GaborME.0.0.sh

2008 Jul 28

Summary   This is a spatially half-size variant of the standard GaborME.0.0 model. The spatial Gabor filter was constructed using a Gaussian SD that is 1/2 as wide and a spatial frequency that is double that of the standard model.

GaborME.0.0.sh.mod

Results

Results are similar to those for GaborME.0.0, except that the SF tuning peaks one octave higher.

Discussion

The gain before the Poisson spike generation is set to 4 times that of the standard model, to account for the factor of two shrinkage of the linear filter in two spatial dimensions. The RF is small at the spatial resolution of the model (0.1 deg/pix), but is well within the Nyquist limit.
