Lamina-medulla connections in sol Mutants

Camera lucida drawings of columnar neurons connecting lamina and medulla in the small optic lobes mutant allele KS58. In comparison with the wild type situation (Fischbach and Dittrich, 1989) it is clear that most of the neurons known are present in sol . While their neuronal shapes are pretty normal at the level of the lamina, their arborizations at the level of the medulla tend to be less stratified (one of the reasons why L3 might be difficult to find). Long retinal fibers (Rl) and L1-terminals extend into the proximal medulla.
L1-L5 = lamina monopolar neurons 1 - 5 with their cell bodies in the lamina cortex
T1 = T1 neuron with its cell body in the medulla cortex and arborizations in medulla and lamina (forming so-called baskets in the lamina).
C2,3 = Centrifugal cells 2 and 3 with their cell bodies distal to the lobula plate cortex, dendritic arborizations in the medulla and club-like terminals in the lamina.
Rs = terminal of short retinula cell (of the R1-6 type).
