Grapheme-color synesthetes experience specific colors associated with specific number or letter characters. To determine the neural locus of this condition, we compared behavioral and fMRI responses in six grapheme-color synesthetes to control subjects. In our behavioral experiments, we found that a subject's synesthetic experience can aid in texture segregation (experiment 1) and reduce the effects of crowding (experiment 2). For synesthetes, graphemes produced larger fMRI responses in color… Expand
The neural bases of grapheme-color synesthesia are not localized in real color-sensitive areas.
TLDR
It is found that color areas and retinotopic areas were not activated by synesthetic colors, whatever the strength of synesthetic associations measured objectively for each subject, and that the key to synesthetic color experience might not lie in the color system. Expand
The neuroanatomy of grapheme–color synesthesia
TLDR
The hypothesis of local anatomical differences in cortical characteristics in the vicinity of the V4 complex supports the hypothesis that the observed altered brain anatomy in grapheme–color synesthetes might be the anatomical basis for this particular form of synesthesia. Expand
Impaired acquisition of novel grapheme-color correspondences in synesthesia
TLDR
To examine the presence of latent color associations for novel characters, synesthetes and controls were trained on pre-defined associations between colors and complex shapes, on the assumption that the prescribed shape-color correspondences would on average differ from implicit synesthetic associations. Expand
Similarly shaped letters evoke similar colors in grapheme–color synesthesia
TLDR
The CCT model of synesthesia, which posits that in synesthetes connections between grapheme regions and color area V4 participate in a competitive activation process, is supported and early perceptual mechanisms as driving factors in the elicitation of synesthetic hues are implicate. Expand
Is the Sky 2? Contextual Priming in Grapheme-Color Synaesthesia
Grapheme-color synaesthesia is a neurological phenomenon in which particular graphemes, such as the numeral 9, automatically induce the simultaneous perception of a particular color, such as theExpand
Does Binding of Synesthetic Color to the Evoking Grapheme Require Attention?
TLDR
It is proposed that the mechanisms giving rise to chromatic-graphemic synesthesia appear to follow at least some principles of normal binding, and even synesthetic binding seems to require attention. Expand
Type-based associations in grapheme-color synaesthesia revealed by response time distribution analyses
TLDR
Response time distribution analyses indicate that color sensations in synaesthetes are not simply the extreme form of normal letter-color associations, and cannot be attributed to demand characteristics. Expand
Effective Connectivity Determines the Nature of Subjective Experience in Grapheme-Color Synesthesia
Synesthesia provides an elegant model to investigate neural mechanisms underlying individual differences in subjective experience in humans. In grapheme–color synesthesia, written letters induceExpand
Can grapheme-color synesthesia be induced by hypnosis?
TLDR
This work addresses the question of whether synesthesia can be rapidly produced using a hypnotic color suggestion to examine the possibility of “hypnotic synesthesia”, and suggests that hypnotically induced colors are not directly comparable to synesthetic ones. Expand
Inside a synesthete's head: A functional connectivity analysis with grapheme-color synesthetes
TLDR
The results of this study support the idea that the parietal lobe plays an important role in synesthetic experience and suggest that the information flow in grapheme-color synesthetes was already modulated at the level of the primary visual cortex which is different than previously thought. Expand

Contrast Affects the Strength of Synesthetic Colors
TLDR
It is proposed that regions of the fusiform gyrus specialized for letter and number grapheme recognition that have been shown to respond in a contrast dependent manner mediate JC's synesthetic colors. Expand
Synaesthesia? A window into perception, thought and language
We investigated grapheme–colour synaesthesia and found that: (1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral maskingExpand
Psychophysical investigations into the neural basis of synaesthesia
TLDR
It is proposed that grapheme colour synaesthesia arises from 'cross–wiring' between the 'colour centre' (area V4 or V8) and the 'number area', both of which lie in the fusiform gyrus. Expand
On the Perceptual Reality of Synesthetic Color
2 Synesthesia – the mental mixture of real and illusory sensory experiences – is incredibly fascinating to read or hear about but frustratingly complex to study. Those of us who are not synesthetesExpand
The perceptual reality of synesthetic colors
TLDR
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.

Functional magnetic resonance imaging of synesthesia: activation of V4/V8 by spoken words
TLDR
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. Expand
Associating Colours with People: A Case of Chromatic-Lexical Synaesthesia
TLDR
Functional imaging was used to elucidate the neural basis of this form of chromatic-lexical synaesthesia and the interaction of synaesthetic colour experience with the non-synaesthetic perception of external colour. Expand
Does Color Synesthesia Pose a Paradox for Early-Selection Theories of Attention?
TLDR
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. Expand
Synaesthetic Photisms Influence Visual Perception
TLDR
A model in which color information influences the perception of digits through reentrant pathways in the visual system is proposed, which suggests that C's colored photisms influence her perception of black digits. Expand
The physiology of coloured hearing. A PET activation study of colour-word synaesthesia.
TLDR
The results suggest that colour-word synaesthesia may result from the activity of brain areas concerned with language and visual feature integration, as conscious visual experience appears to occur without activation of the primary visual cortex. Expand
