Real neurons are noisy: Can neural implants figure that out? The brain has adaptive noise filters that change with conditions, making signals 20 – 100 percent more accurate – Science Daily
Signals sent from the retina to the brain have a lot of background noise, yet we see the world clearly. Researchers show that to achieve visual clarity the brain must accurately measure how this noise is distributed across neurons when processing the signals …
If human eyes came in a package, it would have to be labeled “Natural product. Some variation may occur.” Because the million-plus retinal ganglion cells that send signals to the human brain for interpretation don’t all perform exactly the same way.They are what an engineer would call ‘noisy’ — there is variance between cells and from one moment to the next. And yet, when we see a photograph of a beautiful flower, it looks sharp and colorful and we know what it is.
