ParameterValueDescription
D24MT directional tuning quantization of 15°
R1024Number of MSTd templates spaced along a regular grid across the visual field
s4Extent that habituation of MT transmitter gates generalizes to MT cells with similar direction preferences (65° SD)
k0.75Rate of temporal accumulation in MT transmitter gates
r0.01Spatial extent (20° SD) of interaction between MSTd and MT cells (feedforward and feedback)
λ675Gain on feedforward MSTd signal from MT
h2Spread of inhibition toward MT cells tuned to directions neighboring the expected direction (45° SD) from the template of MSTd cell sending the feedback signal
