The team at Duke University fitted the rats with an infrared detector wired up to microscopic electrodes that were implanted in the […]

Pictures in nature seem to consist of sets of repeated patterns which help the human mind “see” and distinguish objects from each other. It is like Nature has its own “error correcting” mechanism. These building blocks are used by the brain so as to filter out “noise” that occurs naturally on the retina.  And it […]
