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...

Visual recalibration of auditory spatial perception: two separate neural circuits for perceptual learning.

2 Sep 2009 A remarkable example of rapid perceptual learning is the visual recalibration of auditory spatial perception, which can result in either a bias (ventriloquism after-effect) or an improvement (multisensory enhancement) in auditory localization. Here, ... Read more...

Acquired cognitive dysfunction with focal sleep spiking activity.

30 Jul 2009 The syndrome of continuous spike-waves during slow sleep (CSWS) is considered an epileptic encephalopathy in which the epileptiform abnormalities may contribute to progressive cognitive dysfunction. The characteristic electroencephalographic feature ... Read more...

Technical information about 'Perceptual Disorders'

Definition: Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.
