Table 6.

Modifications of spike latency between the first and the last AP of each train at the different frequencies and animal age. The values are expressed as % of latency modification compared to the first AP.

Frequency	10 Hz	20 Hz	40 Hz	80 Hz	Friedman between frequencies (P)
P15	8 ± 2%	15 ± 3%	22 ± 3%	28 ± 3%	<0.001
P38	1 ± 0.4%	2 ± 0.8%	8 ± 2%	33 ± 3%	<0.001
P-value P15 vs. P38	<0.001	<0.001	<0.001	0.33	###

Bold indicates statistically significant difference.
