Sigmoid

converts raw activity into signed firing-rate deviation; adaptive feedback uses the corresponding nonnegative physical firing rate.

Steepness Threshold

Raw activity A =

S(A)	=	R(A)	−	R(0)
Model response	=	Absolute firing	−	Baseline
	=		−

Moving the threshold also changes the baseline that is subtracted. The model responds to differences from zero activity, not absolute firing.

Local Orientation Kernel Strength

local coupling across different orientations at the same position.

Preferred wavelength Surround ratio DC balance

DC balance=1 gives the paper's equal positive and negative lobe mass. Other values deliberately add a uniform lateral bias.

Anti-Lateral Kernel Strength

Shares the straight spatial kernel above but reads the orientation channel 90° away.

Perpendicular Kernel Strength
