多年来，神经科学家已经广泛使用插入皮层的金属微电极来记录来自神经组织的神经信号，并向神经组织提供电刺激。近来，对于在皮层内植入电极阵列以用于刺激和记录两者的需求已经迅速增加。我们正在开发主动浮动微电极阵列（AFMA），该阵列预期用作多电极皮质界面，同时最大限度地减少从阵列到硬膜外电路或连接器的导线数量。当与无线模块相结合时，这些新的微电极阵列应该允许在自由漫游的动物中进行模拟和记录。本文主要讨论了第一代AFMA的设计、制造和封装。我们的长期愿景是一种无线传输电极系统，用于自由漫游动物的刺激和记录，该系统使用一系列模块化有源植入式电极阵列。
Neuroscientists have widely used metal microelectrodes inserted into the cortex to record neural signals from, and provide electrical stimulation to, neural tissue for many years. Recently, the demand for implanting electrode arrays within the cortex, for both stimulation and recording, has rapidly increased. We are developing Active-floating-micro-electrode-arrays (AFMA) that are intended for use as a multielectrode cortical interface while minimizing the number of wires leading from the array to extra-dural circuitry or connectors. When combined with a wireless module, these new microelectrode arrays should allow for simulation and recording within free-roaming animals. This paper mainly discusses the design, fabrication, and packing of the first generation AFMA. Our long-term vision is a wireless-transmission electrode system, for stimulation and recording in free-roaming animals, which uses a family of modular active implantable electrode arrays.
