The assessment of auditory function in CSWS: lessons from long-term outcome.

30 Jul 2009 In Landau-Kleffner syndrome (LKS), the prominent and often first symptom is auditory verbal agnosia, which may affect nonverbal sounds. It was early suggested that the subsequent decline of speech expression might result from defective auditory ... Read more...

Direct tactile stimulation of dorsal occipito-temporal cortex in a visual agnosic.

26 May 2009 The human occipito-temporal cortex is preferentially activated by images of objects as opposed to scrambled images. Touching objects (versus textures) also activates this region. We used neuropsychological fMRI to probe whether dorsal regions of the ... Read more...

Analysis of lesions in patients with unilateral tactile agnosia using cytoarchitectonic probabilistic maps.

29 Apr 2009 We propose a novel methodical approach to lesion analyses involving high-resolution MR images in combination with probabilistic cytoarchitectonic maps. 3D-MR images of the whole brain and the manually segmented lesion mask are spatially normalized ... Read more...

Technical information about 'Agnosia'

Definition: Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.
