Regression coefficients of outcome history of previous trial contributing to the neural response to the go stimulus in the Stable and Re-stable session ( n = 493 cells from 5 mice). The symbol * denotes a significant difference compared to 0 (two-sided one-sample Wilcoxon signed-rank test). The symbol # denotes the significant difference of coefficients of the previous trial between the Stable and Re-stable session (two-sided Wilcoxon rank-sum test). ** P < 10 −2 , *** P < 10 −3 , # P < 0.05, ## P < 10 −2 , ### P < 10 −3 . Data ( c , h , j ) are presented as mean ± s.e.m. or ( d ) box plots (center line, median; box limits, upper and lower quartiles; whiskers, 1.5 × interquartile range). Statistical details are presented in Supplementary Table 1 . Source data are provided as a Source data file.
