GaborME.0.0.s2.tq

2008 Aug 2

Summary   This is a spatially double, temporally quarter-size variant of the standard GaborME.0.0 model. The spatial Gabor filter was constructed using a Gaussian SD that is twice as wide and a spatial frequency that is half that of the standard model. The temporal Gabor filter was constructed using a Gaussian SD that is one quarter as long and a temporal frequency that is four times that of the standard model.

GaborME.0.0.s2.tq.mod

Results

Results are similar to those for GaborME.0.0, except that the peak of the SF tuning curves is one octave lower, and that of the TF tuning curve is two octaves higher.

Discussion

The gain before the Poisson spike generation is the same as that of the standard model, because the factor of two increase of the linear filter in two spatial dimensions balances the quartering of the temporal dimension.
