Synesthetes can often “see” music as colors when they hear it, and “taste” textures like “round” or “pointy” when they eat foods. In prior experiments, it has been shown that synesthetes are more accurate and faster to respond when the colour of the letter was congruent to their perceptual experience (e.g., a red A) versus when it is incongruent with their experience (e.g., a blue A) 56). Guru Mag. Ward J. Annu Rev Psychol. It’s possible for it to develop later. However, studies have shown that many synesthetes will see some letters the same way (for example, ‘A‘ is likely to be red). Front Hum Neurosci 2013; 7:603. 70) have shown that projectors exhibited effective connectivity patterns involving a bottom-up mechanism, whereas associators used a top-down mechanism. Mroczko-Wasowicz A, Werning M. Synesthesia, sensory–motor contingency, and semantic emulation: how swimming style–color synesthesia challenges the traditional view of synesthesia. People with synesthesia experience unusual sensations (e.g., of color, of taste) when doing things that wouldn’t usually trigger those sensations for non-synesthetic people. 2009 Feb; 20(2):258-65.
Tomson, S.N. Dehay C, Kennedy H. Cell-cycle control and cortical development.
The use of psychedelic drugs can heighten and connect your sensory experiences. vision). In either case, the experience of synesthesia should induce neural activity in the regions normally involved in the experience of the concurrent (the induced association).
), sensory triggers that consistently and predictably cause interplay between senses (e.g., every time you see the letter A, you see it in red), ability to describe their unusual perceptions to other people, Vladimir Nabokov (acclaimed writer; wrote in his autobiography of his “colored hearing”). MacLeod, C.M. If the synesthesia does prove to be problematic then psychological treatment may be of assistance. In: Simner J, Hubbard EM, editors. Cases have also been reported in which the acquired experience is simpler than the developmental counterpart, often similar to light flashes (phosphenes) or pure color experiences 50). Theor Hist Sci 2013; 10:125–134. »Introduction: Colored-Olfaction This is one of the most common types of synesthesia. For certain people, the stimuli are limited, and only a few types of sounds will trigger a perception. Van Leeuwen TM, den Ouden HEM, Hagoort P. Effective connectivity determines the nature of subjective experience in grapheme–color synesthesia. 2001 Jan 1; 5(1):36-41. https://www.cell.com/trends/cognitive-sciences/fulltext/S1364-6613(00)01571-0.
There is no specific test for this condition. Treatments for Synesthesia (Colored-Olfaction) include: Read more about treatments for Synesthesia, Treatment of Synesthesia: For more treatment information about Synesthesia, see treatment of Colored-Olfaction (Synesthesia). Consequently, the brain chooses to respond to a sensation or combination of sensations that it knows. However it is not certain whether participants are performing better on congruent Stroop tasks because they are experiencing synesthesia, or whether it is merely a strong learned association due to prolonged reading of the books 57). Synesthesia and cortical connectivity – a neurodevelopmental perspective. There are multiple types of synesthesia, all with different symptoms.

Anything that involves damage to the nerves or nervous system can cause dysesthesia. Speaking with a mental health professional may also help you to see the value synesthesia can add to your life. Such neural activation could be due to extra neuronal connections, in particular from neighboring regions (cross-activation theory), or from a difference in neuronal transmission (disinhibited feedback theory). Synesthesia is an extraordinary way of perceiving the world, involving experiences of connections between seemingly unrelated sensations, images or thoughts 1). »Symptoms of Colored-Olfaction Experiment: Try Lumosity’s Online Brain Games. Do the instruments each seem to have a different color? This puts an end to certain myths surrounding the visualizations that come with particular types of the neural condition. The cross-activation theory would not predict drug induced synesthesia to be possible, as these individuals do not have the increase in connection between modalities suggested to be responsible for causing synesthesia. Common pharmaceutical or surgical treatment options include: Some natural treatment options might help relieve chronic pain, including nerve pain such as dysesthesia. Some include: Grapheme-color synesthesia. Proc Natl Acad Sci USA 1991; 88:2083–2087. J. Simner. Psychophysical investigations into the neural basis of synaesthesia. For example, scans of people who say they hear colors show they have a bigger brain response when they hear a sound. 2015;9:103. Sinke C, Halpern JH, Zedler M, Neufeld J, Emrich HM, Passie T. Conscious Cogn. Audioalgesic and audiovisuoalgesic synesthesias: epileptic manifestation. Experientally, acquired synesthesia may be indistinguishable from developmental synesthesia, though it is sometimes less inducer-specific, that is, the same concurrent may have several different inducers 49). Curr Biol 2014; 24:687–692.
This phenomenon could be triggered by either presenting a picture of a swimming individual or asking the tested individual to think about a given swimming style. When a person with number-form synesthesia thinks about numbers, a number map is involuntarily visualized. Cogn Neurosci 2014; 5:128–130.
So far, over 80 types of synesthetic phenomena have been described 17), 18).
There are multiple types of synesthesia depending on what the person with the condition experiences. A standardized test battery for the study of synesthesia. Like developmental synesthesia, acquired synesthesia tends to be automatic and systematic over time, though in some cases it only persists for a limited time period 48).
