A primary neurite projects to and innervates the antennal lobe. Another process projects dorsally to innervate the lateral and medial region of the posterior brain, including the region around the mushroom body. A single neurite crosses the midline and arborizes extensively in the contralateral posterior dorsolateral and anterior basolateral regions. larval serotonergic IP1-2 neuron
