Uniglomerular projection neuron 1 of the antennal lobe
The identified neuron PNI arborises in the T3_60 glomerulus. The soma is located in the ventral rind of the AL. It runs via the median Antennocerebralis tract (m-ACT) to the mushroom body calyces and to the lateral horn.

Uniglomerular Projection neuron 2
The identified projection neuron PN II with its soma in the medial rind of the AL can be allocated to the T2_04 glomerulus. PNII is a m-ACT neuron projecting to the lip region of the calyxes and to the lateral horn. Note the overlap with the Pe_1 neuron in the olateral horn: arrow in 2
