During the past few years we have had the opportunity of studying the vision of patients after resection of a known cerebral area. The present report is an attempt to correlate the results thus obtained with the anatomic knowledge of the course and termination of the geniculocalcarine pathway. In our study the question of macular representation in the optic radiation and cortex early assumed a position of primary interest.

The gross localization of visual function in the occipital lobe has been adequately confirmed by clinicopathologic evidence (Henschen1), studies of myelinization (Flechsig2) and experimental extirpation (Minkowski,3 Munk4). Poljak5 has recently demonstrated a point-to-point relationship between the external geniculate body and the calcarine cortex. Evidence from many sources indicates a localization of the upper retinal quadrant in the upper calcarine lip and the lower quadrant in the lower lip. Henschen6 and Holmes7 further localized the
