Adult uniglomerular antennal lobe projection neuron that develops from the ventral neuroblast (ALv1) and has dendrites that mainly innervate antennal lobe glomerulus VP4, with a branch crossing into the contralateral VP4 (Marin et al., 2020; Bates et al., 2020). It follows the mediolateral antennal lobe tract to the lateral horn, superior clamp and superior lateral protocerebrum (Marin et al., 2020). There is one of these cells per hemisphere and it is GABAergic (Marin et al., 2020; Bates et al., 2020).
