part of adult brain fiber system adult superior fiber system 2010-11-30T03:10:01Z FBbt:00100349 May be equivalent to or overlap the longitudinal superior medial fascicle (loSM), which has a similar medial location between the superior protocerebrum and inferior protocerebrum (inferior neuropils) in Lovick et al. (2013) - FBrf0223329 - https://orcid.org/0000-0002-1373-1705. The superior fiber system is a prominent fiber system in the superior adult brain (Ito et al., 2014). It lies superior-lateral to the fan-shaped body and anterior to the superior part of the medial antennal lobe tract (Ito et al., 2014). It demarcates the boundaries between the superior lateral protocerebrum (posterior-medial region), superior intermediate protocerebrum (posterior region), superior medial protocerebrum (posterior-lateral region) and superior clamp (superior-medial region) (Ito et al., 2014). fly_anatomy.ontology SFS superior fibre system VFB:FBbt_00100349
