| Morphological description: | The LT11 pathway consists of a single neuron. The cell body is located in the anterior dorsal area of the lateral cell body region (Fig. 1). The neuron has tree-like branches in the lobula and form varicosities in two separate layers. The outer (lateral) layer corresponds to the LO3 and 4, and the inner (medial) layer corresponds to LO5 (Fig. 1). In the vlpr the neuron arborizes in roughly the same anterior dorsal area as that of the LT1.
The presynaptic sites are found in the LO3 and 4 layers of the lobula as well as in the vlpr (Fig. 3). The varicosities in the LO5 layer are devoid of n-syb::GFP and are hence likely to be postsynaptic. The LT11 neuron therefore seems to collect information in the LO5 layer and transmit the signal centrifugally to the LO3, 4 layers and centripetally to the vlpr.
