PPL2ab

ID: FBbt_00100220

A dopaminergic neuron whose cell body is located in a cluster of approximately 6-7 cell bodies in the cortex of the posterior inferior lateral protocerebrum of the adult brain (Mao and Davis, 2009). Members of this group send processes to various parts of the brain: one group send processes to the calyx, the inferior portion of the lateral horn and broad areas in the middle superior medial protocerebrum; another group sends processes to the calyx, the entire lateral horn and broad areas of the middle superior protocerebrum; another subgroup innervates the lobula and broad protocerebral areas; and a final group innervates the posterior lateral protocerebrum.

Mao and Davis (2009) identify 8 protocerebral clusters coincidentally positive for TH-GAL4 activity and tyrosine hydroxylase immunoreactivity, implying these cells are dopaminergic. The cluster of neurons is so named because it appears to correspond to a double cluster (called PPL2ab) of TH-positive neurons in the blow fly (Nassel and Elekes, 1992), though Mao and Davis (2009) were unable to identify two subclusters. Hartenstein et al. (2017) - FBrf0234128 call PPL2ab "PPL2a" and "PPL2p", and call PPL2c "PPL2b" and "PPL2d".
