Mirror-touch synesthesia is a rare condition which causes individuals to experience a similar sensation in the same part or opposite part of the body (such as touch) that another person feels. For example, if someone with this condition were to observe someone touching their cheek, they would feel the same sensation on their own cheek.
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 ...
Women have a higher chance of developing synesthesia, as demonstrated in population studies conducted in the city of Cambridge, England where females were 6 times more likely to have it. [53] As technological equipment continues to advance, the search for clearer answers regarding the genetics behind synesthesia will become more promising.
The genetic mechanism of synesthesia has long been debated, with researchers previously claiming it was a single X-linked trait due to seemingly higher prevalence in women and no evidence of male-male transmission [1] This is where the only synesthetic parent is male and the male child has synesthesia, [2] [3] meaning that the trait cannot be solely linked to the X chromosome.
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 ...
A common example of synesthesia is the association between graphemes and colors, usually referred to as grapheme–color synesthesia. Here, letters of the alphabet are associated with vivid experiences of color. Studies have indicated that the perceived color is context-dependent and is determined by the extracted meaning of a stimulus.
In a study investigating variability within categories of synesthesia, 40% of subjects with chromesthesia for spoken words reported that voice pitch, accent, and prosody influenced the synesthetic color, whereas few subjects reported that volume or speed of talking had any influence. [8]
Examples include synesthesia, sensory substitution and the McGurk effect, in which vision and hearing interact in speech perception. Crossmodal perception, crossmodal integration and cross modal plasticity of the human brain are increasingly studied in neuroscience to gain a better understanding of the large-scale and long-term properties of ...
