Figure 5From: Selective modulation of chemical and electrical synapses of Helix neuronal networks during in vitro developmentInter spike interval (ISI) characterization of Helix networks. (A, B) ISI distribution relative to the stimulation phases for (A) C1 and (B) B2 neurons. The treatment with 5-HT and KCl is coded with gray and black colors, respectively. Bin width = 20 ms. (C, D) Temporal peak position of the ISI distributions relative to C1 (C) and B2 (D) neurons, respectively. (Kruskal-Wallis, non-parametric test, P < 0.01)Back to article page
