Synesthesia is a neurological phenomenon in which stimulation of one sense, leads to involuntary experience in another. It can manifest itself in different ways, as for various senses corresponds to the other parts of the brain. Synesthesia can occur as a tasting of colors or smell sounds.
It appears between the two modes of the senses or perception and taking into account the five basic senses of sight, smell, sound, taste, and touch, and there are at least twenty types of synesthesia. Most often, this disorder occurs between two senses at the same time. However, there were extreme cases in which participated more than two intersecting senses.
A person who experiences synesthesia can look at the individual letters or numbers see the particular colors such as the letter A in red. Another type is the ability to visualize the colorful shapes and sounds. Frequently perceived colors, take certain shapes like squares or circles. These involuntary visualizations are the result of the interbreeding reaction in the parietal lobe – part of the brain that is involved in numerical and spatial cognition.
Personification is another unusual type of synesthesia, in which certain experiences are associated with an ordered sequence of different personalities – for example, a person sees the letter A, which shows the text as a bad thing.
Rarer synesthesia is feeling different flavors while listening to certain words or phrases. Relations between the words and the sense of taste, however, are limited to those with whom the person has been exposed to in childhood. If, therefore, does not come into contact with the taste of chocolate or bacon as a small child, will not feel them later hearing the words or phrases associated with them.
The symptoms synesthesia
The symptoms synaesthesia is much more than tasting of colors or smells perception of sounds. The disorder occurs in most women (six times more often than men). Neither is it a disease.
People affected by synesthesia usually have above-average intelligence. The disorder can appear as early as infancy before the child reaches four months. The reactions are then automatically, and the child, accustomed from childhood, to stimulate the sensory treat them naturally – not as something irregular or coming off from the norm.
- irregular sensory impressions – the child does not feel it as an anomaly, but parents may notice some reactions to the child’s tastes and smells, which for them are weird,
- consistent trigger reactions – reactions to different stimuli are similar – the same element triggering will be affected to the same senses,
- automaticity of action – for example, if the child is glancing at the text, immediately sees colors distinguish the individual letters in the text – synesthesia is not possible to simulate.
The causes of synesthesia
Synesthesia is not completely discovered, but some experts believe that the cause is purely neurological. Is a disorder extremely rare, and very intriguing, and the researchers also found that it could be inherited or acquired.
Speculation about the causes of synesthesia continues, so maybe soon, science will be able to determine from where the disorder comes. People experiencing synesthesia, consider them as pleasant and neutral. Its diversity and numerous varieties make that not everyone is aware of its occurrence. Many people often do not admit to their differences for fear of ridicule.
People with synesthesia may share some symptoms like a confusion of directions, have a remarkable memory or experience unusually intense migraines. Very often they are also ambitious and strive for excellence. Sometimes, they are much more delicate than the average person, and for that, they are introverts, but incredibly creative and talented in the visual arts, and more.
The treatment of synesthesia
Because high diversity characterizes the disorder, the treatment is not easy to achieve. Are applied, a variety of tests that may help in the treatment of individual states, but so far, the best results are obtained of hypnosis. Many people resign from treatment because the disorder does not bother them.
