title: [Cultivation of whole brain slices: a description of the method and the results of its use for culturing the rhombencephalon and midbrain of chick embryos].
abstract: A method and device for obtaining embryo brain slices are described. Results of cultivation of slices of rhombencephalon and mesencephalon are presented obtained in accord with a proposed technique of the "swimming float" (Olenev, 1979). With this cultivation, original topographical relations between brain nuclei and fibrillar tracts remain unchanged that enables us to compare these cultures with histological sections of brain to identify strictly the structures being cultivated. Cultured neurons of nuclei of XII and VIII pairs of cranial nerves have been first described in addition to various divisions of the reticular formation commissura cochlearis dorsalis. Compared to cells examined in the in vivo conditions, neurons of the nucleus cochlearis laminaris, grown in tissue culture conditions, do not make plate-forming structures; dendrites of the neurons of III layer of tectum opticum do not develop. This may be explained by the absence in vitro of any stimulating influence from the acustic ganglion fibres and ganglion cells of the retina on these morphogenetic processes.
