Up: Nodes’ density in sample areas in control nerves and nodes’ density in sample areas in stimulated nerves. NS non-stimulated (control nerve), S stimulated nerve, s section, a sample area (n integer, number of nerve, section and sample respectively); Down: Node density of “non stimulated” and “stimulated” sample groups represented as a boxplot including average values and standard deviation.
