A podcast of Australian Radio National's All in the Mind program.
David Eagleman is a neuroscientist and author, and in the podcast they discuss his writings (which are mind blowingly good) and his work in regard to synesthesia (people who hear colours and taste sounds).
Essentially, the brain is wired in such a way that we can all experience synesthesia, and he specifically mentions LSD and DMT as a means to do so, which I thought this community might find interesting.
Hopefully overseas ISPs can download the podcast, otherwise there are transcripts. I highly recommend this.
