General Information
Term lobula tangential neuron LT32 ID (Ontology) FBbt:00100490 (Fly Anatomy)
Definition A lobula tangential neuron whose cell body is located lateral to the esophageal foramen. The cell body fiber runs posteriorly along the esophagus and turns upwards near the posterior end of the brain where it forms a Y-shaped branch. One branch runs laterally to project to the lobula, and the other crosses the midline to innervate the contralateral lobula. Along the trajectory towards the lobula, the fiber forms another collateral branch which innervates the posterior lateral protocerebrum. The main branch reaches the lobula and forms extensive tree-like arborizations with varicosities in lobula layers 5 and 6. There is only one neuron of this type per brain hemisphere.[ FlyBase:FBrf0193607 ]
