The MEA (multielectrode array) system was used to record electrical responses of intact and halved traps, and other trap-free tissues of two aquatic carnivorous plants, Aldrovanda vesiculosa and Utricularia reflexa. Spontaneous generation of spikes with quite uniform shape, propagating across the recording area, has been observed for all tested organs. In the analysis of the electrical network, higher richer synchronous activity was observed relative to other plant species and organs previously described in the literature: the time intervals between the synchronized clusters (the inter-spike intervals) create organized patterns and the propagation times vary non-linearly with the distance due to this synchronization. More complex electrical activity was found in traps than in trap-free organs, supporting the hypothesis that the nature of the electrical activity may reflect the anatomical and functional complexity of different organs.
