From there, neurites extend contralaterally to sparsely innervate the dorsomedial and basomedial regions (Huser et at., 2012). It receives input predominantly in the ipsilateral protocerebrum and has outputs in the contralateral optic neuropil (Larderet et al., 2017). fly_anatomy.ontology serotonergic SP2 neuron 1
