Bar chart showing that the mean amplitude of the incoming volley is reduced post administration (Wilcoxon matched pairs, *P = 0.0156, W = -28, n = 7 mice, error bar: SEM). Line chart to show data from (J), as separate data points for individual mice expressed as a percentage relative to baseline measurements. From this it can be seen that the response was variable across mice with half showing a large reduction and the remaining mice only a minor reduction.
