Similarly, studies have found that while people with autism have fewer neural connections between distant parts of the brain, they have more local or short-range connectivity in some brain areas. Brain-imaging studies have found evidence of particular patterns of brain connectivity in both synesthesia and autism.Īccording to one hypothesis, people with synesthesia have more neural connections between brain regions compared with people who don't have the condition. DOI: 10.But now, looking back at previous studies, evidence does suggest there are underlying similarities between the two conditions, the researchers said. Synaesthesia: The prevalence of atypical cross-modal experiences. Personality and cognitive profiles of a general synesthetic trait. The induction of synaesthesia with chemical agents: A systematic review. Are synesthetes exceptional beyond their synesthetic associations? A systematic comparison of creativity, personality, cognition, and mental imagery in synesthetes and controls. Survival of the synesthesia gene: Why do people hear colors and taste words?

But other stimulants, like cannabis, alcohol, and even caffeine, have also been shown to cause temporary synesthesia. Mescaline, psilocybin, and LSD have been studied for their ability to induce this phenomenon. The use of psychedelic drugs can heighten and connect your sensory experiences. Some substances can cause you to temporarily experience synesthesia. That’s why researchers believe that people who have synesthesia have a high level of interconnectedness between the parts of the brain that are tied to sensory stimulus. So not only will your primary visual cortex be stimulated by the color, your parietal lobe, which tells you what something tastes like, is stimulated, too. If you have synesthesia, you may also feel like you can taste the color of the wall while you look at it. Looking at a bright neon yellow wall, for example, will light up the primary visual cortex, at the rear of your brain. Research indicates that synesthesia can be genetically inherited.Įach one of your five senses stimulate a different area of your brain. People who experience synesthesia are usually born with it or develop it very early in childhood.
