In mirror-touch synaesthesia, the person experiences sensations when they see others being touched. James’ condition is known as word-taste or lexical gustatory synaesthesia, which is a relatively rare form of synaesthesia. Several theories exist as to why the condition occurs – some suggest that it happens because of the cross-wiring of certain sections of the brain. Others say that everyone is born with these cross-connections, but it fades away with time for most people. There have been cases of synaesthesia occurring after an injury to the brain. “We now know for a fact the brains of people with synaesthesia are different to other people in two ways,” says Dr. Julia Simner of Edinburgh University. “Brains of synaesthetes have extra clusters of connectivity and there are differences in the grey matter of the brain – an extra thickness is seen in certain areas.”

Interestingly, James’ condition wasn’t diagnosed until he was an adult. “When I was ten, my parents took me to a family doctor as I was getting distracted by flavours when sitting exams—the sound of pencils rolling off desks would taste like wholegrain bread with big lumps in it, and it would put me off my work,” he told Vice. “The doctor told them it was part of growing up, that I had an overactive imagination and would grow out of it. During my teenage years I was told I was just attention-seeking. I didn’t even learn that synaesthesia existed until I was 20.” When he finally received the results of an MRI scan eleven years later, it finally proved to him that the condition was real. “It was clear that I had an extra link running between the part of my brain that deals with sound and the part that deals with taste perception,” he said. “I gained a lot more confidence in speaking openly about being a synaesthete—it led me to become the president of the UK Synaesthesia Association.” Prof. Jamie Ward from the University of Sussex, who has further studied James’ case in detail using various brain scanning techniques, said: “When we’ve asked James to think about words which have good and less palatable tastes to him, we see many parts of the brain lighting up, including areas associated with taste, emotional processing and mental imagery”

James himself seems to have inherited the condition from his mother, who “sees days of the week as colours.” He says that his experience of synaesthesia is as natural as breathing. He can’t remember a time when he didn’t have it, and as a child, it never bothered him. But now, as an adult, he says there are times when the constant bursts of flavors on his tongue can be a bit of a nuisance. Sometimes, if he comes across a person with an overpowering name, he prefers to refer to them using their middle names, or gives them a new one. “Words and sounds go ‘bink, bink, bink’ in my mouth all the time, like a light flickering on and off,” he said. “Some tastes are very quick but others can last for hours and make me crave that particular thing; I’ll feel distracted until I actually eat it.” Regular activities like watching TV or going to the cinema are too difficult for James, because there are too many noises. He also finds it “unbearably annoying” when a word triggers a strong taste that he isn’t able to identify. The word ‘expect’, for instance, troubled him for several years – it gave him a savory flavor that he couldn’t quite place. It wasn’t until he tried a Marmite crisp for the first time that he was able to register the flavor. “I remembered that when I was in infant school, there used to be a tuck shop where you could buy these Marmite-like OXO crisps—and that is what ‘expect’ tastes like to me.”Despite the inconveniences, James is so used to perceiving the world through taste that he can’t imagine any other way of doing things. So when he was offered the chance to temporarily disable his sensory experiences, he declined. “It would be like someone asking you if you wanted to switch off your sight for 20 minutes,” he said. via BBC
