Comparison of burst ratio and number of spikes within burst between groups. The burst ratio of neurons from diabetic rats (n = 26) is significantly lower than that of control rats (n = 59, P < 0.001, Mann-Whitney test). Decrease of the number of spikes within bursts in diabetic rats was also observed (P < 0.001, Mann-Whitney test). Compared to that of diabetic rats, APP 17-mer peptide increased the burst ratio and number of spikes within bursts (n = 35, P < 0.05 for burst ratio; P < 0.001 for number of spikes within bursts, Mann-Whitney test) but still had significant difference with control rats (P < 0.01, Mann-Whitney test, for burst ratio; P < 0.001 for number of spikes within bursts). “n” represents number of neurons.
