Transcranial magnetic stimulation (TMS) is used for neuromodulation of the human brain. However, the technique is not widely used for small animal models. Here, we propose millimeter-sized coils for brain stimulation of small animals. To estimate the electric field distributions of TMS coils, we performed magnetic flux density measurements and computer simulation using a simplified model combining a mouse head and a TMS coil. Our results indicate the millimeter-sized TMS coils produce electrical field with sufficient magnitude to activate the cortex under the skull in vivo. © 2021 Institute of Electrical Engineers of Japan.

表征用于小动物经颅磁刺激的毫米级线圈：磁芯的比较

经颅磁刺激 (TMS) 用于人脑的神经调节。然而，该技术并未广泛用于小动物模型。在这里，我们提出了用于小动物脑刺激的毫米级线圈。为了估计 TMS 线圈的电场分布，我们使用结合了鼠标头和 TMS 线圈的简化模型进行了磁通密度测量和计算机模拟。我们的结果表明，毫米大小的 TMS 线圈产生的电场强度足以激活体内颅骨下的皮层。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
