What happens in the brain when you have synesthesia?

Synesthesia is a neurological condition that causes the brain to process data in the form of several senses at once. For example, a person with synesthesia may hear sounds while also seeing them as colorful swirls.

Do people with synesthesia actually see colors?

Only a few synesthetes see colors outside their body. It stays the same over time. If you see the letter “A” in green today, you’ll see it in green 10 years from now. One study asked people with synesthesia to look at 100 words and say the color they saw for each.

How does color synesthesia work?

In grapheme-color synesthetes, seeing a number simply stimulates your grapheme region and the area of your visual cortex that responds to color stimuli [source: Brang and Ramachandran].

What part of the brain does synesthesia affect?

Several brain regions have been shown to be pivotal for synaesthetic experience among them are sensory and motor regions as well as so-called “higher level” regions in the parietal and frontal lobe.

Is synesthesia a mental illness?

No, synesthesia is not a disease. In fact, several researchers have shown that synesthetes can perform better on certain tests of memory and intelligence. Synesthetes as a group are not mentally ill. They test negative on scales that check for schizophrenia, psychosis, delusions, and other disorders.

How do you know you have synesthesia?

If you have synesthesia, you might notice that your senses tend to intertwine, giving your perceptions of the world an additional dimension. Perhaps every time you bite into a food, you also feel its geometric shape: round, sharp, or square.

Do you need a diagnosis for synesthesia?

There’s no clinical diagnosis for synesthesia, but it’s possible to take tests such as “The Synesthesia Battery” that gauge the extent to which one makes associations between senses.

What is the dumbest color?

Pantone 448 C, also dubbed “the ugliest colour in the world”, is a colour in the Pantone colour system. Described as a “drab dark brown”, it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was the least attractive colour.

What is emotional synesthesia?

According to some synesthetes’ reports, their experience involves an emotional sensation in which a conflict between the photism and presented color of a stimulus may evoke a feeling of discomfort.

How do you know if you have synesthesia-Synesthesia Art?

There are many different types of Synesthesia, not just the sound-to-color synesthesia (chromethesia) that I experience. Some people can read or hear a word and they automatically and consistently taste a particular flavor. They may read the word Red and taste yogurt or hear someone say “together” and taste paprika.

What happens in the brain when a synesthete hears a letter?

Some studies have shown that when a synesthete hears a letter or number, that the color area in the brain (the visual cortex) is activated too. For non-synesthete this region was not activated, even if there had been a synesthetic training beforehand.

What kind of research is done on synesthetic brains?

EEG, PET, fMRI and diffusion tensor imaging are among the most prominent techniques to research the structural and functional differences of synesthetic brains and those of non-synesthetes. Most of the studies that were done were focusing on sound -> color synesthesia and grapheme -> color synesthesia.

How many people in the world have synesthesia?

Some people see numbers in different colors, feel noises, taste letters and smell pictures. This natural connection of different sensations is called synesthesia. One in 25 people have it worldwide, including Lady Gaga. Musician Kaitlyn Hova sees the music she plays in colors.

How can you tell if someone is a synesthete?

In other words, the color of letter “A” does not change for a synesthete over time. This principle of consistency is the foundation of the synesthesia tests. Ask somebody the colors of letters, numbers, weekdays and months. And then repeat this after a while.

Why are grapheme to color synesthesia so common?

Synesthesia may be caused by unusual cases of cross-talk between normally separated brain regions. This might explain why grapheme to color synesthesia is relatively common among synesthetes. Graphemes are thought to be represented at the junction between the parietal and temporal lobes. Information about color is located relatively nearby.

Which is part of the brain produces the color experience?

Additionally, other regions are co-activated, such as the visual cortex that produces the color experience. This co-activation leads to the blending of the senses! You can see here the EEG of a person with synesthesia (it’s my brain) and without. For more about Synesthesia on the brain, read our article here. Hearing a letter.

What happens when you make a synesthetic connection?

Sometimes when people develop these synesthetic connections, for instance between sound and color, they can sometimes develop connections in other areas that have nothing to do with sound and color. The brain almost automatically starts associating other things with colors as well because it’s used to making those associations.
