Episode 107: Synesthesia / Synesthesia Quiz
On today’s episode, Ali asks Asif about the phenomenon of synesthesia (2:33). Asif gives the definition of the term and gives several examples of synesthesia. He discusses how it is thought to possibly be genetic, and describes how common it is (occurs in 1 in 2000 people!). Asif talks about acquired cases (i.e. from strokes) as well as the theories as to what causes this phenomenon (disinhibited feedback between regions vs the amount or pattern of dendritic and/or axonal connections). Then Asif gives Ali a quiz on famous people who are reported to have synesthesia (17:44).
