abstract = {Studying cognitive processes underlying synesthesia, a
condition in which stimulation of one sensory modality
automatically leads to abnormal additional sensory
perception, allows insights into the neural mechanisms of
normal and abnormal cross-modal sensory processing.
Consistent with the notion that synesthesia results from
hyperconnectivity, functional connectivity analysis
(adopting independent component analysis and seed-based
correlation analysis) of resting-state functional magnetic
resonance imaging data of 12 grapheme-color synesthetes and
12 nonsynesthetic control subjects revealed, in addition to
increased intranetwork connectivity, both a global and a
specific (medial and lateral visual networks to a right
frontoparietal network) increase of intrinsic internetwork
connectivity in grapheme-color synesthesia. Moreover, this
increased intrinsic network connectivity reflected the
strength of synesthetic experiences. These findings
constitute the first direct evidence of increased functional
network connectivity in synesthesia. In addition to this
significant contribution to the understanding of the neural
mechanisms of synesthesia, our results have important
general implications. In combination with data derived from
clinical populations, our data strongly suggest that altered
differences in intrinsic network connectivity are directly
related to the phenomenology of human experiences.},
