Ignoring left and far: an investigation of tactile neglect.

The aims of this paper were to identify patients with tactile neglect, to corroborate its independence from visual neglect, to ascertain its presence along the radial dimension of space and to detect a gradient of performance, as recently reported for visual neglect. To this end eight patients with vascular right cerebral lesions and 28 healthy controls have been tested with a modified version of the tactile maze test of De Renzi et al. [Cortex, vol.

The case is reported of a 9-month-old infant affected by severe recidivating attacks of melena in whom the diagnosis of Meckel's diverticulum was delayed by the repeated negativity of instrumental tests.
