it that's for their artificial neural network part comes from and then they're deep and you know we know that perceptual hierarchies for instance in the and the primate are are sort of deep hierarchical systems and deep CN n sort of capture that but really when you get right down to it you know that's been most of the interplay between these two and I think a lot of us here are sort of trying to think well how can we go back to the brain and get more inspiration but then also how can we use the in you know the deep learning to actually help
