“…In addition, the Alpha-ON sustained RGCs in this particular retinal region differ from the same RGC-type in other regions of the retina as they have a significantly smaller dendritic tree radius and subtend a smaller area of physical space as well as have overlapping receptive fields (Bleckert, Schwartz et al 2014). Taken together, the cellular properties as well as the region in-front of the animal which provides their input are consistent with the requirements for tracking small and mobile targets (Lettvin, Maturana et al 1959, Dean, Redgrave et al 1989, Bleckert, Schwartz et al 2014, Procacci, Allen et al 2020. A recent study has shown that both wide-field and narrow-field neuronal types in the mouse superior colliculus play central roles in the detection and pursuit phases of this pursuit task respectively (Hoy, Bishop et al 2019), and consistent with this, Alpha-ON sustained RGCs having projections to the superior colliculus (Martersteck, Hirokawa et al 2017).…”
