Do you ever synaesthetically taste something you’ve never eaten before?
It can be difficult to articulate a particular sensation and compare it to a foodstuff. These things are specific and very, very complex. When I’ve taken part in research, I could write maybe half a page of A4 on a particular word’s effects.
Ever since I was young, I had a taste for the word ‘expect’ and I could never quite put my finger on what it was. One day, I bought a packet of Marmite-flavoured crisps. When I had one, it clicked – that’s the taste of “expect”! If I had to describe it I’d say it’s a bit tangy, slightly thick but crunchy.
I get lots of metallic tastes that I can’t describe, other than saying it’s smooth or rough. The name David gives me a very strong taste of cloth, a bit like sucking on a sleeve.
How has it affected your life?
When I was younger, I used to choose friends according to whether they tasted nice or not. When I got older, it used to affect my choice of girlfriend. Their name would be just as attractive to me as the way they looked or their personality.
The results showed significantly greater hippocampal atrophy in individuals reporting a life-changing religious experience. In addition, they found significantly greater hippocampal atrophy among born-again Protestants, Catholics, and those with no religious affiliation, compared with Protestants not identifying as born-again.
The authors offer the hypothesis that the greater hippocampal atrophy in selected religious groups might be related to stress. They argue that some individuals in the religious minority, or those who struggle with their beliefs, experience higher levels of stress. This causes a release of stress hormones that are known to depress the volume of the hippocampus over time. This might also explain the fact that both non-religious as well as some religious individuals have smaller hippocampal volumes.
