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...

The time course of task switching: a speed--accuracy trade-off analysis.

29 Sep 2009 On each trial of this study, participants either switched between or repeated two simple, two-choice tasks involving either letter or digit classifications. Speed-accuracy trade-off (SAT) curves were obtained using the response-signal method of ... 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...

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.
