Stimulators were driven with square-wave signals from an A-M Systems Model 2100 Isolated Pulse Stimulator. For FA imaging only, stimulation alternated between contralateral forelimb (cFL) and contralateral hindlimb (cHL) for a total of 40 trials of stimulation of each limb. This range of threshold criteria was tested against manual The pin and electrode cable wire designations can be found in the "Operating Instructions" section in this manual. STIMULUS: This 5-pin connector allows for external signals to be applied to the electrode. For example, stimuli can be applied with a Model 2100 Isolated Pulse Stimulator. Rectangular biphasic pulses (25 Hz, 0.5 ms) with amplitude of 7 V were delivered by an electrical stimulator (Isolated Pulse Stimulator Model 2100, A-M Systems, Sequim, WA). To confirm the inserted position of the bipolar electrodes, we placed a microneedle in the same position as the electrodes and injected 4% Evans blue dye. The Open Triangle marks the stimulation pulse. (duration 200 μs, amplitudes 50 μA to 2.5 mA) were generated by a Model 2100 Isolated Pulse Stimulator from A-M Systems. Supporting Information.

(2000b) using the rat femoral nerve injury model. This approach is often referred to as brief electrical stimu-lation (ES) and consists of a 1-hour application of low-frequency (20 Hz) electric current to the proximal nerve stump of the severed nerve prior to surgical reconstruction. Stimulation leads to (1) depolarization of the motoneuron isolated pulse stimulator (model 2100; A-M Systems). Individual pulses were400 slong,ranginginamplitudefrom15to40 A.Thefrequency of stimulation ranged from 10 to 20 Hz, and the train duration ranged from 300 to 1000 ms for a total of 3-20 stimuli. For each bird, the parameters were set to maximize the probability and number of vocal- Model 2100 Accessories All Constant Current / Constant Voltage sources making use of optical isolation will have a small leakage current. This current is typically zeroed out using baseline, but can be easily filtered using an RC circuit, provided the stimulation protocol does not have long DC components. The Model 3800 MultiStim 8-channel Programmable Stimulator can produce pulses ranging in duration from one microsecond to 12 days. Amplitudes can be set to range from -10 V to 10 V, with 1 mV resolution. When combined with the Model 3820 External SIU, the voltage pulse can be scaled and converted into constant current, with output ranges of The effect of paired pulse stimulation is expressed as amplitude of second response/amplitude of first response x 100. Stimulation parameters for the induction of long-term potentiation (LTP) were base
