Mean ± SEM (number of cells) are presented for Nb+/ChAT+, Nb+/ChAT− “on”, and Nb+/ChAT− “off” cell groups. The three groups were compared by ANOVA. With a main effect of cell group indicated by *p < 0.05, post hoc comparisons were performed, using Fisher's Least Significant Difference test (according to which
†
indicates significant difference relative to the Nb+/ChAT+ cell group and § to significant differences relative to the Nb+/ChAT− “on” cell group).
