Dog.0.1

2007 Feb 9
Summary   This is an ON-center spiking unit just like Dog.0.0 except the spike generator is a conductance-driven integrate-and-fire mechanism.

Dog.0.1.mod

Data

Results

The results here were obtained using this response file, which records spikes from an ON-center unit near the center of the stimulus grid.

Sine Tuning

• Spatial frequency
• Temporal frequency
• Contrast
• Static phase

Dynamic Random Stimuli

• Random counter-phase vs. contrast
• Random counter-phase vs. SF

Discussion

There are some differences in the tuning curves for this model and the Poisson spiking Dog.0.0 model. The TF tuning curve for the F1 response is narrower for this I&F model. Also, the F1 contrast response curve for this model is accelerating.
