static picture of a monkey face you get these sort of transient responses and in fact the only way to drive a sustained response in an IT neuron at the end of the ventral visual pathway is to show a dynamic stimulus so this is very much at odds with how cnn's work because they have no intrinsic notion of time you put in an input you get an output it's a static thing so something is clearly going on here and there's all kinds of interesting rich dynamics here where sometimes it's sustained sometimes it's not sometimes
