The data was used for evaluation of the approach for overcoming temporal dispersion in unmyelinated neves designed in the previously performed modelling study. ", "abstract": "This study was conducted to evaluate a new method for measuring impedance changes far from the stimulus where CAPs are dispersed. We used an ex vivo preparation of porcine subdiaphragmatic nerves with four multielectrode cuffs. Each stuied nerve was subjected to 10 Hz trains of stimuli lasting 0.6 s (with 5 s between trains) applied to a pair of electrodes on the first cuff, and AC curent  was applied at a range of frequencies through a pair of electrodes on the third or fourth cuff placed approximately 15 and 20 cm from the first one. Voltages were recorded on all electrodes in the respect to the last electrode on the last cuff. Each recording lasted 30 minutes. It was shown that stimulation of the nerve by trains of stimuli and processing the data as whole trains allowed measurement of impedance changes further from the onset than it was possible with a traditional continuous stimulation and averaging of consecutive spikes."}}
