Abstract

Characterizing parameters and incorporating action potentials via the Hodgkin-Huxley model in a novel electric model for living cells Bougandoura O, Achour Y, Zaoui A, Starzyński J. Characterizing parameters and incorporating action potentials via the Hodgkin-Huxley model in a novel electric model for living cells. Electromagn Biol Med. 2024 Jul 2;43(3):187-203. doi: 10.1080/15368378.2024.2372107. Abstract To enhance our understanding of electroporation and optimize the pulses used within the frequency range of 1 kHz to 100 MHz, with the aim of minimizing side effects such as muscle contraction, we introduce a novel electrical model, structured as a 2D representation employing exclusively lumped elements. This model adeptly encapsulates the intricate dynamics of living cells' impedance variation. A distinguishing attribute of the proposed model lies in its capacity to decipher the distribution of transmembrane potential across various orientations within living cells. This aspect bears critical importance, particularly in contexts such as electroporation and cellular stimulation, where precise knowledge of potential gradients is pivotal. Furthermore, the augmentation of the proposed electrical model with the Hodgkin-Huxley (HH) model introduces an additional dimension. This integration augments the model's capabilities, specifically enabling the exploration of muscle cell stimulation and the generation of action potentials. This broader scope enhances the model's utility, facilitating comprehensive investigations into intricate cellular behaviors under the influence of external electric fields. pubmed.ncbi.nlm.nih.gov

Main findings

The authors propose a novel 2D lumped-element electrical model intended to represent living-cell impedance variation and to estimate transmembrane potential distribution across orientations. They further integrate the Hodgkin-Huxley model to enable exploration of muscle cell stimulation and action potential generation under external electric fields.

Outcomes measured

• cell impedance variation dynamics (modeled)
• transmembrane potential distribution across orientations (modeled)
• muscle cell stimulation and action potential generation via Hodgkin-Huxley integration (modeled)
• pulse optimization to minimize side effects such as muscle contraction (modeling aim)

Limitations

• Appears to be a modeling/engineering study; no experimental population or sample size is described in the abstract.
• No quantitative results, validation data, or specific pulse/exposure parameters are provided in the abstract.
