Subcortical Visual Hallucinations

Cortex, 1971
Summary The case material that has been reviewed suggests that lesions at all levels of the neurovisual system may be associated with visual hallucinations. Occurrence of the phenomenon of subcortical visual hallucinations is compatible with what is known about the complex integration of cortical and subcortical visual processes.
