Neuronal and model responses to anticorrelated stimuli, for the two example cells. A, B, The prediction of the model of the disparity-tuning function for correlated (Corr, filled) and anticorrelated (Anticorr, open) RLSs (left). The scatter plot of the responses between same disparity (right). The slope of the regression line (dashed) is the amplitude ratio of the two tuning functions. The predicted slopes were both close to −1 (−0.69, −1.1). C, D, Disparity tuning estimated from responses to noise stimuli. The regression slopes were −1.0 in both cells, indicating no attenuation of response with anticorrelation. E, F, The actual response of the cell to correlated (filled) and anticorrelated (open) RLSs in a traditional tuning curve. The regression slopes (−0.45, −0.48) were lower than in A and B.
