title: Morphology of bipolar cells and their participation in spatial organization of the inner plexiform layer of jack mackerel retina.
abstract: Morphology of bipolar cells in the jack mackerel retina [Trachurus mediterraneus ponticus (Aleev)] was investigated by the Golgi method. Eight types of bipolar cells are described. It is the first time that cells with an unbranched main dendrite are found in fish retina. It is shown that the inner plexiform layer of the jack mackerel retina contains regular lattices, located at 5 levels and conserted in a characteristic way with the cone mosaic. These lattices are formed by swellings of bipolar cell axons. It is shown that only bipolar cells with small dendritic aborizations (less than or equal to 14 micron dia) take part in this organization.
