wedge
ID: FBbt_00045027
Adult Nervous system Synaptic neuropil domain
An aglomerular, bilaterally paired synaptic neuropil domain that is the inferior-most domain of the ventrolateral neuropils, lying between the anterior and posterior ventrolateral protocerebrum (AVLP and PVLP) and posteriorlateral protocerebrum (PLP), and the saddle and gnathal ganglion. The wedge is lateral to the inferior fiber system and vest. It receives synaptic input from the saddle and the antennal mechanosensory and motor center (AMMC) within it. This includes direct sensory input from antennal mechanosensory neurons that also innervate the AMMC. (Ito et al., 2014)
The anterior wedge corresponds to the inferior part of the vlpr of Otsuna and Ito, 2006; the posterior wedge corresponds to part of the plpr (Ito et al., 2014.
