The exploration of space and objects in neglect
This chapter deals with the exploration of space and objects in spatial neglect. The studies demonstrate that both segmentation and rotation of stimuli have an impact on neglect symptoms which can be described in object-centered coordinates. In addition, it outlines experimental data reported on the spatial distribution of neglect patients' spontaneous exploratory behavior and then contrasts these results with the predictions of the enhancement and the normalization models. Moreover, an alternative concept, referred to as integrated space-object map (ISO-map), that prevents the presented problems by combining the enhancement model with a normalization model, is proposed. It is noted that the simulations indicate that both types of coordinates are simultaneously disturbed, suggesting that both coordinate systems might be closely connected in the brain. Finally, it answers how and where the ISO-map might be enforced in the brain.
