Zusammenfassung: | Transcranial Magnetic Stimulation (TMS) is a widely used non-invasive brain stimulation method. However, its mechanism of action and the neural response to TMS are still poorly understood. Multi-scale modeling can complement experimental research to study the subcellular neural effects of TMS. At the macroscopic level, sophisticated numerical models exist to estimate the induced electric fields. However, multi-scale computational modeling approaches to predict TMS cellular and subcellular responses, crucial to understanding TMS plasticity inducing protocols, are not available so far.
We develop an open-source multi-scale toolbox Neuron Modeling for TMS (NeMo-TMS) to address this problem.
NeMo-TMS generates accurate neuron models from morphological reconstructions, couples them to the external electric fields induced by TMS, and simulates the cellular and subcellular responses of single-pulse and repetitive TMS.
We provide examples showing some of the capabilities of the toolbox.
NeMo-TMS toolbox allows researchers a previously not available level of detail and precision in realistically modeling the physical and physiological effects of TMS.
•We developed a new toolbox (NeMo-TMS) to simulate the cellular and subcellular activity of single neurons in response to (repetitive) TMS.•TMS-induced electric fields from the macroscopic models are coupled with a morphologically realistic neuron model to simulate the membrane potential and the spiking pattern.•Membrane potentials are used to model the voltage-gated calcium dynamics important for understating neuronal plasticity.•All necessary codes can be found in an open-source repository (https://github.com/OpitzLab/NeMo-TMS). |
