Abstract

A driven shield for a nine-barrel micropipette containing a carbon fiber recording electrode in the center barrel is described. Two of the nine surrounding micropipettes were used as a driven shield channel to reduce capacitance between the recording electrode and the brain tissue. This method facilitates recording of single neuron activity, even in deep areas of the monkey brain, such as the amygdala and lateral hypothalamic area.

摘要

描述了一种用于九管微量移液器的驱动屏蔽装置，其中心管中装有碳纤维记录电极。九个周围微量移液器中的两个用作驱动屏蔽通道，以减少记录电极与脑组织之间的电容。这种方法有助于记录单个神经元活动，即使在猴脑的深部区域，如杏仁核和下丘脑外侧区。
