摘要

最近的研究表明,携带神经信号通过大脑的白色物质纤维束通路遵循弯曲的正交网格。这项研究的重点是如何利用微磁刺激(μMS)选择性地激发这些白色物质纤维,微磁刺激是一种新型的神经元刺激,它产生的微涡流能够定向激活神经元。这种新型刺激最显著的特性之一是,μMS 磁场能提供传统电刺激所不具备的独特定向激活神经元的功能。利用基于 SU-8 的光刻技术制造的初始原型表明,这种结构是可以制造出来的。通过电阻计算和电场模拟,对线圈设计进行了优化,以激发大脑的最大焦点和定向神经反应。

Planar figure-8 coils for ultra-focal and directional micromagnetic brain stimulation.

Recently, white-matter fiber tract pathways carrying neural signals through the brain were shown to follow curved, orthogonal grids. This study focuses on how these white-matter fibers may be selectively excited using micromagnetic stimulation (μMS), a new type of neuronal stimulation, which generates microscopic eddy currents capable of directionally activating neurons. One of the most remarkable properties of this novel type of stimulation is that the μMS fields provide unique directional activation of neuronal elements not seen with traditional electrical stimulation. An initial prototype built with SU-8 based photolithography technology shows that the structure can be fabricated. The coil design was optimized through electrical resistance calculations and electric field simulations to elicit the brain's maximal focal and directional neural responses.
