Edelstein and her colleagues have compared misophonia to synesthesia in terms of connectivity between different brain regions as well as specific symptoms. [1] They hypothesize that "a pathological distortion of connections between the auditory cortex and limbic structures could cause a form of sound-emotion synesthesia."
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 ...
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.
The cause of synesthesia is unknown. It may be a "wiring" issue in the signals being brought to the brain, it may occur from the brain’s interpretation of the signals it receives, or there may ...
Chromesthesia or sound-to-color synesthesia is a type of synesthesia in which sound involuntarily evokes an experience of color, shape, and movement. [ 1 ] [ 2 ] Individuals with sound-color synesthesia are consciously aware of their synesthetic color associations/ perceptions in daily life. [ 3 ]
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.
How someone with grapheme–color synesthesia might perceive (not "see") certain letters and numbers. Grapheme–color synesthesia or colored grapheme synesthesia is a form of synesthesia in which an individual's perception of numerals and letters is associated with the experience of colors. Like all forms of synesthesia, grapheme–color ...
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 ...
