So I've been making some drawings on my iPad. I started playing with my cool new Pencil stylus and by habit I drew a few neurons. Then started adding some color splotches, and then digitally cutting up the image and rearranging them. This lead to more doodling, this time following connectivity schemes of specific neural circuits and then overlaying some of them on collages made from drawings from Cajal and other classic neuroanatomists. It's a bit hard to have much control on an iPad mini, but it works OK. I've been posting a few of them on Twitter, but I figure it's be fun to share some of them here. A sort of "Handbook of Neural Circuits".
Here's one of my favorites, it's based on the circuitry of the olfactory bulb, which is responsible for sorting, organizing and relaying olfactory information from the olfactory epithelium to the rest of the brain. The underlying image is actually a drawing from Camillo Golgi, Cajal's colleague and rival. Hope you like it!
