The analysis of spatial representation biases in patients with hemispheric stroke is the subject of two articles in this issue of the Journal of Neurology, Neurosurgery and Psychiatry. This confirms the growing interest for this topic, because it provides data about the brain coding of spatial information and contributes to explaining the behaviour of patients in clinical situations.
In the elaboration of the representation of the egocentred space, it has been suggested that the reference frame constituted by the medial body axis has a strategic influence on the perceptive motor actions in the peripersonal space.1 The first bias of the representation of this reference was reported in patients with right hemispheric lesions and spatial neglect, and was found in the left–right dimension (lateral) in relation to the head and body positions.
