They don't. Human bitrates are quite low all things considered. The eyes which by far produce them most information only have a bitrate equivalent to ~2kbps:

The rest of the input nerves don't bring us over 20kpbs.
The average image recognition system has access to more data and can tell the difference between a cat and a banana. A human has somewhat more capability than that.
- lostmsu 4y agoI think the link says a single synapse does 2kbps, not the whole visual cortex. There are 6 quadrillion (10^12) synapses (3q per hemisphere) in visual cortex according to https://pubmed.ncbi.nlm.nih.gov/7244322/ https://pubmed.ncbi.nlm.nih.gov/7244322/ If we play "the bus filled with ping-pongs" with that information: it is a 3D structure so if you assume cortex is a perfect cube that feeds to something right behind it, you will get (10^12)^(2 (dimensions)/3 (of 3 dimensions)) channels, e.g. 10^8 channels 2kbps each. E.g. about 25GB/s. Which is less than an order of magnitude off from an estimate you would get from 8000x8000 resolution per eye True Color at 24fps - 9GB/s.
