Toad Visual Neurons

Weekends are for internet rabbit holes: watching Jurassic Park (for the millionth time) and discovering some really interesting research on how toads see. Above are stills from a video by researcher Jörg-Peter Ewert, testing how toad neurons react to various worm-like stimuli. (Warning, the video includes some images of lab animals.)

The pattern testing, and subsequent neural network, seem very relevant to computer vision work today (bonus for day-glo yellow too).
