Figure 6

Histogram illustrating the distribution of waiting time autocorrelation values in the spiking profiles induced by Nod factor (black), CO4 (grey) and fungal exudate (white). The percentage of nuclei where autocorrelation value is significantly negative (< −0.2) or positive (> +0.2) are shown in the Figure. Waiting time autocorrelation values for CO4– and exudate-induced spiking display a maximum in the negative range, whereas Nod factor-induced spiking is characterized by a prevalence of positive autocorrelation values. Letters indicate statistically significant differences as highlighted by the Pearson χ² test.
