GaborME.0.0.s2.th

2008 Jul 28

Summary   This is a spatially and temporally double-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 1/2 that of the standard model. The temporal Gabor filter was constructed using a Gaussian SD that is 1/2 as long and a temporal frequency that is double that of the standard model.

GaborME.0.0.s2.th.mod

Results

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

Discussion

The gain before the Poisson spike generation is set to 1/2 times that of the standard model, to account for the factor of two expansion of the linear filter in two spatial dimensions and the halving of the temporal dimension.
