Soma location: 1, innermost amacrine cell layer; 2, middle amacrine cell layer; 3, outermost amacrine cell layer. *Subtypes described by Connaughton et al. [18]: NF varicose 1 (Aoff-s1n); NF smooth ON/OFF (Adiffuse-1); MF varicose OFF (Aoff-s2); WF varicose OFF (Aoff-s1w); WF varicose ON (Aon-s5); WF varicose ON/OFF bistratified (Aon-s1/s5); unclassified (Aon-s4). GCL, ganglion cell layer; MF, medium-field; NF, narrow-field; S, stratum; SD, standard deviation; WF, wide-field.
