Adrian talks about face recognition in homo sapiens:
It turns out that facial recognition and plain old pattern/object recognition are governed by different systems in the brain; we know this because there is something called a double dissocation between them. In other words, there are people who, for some reason, cannot recognise faces but can recognise objects fine, and vice versa. This strongly suggests that they run on different systems.
So how about we leverage our skills at facial recognition by converting other forms of information (say, spike trains, weather patterns, stockmarket data) into facial features? How might that work, eh? It could allow us to sense subtle differences in information and aid our recognition by no end. [more]
