obsolete distal medullary amacrine neuron Dm8a [FBbt_00110068]

Distal medullary wide-field amacrine neuron whose cell body is located in the cell body rind of the medulla. It branches extensively in medulla layer M6A and extends small centrifugal processes to medulla layer M4. The highest arbor density is found in the center of the cell, within one column, with these regions tiling, while the whole arbor overlaps considerably. In medulla layer M6A, it extends over 10-15 columns in both the anterior-posterior and dorsal-ventral axes. In layer M6A, it is postsynaptic to photoreceptor cells R7 (Gao et al., 2008; Takemura et al., 2013) and presynaptic to Tm5c (Gao et al., 2008; Karuppudurai et al., 2014). It also makes synaptic contacts with Tm9 (in M4) (Gao et al., 2008). The contacts with Tm5c are clustered in the center of the dendritic field of Dm8a, which corresponds to approximately one column. It is a glutamatergic neuron (Gao et al., 2008; Karuppudurai et al., 2014).

Obsoleted due to equivalence with Dm8. Only referred to as Dm8a in Hasegawa et al. (2011) FBrf0213020.
