Figure 5

Immunolocalization of synapsin (SYNORF 1; green) in a whole mount of the ventral nerve centre of adult Sagitta setosa combined with a nuclear marker (red; ventral views; A is black-white inverted). Synaptic contacts are confined to the central neuropil core which shows a highly ordered subdivision into ca. 80 serially arranged microcompartments. Scale bar: 50 μm.
