摘要

在急性实验中,在大鼠腓神经内插入二维24通道线微电极阵列。阵列中的电极位于6 × 4电极的规则网格上;电极间距为120 /spl mu/m。对于阵列中的每个电极,记录了相应的指长伸肌(EDL)的抽搐力恢复曲线。得到了一套完整的24条招募曲线,这些曲线的形状在阵列中电极之间是不同的。这支持了先前的发现,即在不同的神经内位置刺激电极有不同的运动单元招募顺序。

Intraneural stimulation using 2D wire-microelectrode arrays. I. Experimental results
A two-dimensional 24-channel wire-microelectrode array was inserted into the peroneal nerve of the rat during acute experiments. The electrodes in the array are on a regular grid of 6 by 4 electrodes; inter-electrode spacing is 120 /spl mu/m. For each of the electrodes in the array the corresponding twitch-force recruitment curve was recorded from the extensor digitorum longus muscle (EDL). A complete set of 24 recruitment curves is presented The shape of the recruitment curves varies among the electrodes in the array. This supports previous findings which suggest a different motor unit recruitment order for stimulating electrodes at different intraneural positions.
