Are Rotations in Perceived Visual Vertical and Body Axis After Stroke Caused by the Same Mechanism?

Abstract

Because rotations in egocentric and allocentric reference systems found after stroke are differently modulated by lateral tilts, they are not due to a single underlying mechanism. However, they share common bases and can be simultaneously reduced by ipsilesional body tilt. Differences in the way somesthetic information is integrated may explain the differences in LBA and SVV.
