There's the question of top-down processing versus bottom-up processing. Are our brains the CPU where all the signals are received and processed? Or perhaps do some of our organs process some of the signals?
In my opinion, our organs do a bit of processing before sending to the brain.

A lot of information is already consolidated in our retinas before being piped to the visual cortex, and some dinosaurs developed secondary brains to deal with predators biting their tails. It doesn’t make sense to transmit raw data to the brain to have it consolidated there, but there will be some issues with the peripheral nervous system dropping important information (maybe optical illusions or auditory hallucinations fall into that category).
