{"fact":"Similar to humans, a crow's brain activates a complex network of regions, including those associated with emotion and memory, when processing human faces.","context":"Here we test the hypothesis that birds use a similar system by providing an imaging analysis of an awake, wild animal’s brain as it performs an adaptive, complex cognitive task. We show that in vivo imaging of crow brain activity during exposure to familiar human faces previously associated with either capture (threatening) or caretaking (caring) activated several brain regions that allow birds to discriminate, associate, and remember visual stimuli...","source":"John M.
