| description | A mouse retinal ganglion cell type defined by a large soma and a wide, monostratified dendritic arbor that stratifies just distal to the outer ChAT band of the inner plexiform layer (Krieger et al., 2017). It corresponds to the G5 physiological type (Baden et al., 2016; Goetz et al., 2022) and the C42 transcriptomic cluster (Tran et al., 2019), and is considered the evolutionary ortholog of the primate OFF midget RGC (Hahn et al., 2023). The cell projects a thick, fast-conducting axon to the dorsal lateral geniculate nucleus and superior colliculus. It shows a sustained increase in firing to light decrements with a slow decay time constant of roughly 250 ms and a large receptive field center with weak surround antagonism (Krieger et al., 2017). Its molecular profile includes expression of Spp1 and Neurofilament (Smi32) together with Brn3a (Pou4f1) and Brn3b (Pou4f2), absence of Brn3c (Pou4f3) and Calbindin (Calb1), and strong enrichment of Fes (Krieger et al., 2017; Tran et al., 2019). |
