Direction-specific disruption of subcortical visual behavior and receptive fields in mice lacking the beta2 subunit of nicotinic acetylcholine receptor.

12 Oct 2009 Retinotopic mapping is a basic feature of visual system organization, but its role in processing visual information is unknown. Mutant mice lacking the beta2 subunit of nicotinic acetylcholine receptor have imprecise maps in both visual cortex (V1) ... Read more...

The psychotomimetic effects of short-term sensory deprivation.

29 Sep 2009 People experiencing sensory deprivation often report perceptual disturbances such as hallucinations, especially over extended periods of time. However, there is little evidence concerning short-term sensory deprivation and whether its effects differ ... 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 '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.
