has characteristic in taxon retinal ganglion cell alpha retinal ganglion cell (Mmus) alpha cell CL:0004117 cell A large-bodied retinal projection neuron with wide monostratified dendritic arbors in defined IPL strata, high neurofilament and osteopontin expression, and a thick, fast-conducting axon. It shows short-latency, non-direction-selective responses with large receptive fields and a distinctive rapid action potential waveform. In mammals it forms about five percent of RGCs and includes four conserved ON and OFF sustained and transient subtypes. retinal ganglion cell A https://orcid.org/0000-0002-5260-9315 BAMS:1009 https://orcid.org/0000-0001-7258-9596 This group includes all of the large bodied/large field RGCs in the rat. Group RGA cells have large somata (15 to 39 micrometers in diameter) and large, radially branching dendritic fields (235 to 748 micrometers in diameter), and many exhibit tracer coupling.
