(From Mesulam, 1985)
When the neglect is severe, the patient may behave almost as if one half of the universe had abruptly ceased to exist in any meaningful form... Patients with unialteral neglect behave not only as if nothing were actually happening inthe left hemispace, but also as if nothing of any importance could be expected to occur there.
M. Mesulam, 1985
