Kevin Hoover asked:
How do psychedelic drugs generate synesthetic experiences such as seeing the colours of music?
Duncan - Well, we donít know exactly how that occurs, but we do know that it does occur. It also can occur through brain accident or injury as well. I think itís an unknown question. I mean, what we donít know is if itís the same mechanism or whether itís a completely different mechanism. What we do know is it can occur through taking LSD or Ďacidí that people do indeed experience something very similar to synaesthesia.
Chris - So there you go, if you want to know what itís like, you have to take some LSD, but donít do that, not a good idea.
