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 ...
There are at least 80 types of synesthesia. [23] In August 2017 a research article in the journal Social Neuroscience reviewed studies with fMRI to determine if persons who experience autonomous sensory meridian response are experiencing a form of synesthesia. While a determination has not yet been made, there is anecdotal evidence that this ...
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 ...
In 2006, the journal Cortex published a special issue on synesthesia, composed of 26 articles from individual case reports to functional neuroimaging studies of the neural basis of synesthesia. Synesthesia has been the topic of several recent scientific books and novels and a recent short film has even included characters who experience ...
Studies have looked further into determining whether amputees actually experience mirror touch synesthesia. Four amputees were recruited in a study and asked to observe an assistant's arm being touched at various angles. 61 out of the 64 trials experienced mirror-touch sensations, and when the arm was wiggled, they enhanced the sensations.
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.
A study using magnetoencephalography has shown that color information is available in the brain signal ~200 milliseconds later when accessed via synesthesia in comparison to direct color perception, which is consistent with conceptual mediation. [37] The study supports the idea that synesthesia is a semantic phenomenon – i.e., ideasthesia.
Autism Research is a bimonthly peer-reviewed medical journal covering research on autism and other pervasive developmental disorders. It was established in 2008 and is the official journal of the International Society for Autism Research. It is published bimonthly by Wiley-Blackwell. The editor-in-chief is David G. Amaral (University of ...
