ABSTRACT

In the last 5 years before the second world war, a major effort in cytoarchitectonic research was directed toward a more extensive division of the major fields into subfields, especially for the visual cortex. Pathological study of the human brain lead to the assignment of a specialized function to each subfield, with a physiological or psychological designation. For occipital cortical fields, I recall the example of Kleist’s frequently cited brain chart, especially the designations inserted for subfields of area 18 and 19. On the other hand, I recall the reservations of a researcher of a different orientation, that were advanced against the basic concepts in this brain chart.
