Occupational exposure limit values (ELVs) for body internal electric fields can be derived from thresholds for action potential generation. These thresholds can be calculated with electrostimulation models. The spatially extended nonlinear node model (SENN) is often used to determine such thresholds.

Article Synopsis
- Temporal interference (TI) stimulation involves the interaction of two sinusoidal electric fields with different frequencies, revealing that neuronal cells respond differently to TI compared to purely sinusoidal signals.
- This study employs computational models to simulate how different neuron models—Hodgkin-Huxley, Frankenhaeuser-Huxley, and various integrate-and-fire models—respond to these signals, finding that HH and FH models accurately replicate observed neural responses while IF models do not.
- Key findings indicate that modifications to ion gate dynamics in the FH model can affect firing thresholds and highlight the importance of ion channels in shaping neuronal responses, contributing valuable insights into the biophysics of neurons and the mechanisms of TI stimulation.

Temporal interference (TI) stimulation is a technique in which two high frequency sinusoidal electric fields, oscillating at a slightly different frequency are sent into the brain. The goal is to achieve stimulation at the place where both fields interfere. This study uses a simplified version of the Hodgkin - Huxley model to analyse the different parameters of the TI-waveform and how the neuron reacts to this waveform.
