Firing-rate based network modeling of the dLGN circuit: Effects of cortical feedback on spatiotemporal response properties of relay cells
Fig 5
Effects on relay-cell spatial impulse-response function characteristics from excitatory and inhibitory inputs are opposite.
Top row: dependence on the feedforward inhibition weight wRIG and width aRIG. Middle row: dependence on the feedback inhibition weight and width
. Bottom row: dependence on the feedback excitation weight
and width
. All values are normalized with respect to the case where relay cells only receive feedforward excitation from retinal ganglion cells. The parameters in WG and KRG are kept fixed (see Table 1).
