Bar Plot from Scientific Research

Left, changes in spike rates of PPL1-DANs ( e ), induced by CS + and CS - odours in the four different imaging periods. Right, CS + versus CS - bias in evoked responses, relative to pre-training responses ( Methods ); n = 12 flies per cell-type. In c , e , f , data are mean s.e.m. and grey lines show data from individual flies. * P < 0.05, ** P < 0.01; Friedman ANOVA and post-hoc signed-rank tests with Holm Bonferroni correction.
