Decoding and reconstructing color from responses in human visual cortex.

2 Nov 2009 How is color represented by spatially distributed patterns of activity in visual cortex? Functional magnetic resonance imaging responses to several stimulus colors were analyzed with multivariate techniques: conventional pattern classification, a ... Read more...

Priming letters by colors: evidence for the bidirectionality of grapheme-color synesthesia.

29 Sep 2009 In synesthesia, stimulation of one sensory modality leads to a percept in another nonstimulated modality, for example, graphemes trigger an additional color percept in grapheme-color synesthesia, which encompasses the variants letter-color and ... Read more...

Seeing sounds and hearing colors: an event-related potential study of auditory-visual synesthesia.

29 Sep 2009 In auditory-visual synesthesia, sounds automatically elicit conscious and reliable visual experiences. It is presently unknown whether this reflects early or late processes in the brain. It is also unknown whether adult audiovisual synesthesia ... Read more...

Technical information about 'Color Perception'

Definition: Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.

Descriptor UI: D003118
