Spectral Characteristics of Firing Pattern in Retinal Ganglion Cells
This paper studies the firing patterns of retinal ganglion cells (RGCs) with frequency-domain approach based on partial directed coherence (PDC) which reffects a frequency-domain representation of Granger causality. The results suggest that the PDC of the RGCs spike trains in response to natural movie has significant frequency dependence; while it doesnt change much across neighboring frequency band under the pseudo-random checker-board stimulus. Possible mechanisms underlying these distinct features are discussed.
