Firing-rate based network modeling of the dLGN circuit: Effects of cortical feedback on spatiotemporal response properties of relay cells
Fig 12
Mixed feedback: Delayed inhibitory feedback gives oscillatory responses, delayed excitatory feedback more monophasic responses.
Two leftmost panels: temporal impulse-response function with mixed excitatory and inhibitory feedback, where feedforward inhibition also is included. Two rightmost panels: parameter dependence of two impulse-response measures tpeak and biphasic index IBP. See Fig 11 caption for details. Default parameters have been used for fixed parameters (see Table 1).
