The image below is from my blog post on this topic at Brainfacts.org. Although aimed at high school level, this image is complicated. I try to explain why the “hollow face” appears to follow you as you walk about a room.
Apologies for no recent posts here. I have a few long ones in mind.
I’ve made a post at blogs.brainfacts.org describing the stepping response in newborns and discussing central pattern generators. I’ve been blogging at Brainfacts for a few weeks, and plan on writing educational posts there; I’ll be posting more broad-ranging material here. We’ll see how it works out. So far, I’ve been getting many more comments here. Comments are great.
