Adult Nervous system Synaptic neuropil domain

Synaptic neuropil domain of the adult protocerebrum that receives extensive arborizations from visual projection neurons from the lobula and the medulla, projecting via the anterior optic tract. It protrudes from the anterior-most area of the ventro-lateral neuropils and is slightly detached from the ventro-lateral protocerebrum. This neuropil is absent from the larval brain, being formed during pupal development. (Pereanu et al., 2010, Ito et al., 2014)

Otsuna and Ito (2006) suggest that the optic tubercle may be divided into three regions according to the density of arborizations. The medial-most (optu1) and lateral-most (optu3) contain dense arborizations of the Lcn10 neurons, whilst the area between these regions (optu2) is essentially devoid of the lobula columnar neurons.
