asymmetrical body
ID: FBbt_00110172
Round synaptic neuropil of the central complex, adjacent to the ventralmost layer (1) of the fan-shaped body and dorsal to the noduli, on either side of the midline (Wolff and Rubin, 2018. The right asymmetrical body is, on average, 4x larger (by volume) than the left and some neurons have a bias towards the right hemisphere in their innervation patterns (Pascual et al., 2004; Jenett et al., 2012; Wolff and Rubin, 2018. In a small proportion (7.6%) of wild-type flies, this structure is symmetrical, with prominent (right side-like) innervation in both hemispheres (Pascual et al., 2004. (Jenett et al., 2012, Pascual et al., 2004, Wolff and Rubin, 2018)
This structure was identified by the expression of the neural protein fasciclin II (FasII) (Pascual et al., 2004. Wolff and Rubin, 2018 claim this is a distinct neuropil to the fan-shaped body based on the restriction of neuronal arbors to one or the other.
