Spike count correlations for intermediate cylinder disparities. (a) Violin plots show distributions of rSCs for cylinder stimuli with different disparity strengths (p = 0.01; one-way Anova on Fisher’s z). Only disparity values tested on more than 10 recording sites were included; negative disparities were inverted so that each distribution is made up of rSC values obtained from both negative and positive cylinder disparity (i.e. both rotation directions). (b) Bar plots indicate mean rSC values for three stimulus conditions (purple: ambiguous cylinder; grey: unambiguous cylinder; green: random motion). Only sites with strong and matching MU and SU tuning (see Methods) were included. Left panel: Mean rSC values for all sites that were tested with the ambiguous cylinder (zero disparity) and at least one unambiguous cylinder stimulus (i.e. non-zero disparity). Right panel: Mean rSC values for sites that were tested with all three conditions i.e. stimuli. *p < 0.05; **p < 0.01; t-test on Fisher’s z. Error bars indicate s.e.m.
