High noise experiment. Fixation thresholds are shown as dots, saccade thresholds as asterisks. The external noise levels were 2% and 60%, but the coarseness of the external noise was increased to more closely match the grating's spatial frequency, increasing the effectiveness of the noise. As predicted by a gain mechanism, the thresholds fully converged at high noise, indicating a gain reduction mechanism.
