Interesting paper in Nature: The chimpanzee with synaesthesia “The finding hints that chimps, like humans, experience some form of synaesthesia, an uncommon condition in which the senses become intertwined, says Vera Ludwig, a cognitive neuroscientist at Charité Medical University in Berlin, Germany, who led a study published this week in Proceedings of the National Academy of Sciences1.
