Fig. 13. Balint (1909) reported on a man with a “spatial disorder of attention” (simultanagnosia), “psychic paralysis of gaze” (ocular apraxia), and optic ataxia (see text). The onset occurred in 1894, the patient died in 1906, and an autopsy was performed. Balint pictured the lesions in his patient on lateral views of the hemispheres. He emphasized the role of bilateral lesions of the angular gyri and the sparing of the primary visual cortex (Brodmann's area 17). However, the patient also had damage to the posterior white matter, in which optic radiations travel on both sides, and to the pulvinar, a critical subcortical structure for visuospatial integration.
