| Abstract: | We have applied static (SMF) or alternating magnetic fields (AMF) to snail (Helix aspersa) single-unit neurons, in the range of those applied in magnetic stimulation (MS)/transcranial magnetic stimulation (TMS). From the experiments we have performed during the past 10 years, we have collected a blind selection of neurons and their responses to either SMF or AMF. Blind selection means that we do not know the nature of neurons. We do not know whether they are sensitive, motor, secretory, pacemaker, or inter-neurons. We have seen that the behavior of single-unit neurons under SMF/AMF exposure (SMF range: 3 mT–0.7 T; AMF range: 1–15 mT) fits well with the electrophysiologic activity described for mammals and human whole brain under MS/TMS (pulsed magnetic field range: 0.3 mT–2.4 T). The neuron experiments shown here have been aleatorily selected from a collection of about 200 neurons studied. Our results could explain some of the effects described induced in mammal neurons under MS/TMS for clinical purposes. |
