摘要

为了加深我们对电穿孔的理解,并优化 1 kHz 至 100 MHz 频率范围内的脉冲,从而最大限度地减少肌肉收缩等副作用,我们引入了一种新型电学模型,该模型采用完全块状元素的二维表示结构。该模型巧妙地囊括了活细胞阻抗变化的复杂动态。该模型的一个显著特点是,它能够解读活细胞内跨膜电位在不同方向上的分布。这一点至关重要,尤其是在电穿孔和细胞刺激等情况下,对电位梯度的精确了解至关重要。此外,利用霍奇金-赫胥黎(HH)模型对所提出的电学模型进行扩充还引入了一个额外的维度。这种整合增强了模型的功能,特别是能够探索肌肉细胞刺激和动作电位的产生。这一更广泛的范围增强了模型的实用性,有助于全面研究外部电场影响下错综复杂的细胞行为。

Characterizing parameters and incorporating action potentials via the Hodgkin-Huxley model in a novel electric model for living cells.

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.
