obsolete small DN3 neuron [FBbt_00052276]

DN3 neuron that has a relatively small cell body (Reinhard et al., 2022). The majority (around 35 per hemisphere) of the DN3s belong to this class and they are heterogeneous (Reinhard et al., 2022). All of these cells project medially and arborize in the superior medial protocerebrum (Reinhard et al., 2022). Some fibers additionally cross the midline via the middle dorsal commissure and some cells extend into the posterior lateral protocerebrum (Reinhard et al., 2022).

DN3 neuron that has a relatively small cell body (Reinhard et al., 2022). The majority (around 35 per hemisphere) of the DN3s belong to this class and they are heterogeneous (Reinhard et al., 2022). All of these cells project medially and arborize in the superior medial protocerebrum (Reinhard et al., 2022). Some fibers additionally cross the midline via the middle dorsal commissure and some cells extend into the posterior lateral protocerebrum (Reinhard et al., 2022).

Based on comprehensive analysis by Reinhard et al. (2024) - FBrf0261099 the three main groups are large central-projecting, small central-projecting and anterior-projecting. Anterior-projecting cells "also have larger somata than the s-CPDN3", so the 'small central-projecting DN3 neuron' is the only type of 'small DN3 neuron'.
