Model		Effect of mobile phone exposure (900 MHz) and ELF (8.34, 217 Hz) exposure on snail neurons and evaluation of synaptic transmission.
Details		Giant neurons isolated from the mollusk (Helix Pomtia) were exposed to 8.34 or 217 Hz at either 0.1 or 0.6 mT using a helmholtz coil system. Neurons were stimulated by microelectrodes with a train of depolarizing (4 ms) impulses, and finally reached habituation after 1-2 minutes due to exhaustion of the synaptic transmitter molecules in the presynaptic membrane and desensitization of the postsynaptic membrane. If the neurons were exposed to the magnetic field immediately following habituation, however, the giant neurons resumed firing (action potentials). The effect exhibited a dose-response relationship. The authors report the effect as non-thermal and suggest it may indicate interference by RF modulated signals (e.g., GSM) with the normal functioning of the neuron.
