Choice probabilities and spike count correlations. (a) Scatter plot of SU CP and SU-MU rSC. Each dot represents a SU that showed strong and matching cylinder rotation tuning and for which a CP value could be measured (see Methods; n = 39). Red dots indicate SUs with a significant CP (p < 0.05; cluster based permutation test). Black solid line indicates a linear fit to all data points with 95% confidence interval (dashed lines) and displayed correlation coefficient and associated p-value stem from the Pearson correlation. (b) Average rCCG for subpopulations of sites split by the median CP associated with the SU (median CP = 0.68). Solid line: CP > 0.68; Dashed line: CP < 0.68. Error bars indicate the s.e.m. Horizontal lines indicate corresponding average rSC values. *p < 0.05; un-paired t-test.
