Easy to use, programmable electrical stimulation
The StimJim is a dual-channel electrical stimulator. It allows the generation of arbitrary current or voltage waveforms for extracellular electrical stimulation or electrode activation. Its galvanically isolated outputs greatly reduce electrical stimulation artifacts during concurrent electrophysiological recordings. The device also features an electrode discharge circuit which is automatically activated between pulses to further reduce stimulation artifacts and prevent tissue damage due to charge imbalances. Further, integrated circuitry measures all stimulus currents and voltages so that the user can be sure of correct stimulation delivery during experimentation.
StimJim provides microsecond temporal resolution with microampere or millivolt scale precision on two electrically isolated output channels. Stimjim will enable new kinds of experiments due to its open-source and scalable nature.
