Abstract

The existence of separate systems for processing geometric and non- geometric spatial information was studied. Twelve neglect patients were asked to reorient themselves in a room using only geometric information or to integrate the information with relevant visual cues both in the presence and in the absence of transcutaneous electrical neural stimulation (TENS). In the absence of TENS, all patients were greatly impaired in coding geometric information, and they had difficulty in coding non-geometric information. TENS significantly improved the ability to code shape-based representation, but is ineffective with non-geometric representations (such as color). The data support previous findings on neglect patients suggesting the presence of separate, independent neural systems subserving different types of space representation.
