Virtual Retina

Keywords: Neurosciences - Simulation - Biology

Functional Description Virtual Retina [14] allows large-scale simulations of biologically-plausible retinas, with customizable parameters. Virtual Retina has been shown to reproduce a wide range of experimental data from salamander, cat and primate retinas [14] , and has been used in several theoretical studies [79] , [82] , [83] , [56] . It has recently been shown to predict spikes in a mouse retina more accurately than linear-nonlinear (LN) models [93] . The underlying model includes a non-separable spatio-temporal linear model of filtering in the Outer Plexiform Layer, a shunting feedback at the level of bipolar cells, and a spike generation process using noisy leaky integrate-and-fire neurons to model retinal ganglion cells (RGCs). All parameters for the different stages of the model are customizable so that the visual field can be paved with different RGC types.
