Structure of the pecten neuropil pathway and its innervation by bimodal peg afferents in two scorpion species
Fig 6
Axonal pathways of the pectines in Mesobuthus eupeus.
. Maximum projections of horizontal cLSM stacks. Tubulin-immunoreactivity: grey/black. (A) A major tract runs along the posterior pecten neuropil (PPN) laterally (outlined arrowhead). The anterior pecten neuropil (APN) includes a longitudinal tract (outlined arrowhead). Hemiganglia are connected by commissure (outlined star). (B) Higher magnification of PPN2. The glomeruli (outlined arrowheads) and bilateral lobules (outlined arrows) are demarcated by axonal fibres. (C) Higher magnification of PPN1. Afferent bundles are located at the posterior end and are organised in parallel fashion (outlined arrowhead). Abbreviations: a: anterior; APN: anterior pecten neuropil; p: posterior.
