ENG recordings in response to mechanical stimulation

This data supports the journal paper titled 'Influence of nerve cuff channel count and implantation site on the separability of afferent ENG'. Electroneurogram signals recorded from 16-channel and 3 -channel cuff electrodes placed on the sciatic nerve of Sprague Dawley rats. The recordings were made in response to three types of mechanical stimulation, namely, proprioception, touch and nociception. The data files include synchronisation comments and signals that indicate when a stimulus was applied and what the stimulus was. Proprioceptive responses were recorded in response to a servo motor moving the foot to one of 6 different angles. Touch responses were recorded in response to heel of the foot being touched with different Von Frey fibres. Finally, Nociception responses were recorded in response to the foot being pinched using a pair of forceps either on the heel, or the outer toe.本数据集支持题为《神经袖套电极通道数与植入位点对传入神经电图（electroneurogram, ENG）可分离性的影响》的期刊论文。实验采用放置于斯普拉格-道利大鼠（Sprague Dawley rats）坐骨神经上的16通道与3通道神经袖套电极，记录传入神经电图信号。本次记录针对三类机械刺激展开，分别为本体感觉、触觉与伤害性感受刺激。数据文件包含同步标注信息，以及用于标记刺激施加时刻与刺激类型的信号。其中，本体感觉响应的记录方式为：通过伺服电机将大鼠足部移动至6种不同角度，采集对应神经信号；触觉响应的记录方式为：使用不同规格的冯·弗雷纤维（Von Frey fibres）触碰大鼠足跟，采集相应神经信号；伤害性感受响应的记录方式为：使用镊子分别夹捏大鼠足跟或外侧脚趾施加伤害性刺激，同步记录对应的神经信号。
