    • A neurostimulator system (170) stimulates excitable muscle or neural tissue through multiple electrodes (E1, E2, ... En) fast enough to induce stochastic neural firing, thereby acting to restore "spontaneous" neural activity. The type of stimulation provided by the neurostimulator involves the use of a high rate, e.g., greater than about 2000 Hz, pulsitile stimulation signal generated by a high rate pulse generator (172). The stream of pulses generated by the high rate pulse generator is amplitude modulated in an output driver circuit (176) with control information, provided by a modulation control element (178). Such amplitude-modulated pulsitile stimulation exploits the subtle electro physiological differences between cells comprising excitable tissue in order to desynchronize action potentials within the population of excitable tissue. Such desynchronization induces a wider distribution of population thresholds, as well as a wider electrical dynamic range, thereby better mimicking biological recruitment characteristics.
    • 神经刺激器系统(170)通过多个电极(E1,E2,... En)以足够快的速度刺激可兴奋的肌肉或神经组织,以诱导随机神经激发,从而起到恢复“自发”神经活动的作用。 由神经刺激器提供的刺激类型涉及使用高速率,例如大于约2000Hz的由高速率脉冲发生器(172)产生的脉动刺激信号。 由高速脉冲发生器产生的脉冲流在具有由调制控制元件(178)提供的控制信息的输出驱动器电路(176)中被幅度调制。 这种调幅脉动刺激利用包含可兴奋组织的细胞之间的细微电生理差异,以便使可兴奋组织群体内的动作电位失去同步。 这种失步导致人口阈值的更广泛分布,以及更宽的电动态范围,从而更好地模拟生物招募特征。
