On March 20th, Ed was part of a two-day workshop at the Royal Netherlands Academy of Sciences titled Decoding the Neurobiology of Synaesthesia. The symposium brought together an elite group of scientists who are focused on synesthesia from genetic, psychological and neural perspectives to better understand the mechanisms that give rise to synesthesia, and how the study of synesthesia might help shed light on other, broader issues related to cognitive and neural development.
