Neurophysiology of synesthesia

Recent research examining the neural basis of the two most intensively studied forms of synesthesia suggest that these forms ofsynesthesia are elicited through anomalous activation of color-selective areas, perhaps in concert with hyper-binding mediated by the parietal cortex.

Approaches in Synesthesia Research: Neurocognitive Aspects and Diagnostic Criteria

Synesthesia is a fairly rare phenomenon in which the subject in contact with certain stimulus in one modality experiences unusual extra sensations in other modalities, such as seeing or feeling…

Oneiric Synesthesia: Preliminary Evidence for the Occurrence of Synesthetic-Like Experiences During Sleep-Inertia

Synesthesia is a condition that involves atypical binding between two seemingly independent sensory modalities. The neural origin of this condition is controversial: Although some claim that…

Neuroanatomical bases for synesthesia and their implications for perception and consciousness

It will be demonstrated that both perceptual and concept driven hypotheses are crucial to the understanding of the inner neural mechanisms of synesthesia, and that a wide heterogeneity between synesthetic subjects is suggested.

Synesthesia, Then and Now

Puzzling in its diversity and resistant to simple theoretical accounts, synesthesia has been a subject of scrutiny and investigation for more than a century. Over 30 years ago, the present author…

By first appreciating the similarities between normal sensory perception and synesthesia, one can use what is known about synaesthesia, from behavioral and imaging studies, to inform the understanding of “normal” sensory perception.

Synesthesia and its Cognitive Correlates

Results showed that synesthetes performed significantly worse than controls on the Wisconsin Card Sorting task, a measure of psychological flexibility and perseveration, but not on the Stroop, Simon or Flanker tasks (measures of attention and inhibition) or the digit span task (a measure of memory).

Synesthesia and music perception

It is proposed that the existence of a lower, unconscious degree of synesthesia in non-synesthetes would be functional, aiding the construction of abstract associations between different perceptual fields.

Synesthesia, hallucination, and autism.

This paper explores the possibility that many forms of synesthesia can be understood as experiencing what I will call "second-order secondary properties," that is, experiences of properties of objects induced by the secondary qualities of those objects.

What can synaesthesia tell us about our minds

It is suggested here that synaesthesia might play a compensatory role during the sensorimotor stage of development and be seen as an effect of some deficiency that concerns double integrative processes.

The perceptual reality of synesthetic colors

The subject, in contrast to non-synesthetic subjects, accomplished the task with relative ease because the target of the search had a different synesthetic color from the distractors, indicating that synesthetic experiences appear to originate from a binding of color and form that takes place within central stages of visual processing.

It is suggested that a more complete understanding of this fascinating phenomenon will require a clearly articulated combination of well-designed experimental studies and the subjective reports of synaesthetes.

Functional magnetic resonance imaging of synesthesia: activation of V4/V8 by spoken words

Using functional magnetic resonance imaging (fMRI), this work locates the region activated by speech in synesthetes to area V4/V8 in the left hemisphere, and demonstrates overlap with V3/V4 activation in normal controls in response to color.

It is concluded that synesthesia is a genuine perceptual phenomenon that can have substantial influence on visual processing and is within the focus of attention.
