part of medial lobe of adult mushroom body synaptic neuropil subdomain mushroom body neuropil subdivision adult mushroom body beta'' lobe 2010-09-09T04:31:35Z fly_anatomy.ontology FBbt:00100251 A narrow division lying between the gamma and beta' lobes of the adult brain. Axons innervating the beta'' lobe have axons innervating the alpha' lobe front surface. Via Golgi impregnation and immunostaining, Strausfeld et al. (2003) identifies this highly taurine-immunopositive, aspartate-immunonegative band. However, Tanaka et al. (2008), using an enhancer trap screen, suggest that the neurons composing the alpha''/beta'' lobe should be regarded as a subpopulation of the alpha'/beta' anterior neurons.
