Wikipedia rabbit-hole. I don’t really know much at all about anatomy.
