电生理记录和刺激是手术和治疗干预期间功能映射以及捕获完整人脑中细胞活动的金标准。探测人脑活动的一个关键组件是电极接触处的界面材料，该界面材料在测量系统中以电化学方式将大脑信号转换为自由电荷载流子。在这里，我们总结了最先进的电极阵列系统在翻译的背景下，用于记录和刺激人脑活动。我们利用多种电极材料的参数研究来阐明不同水平的适用性，以实现高信噪比的电生理记录以及安全的电生理刺激输送。我们讨论了电极缩放对记录和刺激的影响，以追求高空间分辨率，通道计数电极接口，描绘决定电极性能的电极-组织电路组件。最后，我们总结了最近的努力，在connectorization和包装高通道计数电极阵列，并提供了一个简短的说明，努力走向无线神经元监测系统。
Electrophysiological recording and stimulation are the gold standard for functional mapping during surgical and therapeutic interventions as well as capturing cellular activity in the intact human brain. A critical component probing human brain activity is the interface material at the electrode contact that electrochemically transduces brain signals to and from free charge carriers in the measurement system. Here, we summarize state-of-the-art electrode array systems in the context of translation for use in recording and stimulating human brain activity. We leverage parametric studies with multiple electrode materials to shed light on the varied levels of suitability to enable high signal-to-noise electrophysiological recordings as well as safe electrophysiological stimulation delivery. We discuss the effects of electrode scaling for recording and stimulation in pursuit of high spatial resolution, channel count electrode interfaces, delineating the electrode–tissue circuit components that dictate the electrode performance. Finally, we summarize recent efforts in the connectorization and packaging for high channel count electrode arrays and provide a brief account of efforts toward wireless neuronal monitoring systems.
