For example, Edgar Allan Poe physiologically incorrectly explained synesthesia via a connection between tympanum and retina. [1] [2] Scientific works are intended to accurately depict synesthetic experiences. However, as research advances, subsequent studies may supersede or correct some of the specific details in older accounts.
Synesthesia is a neurologically based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. There are many occurrences of synesthesia in books, television and film.
Although this form of synesthesia was documented as early as the 1890s, [34] [35] researchers have, until recently, paid little attention to it (see History of synesthesia research). This form of synesthesia was named "OLP" in the contemporary literature by Julia Simner and colleagues [36] although it is now also widely recognized by the term ...
The literature contains conflicting definitional criteria for synesthesia, which could bias selection of research subjects and interpretation of results. Synesthesia has long been described as a 'merging of the senses' or as a kind of 'cross-sensory' experience; however, the condition is not purely sensory/perceptual in all individuals.
Synesthesia is a neurological condition in which two or more bodily senses are coupled. For example, in a form of synesthesia known as grapheme-color synesthesia, letters or numbers may be perceived as inherently colored. Historically, the most commonly described form of synesthesia (or synesthesia-like mappings) has been between sound and ...
In many forms, more well-known words and words used with a higher frequency are more likely to have a strong taste association [2] [7] The phonological roots associated with this form of synesthesia drive the current research on lexical–gustatory synesthesia to determine which parts of the brain are active in synesthetes causing the ...
In Flournoy's 1893 reports on OLP, one synesthete identified as Mme L. reports that "1, 2, 3 are children without fixed personalities; they play together. 4 is a good peaceful woman, absorbed by down-to-earth occupations and who takes pleasure in them. 5 is a young man, ordinary and common in his tastes and appearance, but extravagant and self-centered. 6 is a young man of 16 or 17, very well ...
Alternatively, synesthesia may arise through "disinhibited feedback" or a reduction in the amount of inhibition along feedback pathways (Grossenbacher & Lovelace 2001).It is well established that information not only travels from the primary sensory areas to association areas such as the parietal lobe or the limbic system, but also travels back in the opposite direction, from "higher order ...
