alpha retinal ganglion cell (Mmus) alpha retinal ganglion cell ON-sustained (Mmus) C43 G24 alpha retinal ganglion cell ON-s The G-type nomenclature used here refers specifically to the functional classification of mouse retinal ganglion cells introduced by Baden and colleagues, and is distinct from earlier G-based schemes used for rabbit or other species. Readers should be aware that the same letter–number labels (e.g., "G1", "G2") have been applied in different historical contexts to different animals and criteria (functional vs. morphological), so cross-species or cross-era comparisons of "G" names should not be assumed equivalent without explicit mapping in the primary literature. A retinal ganglion cell type that has a large soma and a wide, monostratified dendritic arbor that stratifies in the inner sublamina of the inner plexiform layer, with dendrites located just proximal to the inner ChAT band (Krieger et al., 2017). It shows a sustained increase in firing rate to ON stimuli (Krieger et al., 2017). It corresponds to the G24 functional type (Baden et al., 2016; Goetz et al., 2022), the C43 transcriptomic cluster (Tran et al., 2019), and is considered the mouse ortholog of the primate ON midget retinal ganglion cell (Hahn et al., 2023). It is molecularly defined by expression of Spp1, Smi32, Brn3b, Calbindin, and Tbr2 (Krieger et al., 2017; Tran et al., 2019).
