Firing-rate based network modeling of the dLGN circuit: Effects of cortical feedback on spatiotemporal response properties of relay cells
Fig 2
Schematic overview of the present eDOG model.
Cell types are: retinal ganglion cells (G), dLGN relay cells (R), and cortical cells (C). Each cell type corresponds to a two-dimensional layer (or population) of identical cells (see Fig 1). Note that only one cortical population is shown for each pathway even though an arbitrary number of cortical populations is considered. Unlike the feedforward projection, the feedback is cross-symmetry, i.e., the activity of ON-center relay cells are affected both by ON and OFF-center cortical cells. The OFF-center dLGN relay cells are assumed to receive the same input as the corresponding ON-center dLGN relay cells with opposite sign. Solid lines represent explicitly included connections in the eDOG model, while dashed lines represent connections included implicitly.
