The fiber tracts affected by the patient's lesion.

<p>The patient's acute lesion (a, yellow) and affected fibre tracts (purple) in the chronic brain, superimposed on the patient's fractional anisotropy image. The tracts include at the posterolateral edge of the pulvinar the inferior fronto-occipital fasciculus (b), which projects to the external capsule and the insula.</p

Spatial Hyperschematia without Spatial Neglect after Insulo-Thalamic Disconnection.

Different spatial representations are not stored as a single multipurpose map in the brain. Right brain-damaged patients can show a distortion, a compression of peripersonal and extrapersonal space. Here we report the case of a patient with a right insulo-thalamic disconnection without spatial neglect. The patient, compared with 10 healthy control subjects, showed a constant and reliable increase of her peripersonal and extrapersonal egocentric space representations - that we named spatial hyperschematia - yet left her allocentric space representations intact. This striking dissociation shows that our interactions with the surrounding world are represented and processed modularly in the human brain, depending on their frame of reference
