prothoracic gland innervating neuron PG-LP [FBbt_00007457]
Larval neurosecretory neuron that secretes prothoracicotropic hormone (FBgn0013323; McBrayer et al., 2007) and innervates the prothoracic gland. The somata of these neurons (2 per hemisphere) lie in the cortex of the lateral protocerebrum. Their axons, which form extensive collaterals in the brain, run along the anterior brain at the cortex/neuropil interface before traversing the midline and entering the contralateral nervus corporis cardiaci I (NccI) through which they travel to the ring gland. Within the ring gland these axons bypass the corpora cardiaca to innervate the prothoracic gland where they arborize extensively. McBrayer et al., (2007) used enhancer trap expression to confirm that their PG neurons are identical to the PG-LP neurons identified by Siegmund and Korge (2001).
