Supplementary figure 4: Synapsin staining of 17 additional olfactory lobes from The olfactory pathway in the peracarid crustacean Parhyale hawaiensis: new insights into the evolution of olfactory processing in Pancrustacea

(a) – (q) Single optical sections (thickness 0.3 µm) of synapsin staining of 17 additional olfactory lobes. Optical sections are form a middle plane of the olfactory lobes. All images are oriented with dorsal towards the top, anterior towards the viewer, and left olfactory lobes mirrored to show the right side. Syn – anti-synapsin staining.
