Effects of the LqhαIT toxin on the cockroach connective nerve activity and their modification by the ELF-EMF exposure. The extracellular recordings of the connective nerve activity as a response to the circus mechanostimulation (marked by black arrow) in: (a) control, (b) after the toxin (5 × 10⁻⁸ M) application, (c) after the exposure to ELF-EMF – 0.7 mT, (d) after the toxin (5 × 10⁻⁸ M) administration and exposure to ELF-EMF – 0.7 mT. (e) The normalized activity of the connective nerve during the experiment in the control conditions (white and grey circles), after the toxin application (white circles) and after exposure to ELF-EMF (grey circles). (f) The normalized connective nerve activity after the toxin application and exposure to ELF-EMF at the same time. On e and f arrow corresponds to the application of the toxin. Note: the scheme of the experimental protocol is shown on Fig. 2. Data are presented as mean values ± standard errors (S.E. are in most cases inside the symbols, n = 15)
