Scientific works of P. Fleksiga are devoted to studying of a structure of a brain of animals and the person, hl. obr. a brain of newborns and children in various stages of post-natal ontogenesis. Investigating process of formation of a myelin cover of nerve fibrils of a head and spinal cord, he established the sequence of myelination in ontogenesis of various sites of c. N of page (see Myelination). On the basis of rates of miyelo-genesis of a cerebral cortex of P. Fleksig distinguished projective, intermediate and associative (or primary, secondary and tertiary) fields; this division also nowadays keeps the value. P. Fleksig for the first time allocated primary visual and acoustical pathways, a temporal and bridge bunch, in details described the course of pyramidal ways, a structure of a corpus collosum. The back spinnomozzhechkovy way described by it entered neurology as the highway Fleksiga (see. Conduction paths).
