Microrecording of Neural activity with frameless stereotaxy and on-demand stimulation system

图像引导系统的发展使得无框架立体定向脑深部电刺激手术成为可能。与立体定向靶向一样，靶点的神经生理学识别也很重要。多道微记录是确定电极最佳位置的有效技术。这是我们使用Nexframe无框架立体定向与Ben's Gun多道显微记录驱动器的经验的报告，我们研究了该系统的准确性，有用性和缺点。因此，该系统的精度类似于基于帧的立体定位。然而，狭窄的手术野是多个电极插入的缺点。到目前为止，我们不认为这种技术在其目前的状态可以取代传统的框架为基础的立体定向手术。

The development of image-guided systems rendered it possible to perform frameless stereotactic surgery for deep brain stimulation (DBS). As well as stereotactic targeting, neurophysiological identification of the target is important. Multi-tract microrecording is an effective technique to identify the best placement of an electrode. This is a report of our experience of using the Nexframe frameless stereotaxy with Ben's Gun multi-tract microrecording drive, and we study the accuracy, usefulness and disadvantages of the system. As a result, the accuracy of this system is similar to that of frame-based stereotaxy. However, the narrow surgical field is a disadvantage for multiple electrodes insertion. Thus far, we do not consider that this technology in its present state can replace conventional frame-based stereotactic surgery.
