 Abstract: The organization, characterization and connectivity patterns of four different interneurone types were studied with the use of Golgi light- and electron-microscopic techniques. All four cell types originate in the outer chiasma; they have an efferent end-branch in the lamina and an afferent one terminating in the distal region of the second optic ganglion, the medulla. These interneurones are referred to as: (i) Garland-cell: The efferent fibre has on its tangential branch numerous centripetal side branches, so-called “garlands”, which synapse with first- and second-order visual cells. (ii) Y-cell: The lamina branch bifurcates before entering the lamina. It innervates two neighbouring cartridges. Synaptic contacts were seen in two different laminar strata where bottle-brush-like collaterals occurred. (iii) Single bottle-brush cell: The efferent part has only one centrifugal branch, which can be compared morphologically and in terms of synaptology with those of the Y-cell. (iv) Triptychcell: The lamina component innervates three neighbouring cartridges at three different laminar layers interconnecting different first- and second-order visual neurones. The present study provides some essential qualitative and quantitative fine-structural information, which — when compared with adequate physiological data — may lead to a better understanding of the function of the first visual information-processing centre of the bee.
