adult dopaminergic PAM neuron obsolete mushroom body anterior inferior medial cell 2010-09-09T01:41:04Z https://github.com/FlyBase/drosophila-anatomy-developmental-ontology/issues/968 true Obsoleted as it is not clear which cell types are included/partially included in this class. Cells are mostly (or perhaps exclusively) PAM neurons, based on Aso et al. (2014). Tanaka et al. (2008) refer to the MB-AIM as 'MB-APM' on one occasion, perhaps by mistake. fly_anatomy.ontology MB-APM MB-AIM FBbt:00100223 A neuron, whose cell body is located in front of the anterior inferior medial protocerebrum of the adult brain, anterior to the vertical and medial mushroom body lobes (Tanaka et al., 2008). This is a large group of around 50 neurons per hemisphere (Tanaka et al., 2008), which are likely heterogeneous (Aso et al., 2014). The cell body fibers enter the medial lobe through the gap between the gamma and beta' lobes (Tanaka et al., 2008). Within the gamma lobe, neurite projections are limited to the middle segment between the tip and the base of the lobe, named as gamma4 (Tanaka et al., 2008). In the beta' lobe, neurites arborize in the lateral part of the beta'a stratum (beta'a1) and the medial segment of beta'm and beta'p strata (beta'm2 and beta'p2) (Tanaka et al., 2008). At the medial edge of the beta'm and beta'p strata, some of the fibers project to the contralateral lobe (Tanaka et al., 2008).
