The olfactory neurons that innervate aesthetascs follow the "aesthetasc pathway"; they terminate on the glomeruli composing the paired olfactory lobes of the brain (OL).
Removal of the aesthetasc-bearing portion of the lateral antennule flagellum causes the crayfish to lose as much of its olfactory lobe as if the entire appendage were removed, suggesting that aesthetascs are the primary olfactory sensilla (Mellon, 2000; Horner et al.
In all decapods, ORN axons run within the antennular nerve and terminate within a glomerulus of the ipsilateral olfactory lobe (Sandeman and Denberg, 1976; Sandeman and Luff, 1973; Mellon et al.
The labeled nuclei in the LC always occurred as a tightly packed, string- or ball-like group that was located in the ventral part of the cluster directly adjacent to the neuropil of the olfactory lobe (OL).
In the olfactory pathway, ORNs with dendrites located within the aesthetascs on the distal half of the lateral filament of the antennules project to the olfactory lobe (Schmidt and Ache, 1992).
