Abstract

This study examines the relationship between chondroitin sulfate, proteinoids, and computational neuron models, with a specific emphasis on the Izhikevich neuron model. We investigate the effect of chondroitin sulfate-proteinoid complexes on the behavior and dynamics of simulated neurons. Through the use of computational simulations, we provide evidence that these biomolecular components have the power to regulate the responsiveness of neurons, the patterns of their firing, and the ability of their synapses to change within the Izhikevich architecture. The findings suggest that the interactions between chondroitin sulfate and proteinoid cause notable alterations in the dynamics of membrane potential and the timing of spikes. We detect adjustments in the features of neuronal responses, such as shifts in the thresholds for firing, alterations in spike frequency adaptation, and changes to bursting patterns. The findings indicate that chondroitin sulfate and proteinoids may have a role in precisely adjusting neuronal information processing and network behavior. This study offers valuable information about the complex connection between the many components of the extracellular matrix, protein-based structures, and the functioning of neurons. In addition, our analysis of the proteinoid-chondroitine system using game theory uncovers a significant Prisoner's Dilemma scenario. The system's inclination toward defection, due to the appeal of cheating and the significant penalty for cooperation, with a mean voltage of -9.19 mV, indicates that defective behaviors may prevail in the long term dynamics of these neuronal interactions.

神经元模型中的硫酸软骨素和类蛋白。
本研究考察了硫酸软骨素、类蛋白和计算神经元模型之间的关系,特别强调了Izhikevich神经元模型。我们研究了硫酸软骨素-类蛋白复合物对模拟神经元行为和动力学的影响。通过计算模拟的使用,我们提供了证据,证明这些生物分子成分有能力调节神经元的反应性,它们的放电模式,以及它们的突触在Izhikevich结构内改变的能力。研究结果表明,硫酸软骨素和类蛋白之间的相互作用引起膜电位动力学和峰值时间的显著改变。我们检测到神经元反应特征的调整,如放电阈值的变化,尖峰频率适应的改变,以及爆发模式的变化。研究结果表明,硫酸软骨素和类蛋白可能在精确调节神经元信息处理和网络行为中起作用。这项研究提供了关于细胞外基质、蛋白质结构和神经元功能之间的复杂联系的有价值的信息。此外,我们利用博弈论对类蛋白-软骨素系统的分析揭示了一个重要的囚徒困境情景。由于欺骗的吸引力和合作的显著惩罚,系统倾向于背叛,平均电压为-9.19 mV,表明缺陷行为可能在这些神经元相互作用的长期动力学中普遍存在。

期刊介绍: ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
