Functional Characterization and Anatomical Identification of Motion Sensitive Neurons in the Lobula plate of the Blowfly

Fig. 1 a —c. Motion sensitive neurons of the lobula plate of Calliphora erythrocephala stained by intracellular injection of procion yellow. The tracings (a, b) were obtained from 12 «m frontal sections and show the injected cells drawn into a semi-schematic vertical elevation of the brain (lateral structures, indicated by thin lines: lobula plate and medulla; oval structure in the center: oesophagus), a. The north horizontal cell (NH) and the dorsal centrifugal horizontal cell (DCH). b. The heterolateral Hl-Cell (dendritic arborisation: right lobula plate; telodendron: left lobula plate), c. Photographic montage of a type A vertical cell of the left lobula splate. The montage is from technical reasons uncomplete. Most of the fine dendritic side brandies in the lobula plate, especially those, emerging from the ventral main dendrite are not shown here. Me = medulla, Cal = calyx, Oes = oesophagus. Calibration markers: 100 am (b), 50 /urn (c).
