The Patient Who Saw Faces in Everything is one of the questions that sounds simple until you look at what the brain is actually doing. In this article we unpack the neuroscience in plain language — no jargon, no assumed background — so the mechanism becomes something you can picture.
We start with what researchers have observed, connect it to the brain systems involved, and end with what it means for how you experience everyday life. Where the science is still debated, we say so.
