Synesthesia (also spelled synæsthesia or synaesthesia, plural synesthesiae or synaesthesiae) - of old Greek σύν (syn), importantly „also, “and of αἴσθησις (aisthēsis) and mean „feeling “'- is a neurologically created phenomenon, in which suggestion from a sensory or cognitive course leads to the automatic, involuntary experiences in a second sensory or cognitive course. In a general form synesthesia, color admits synesthesia, letters or numbers is noticed, as as Graphem →, while in the linguistic Ordnungspersonification, colored in the numbers, in the days of the week and in the months of the yearly in itself procurementnesses to mention. In the spatial sequence or number form synesthesia, numbers, months yearly and/or days of the week accurate positions in the area out-get (e.g., 1980 can be far as 1990 „away “) or can have a three-dimensional opinion of a yearly as diagram (right around or left around).

Sometimes during cross-sensory metaphors (e.g., „loud shirt “, „bitter wind “or „stacheliges laughter “) to be described, as „synesthetic “, applicable neurological is involuntary synesthesia. It becomes estimated that synesthesia like 1 in 23 persons over its distance of the variants (Simner et al. to be so predominant can. 2006). Synesthesia runs strongly in families, but the accurate mode of the inheritance has to be determined. Also sometimes Synesthesia is reported of the individuals under the influence of the psychedelischen drugs, after a notice or as consequence of the blindness or the deafness. Synesthesia, which develops from such not genetic cases, characterized as being added synesthesia, in order to differentiate it from the more general kongenitalen forms of synesthesia. The being added thing synesthesia, drugs or notice with includes (however those not blindness or the deafness) refers apparent only sensory ones linkings like more soundly → sight or note → audition also; there are few if culture-based, learned sets of each possible reported drop with including such as Grapheme, Lexeme, days of the week or months of the yearly.

Although synesthesia the topic of the intensive scientific investigation was end of 1800s and the early 1900s, it was left largely in the mid-20th century and was rediscovered only recently by the modern researchers. Psychological research has shown that synesthetic experiences can have measurable behavior consequences, during neuroimaging function studies marked, differences concerning the samples of the brain activation (for a report Hubbard and Ramachandran 2005 sees).

To take prisoner can, many people with synesthesia use their experiences, in order to help during their creative process, and many non synesthetes tried to cause works of art which it is as to experience synesthesia. Psychologists and neurologists do not only study synesthesia for his associated interest, in addition, for the views, which there can be to the cognitive and perception processes, which arise in everyone, synesthete and non synesthete directly.
