This study examines a new approach to hybrid neuromorphic devices by studying the impact of omeprazole-proteinoid complexes on Izhikevich neuron models. We investigate the influence of these metabolic structures on five specific patterns of neuronal firing: accommodation, chattering, triggered spiking, phasic spiking, and tonic spiking. By combining omeprazole, a proton pump inhibitor, with proteinoids, we create a unique substrate that interfaces with neuromorphic models. The Izhikevich neuron model is used because it is computationally efficient and can accurately simulate the various behaviours of cortical neurons. The results of our simulations show that omeprazole-proteinoid complexes have the ability to affect neuronal dynamics in different ways. This suggests that they could be used as adjustable components in bio-inspired computer systems. We noticed a notable alteration in the frequency of spikes, patterns of bursts, and rates of adaptation, especially in chattering and triggered spiking behaviours. The findings indicate that omeprazole-proteinoid complexes have the potential to serve as adaptable elements in neuromorphic systems, presenting novel opportunities for information processing and computation that have origins in neurobiological principles. This study makes a valuable contribution to the expanding field of biochemical neuromorphic devices and establishes a basis for the development of hybrid bio-synthetic computational systems.
这项研究通过研究奥美拉唑-蛋白原复合物对 Izhikevich 神经元模型的影响,考察了混合神经形态器件的一种新方法。我们研究了这些代谢结构对五种特定的神经元发放模式的影响:适应、喋喋不休、触发脉冲、相脉冲和紧张性脉冲。我们将质子泵抑制剂奥美拉唑与蛋白原结合,创造了一种与神经形态模型接口的独特基质。之所以选择 Izhikevich 神经元模型,是因为它计算效率高,可以准确模拟皮质神经元的各种行为。我们的模拟结果表明,奥美拉唑-蛋白原复合物能够以不同的方式影响神经元动力学。这表明它们可以用作仿生计算机系统中的可调组件。我们注意到,在尖峰频率、爆发模式和适应率方面,特别是在喋喋不休和触发脉冲行为方面,有明显的变化。这些发现表明,奥美拉唑-蛋白原复合物有可能成为神经形态系统中的自适应元件,为基于神经生物学原理的信息处理和计算提供新的机会。这项研究为生化神经形态器件这一日益扩展的领域做出了重要贡献,并为混合生物合成计算系统的发展奠定了基础。
