protocerebral bridge glomerulus

ID: FBbt_00003669

One of the 18 slices that make up the adult protocerebral bridge, 9 on each side of the midline, numbered 1-9 from medial to lateral. (Ito et al., 2014, Ito and Awasaki, 2008, Wolff et al., 2015, Hanesch et al., 1989, Boyan and Williams, 2011)

The identification of the most medial slice (slice 1) by Wolff et al., 2015 meant that the domain that was previously called slice 1 corresponds in fact to slice 2. Author mentions of 8 slices in the protocerebral bridge indicates that they are using the old nomenclature. Each of the two neighboring slices (2-3, 4-5, 6-7, 8-9) are associated more closely because small-field columnar neurons innervate the fan-shaped body via the protocerebral bridge, and these neurons are generated by the same neuroblasts, forming four groups on each side of the midline, from lateral to medial: segment pair W, X, Y and Z (Boyan and Williams et al., 2011; Ito and Awasaki, 2008.
