The effects of the LqhαIT toxin on cockroach cercal nerve activity and their modification by ELF-EMF exposure. The extracellular recordings of the cercal 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 LqhαIT toxin (5 × 10−8 M) application and exposure to the ELF-EMF – 0.7 mT. (e) Normalized bioelectrical activity of the cercal nerve during the experiment in the control conditions (white and grey circles), after toxin application (white circles) and after exposure to ELF-EMF (grey circles). (f) Normalized activity of the cercal nerve activity after the LqhαIT toxin application and the exposure in the 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; standard errors are in most cases inside the symbols, n = 15
