Résumé

The effect of high power nanosecond pulsed electric fields (nsPEF) was examined on the complex neuronal assemblies of intact leech ganglia. The medicinal leech midbody ganglion is a convenient experimental preparation that represents a real neuronal network with neuronal diversity and glial cells. 10 ns pulses of different intensities ranging from 22.5 to 47 kV/cm were applied to the ganglia body and alterations in natural electrical activity of Retzius cells were recorded with sharp glass electrode in a current-clamp mode or multiphoton whole-ganglia imaging with calcium indicators. The lowest nsPEF intensity tested resulted in stimulation of a single action potential (AP) whereas all higher intensities used led to bursts of APs.
