NeuroStimDuino: an open source neurostimulator for students, researchers, and enthusiasts interested in neuroscience

Neurostimulation involves the application of short electrical pulses to the surface of the skin to stimulate underlying nerves and muscles. In recent decades, neurostimulation has been used as part of functional electrical stimulation (FES) therapy to help restore movement to muscles in paralyzed limbs in stroke patients and people with spinal cord injuries. While conducting research in areas such as pain relief and sensory feedback, scientists also use neurostimulation to study the effects of electrical current on neurons. Historically, the delivery of neurostimulation has required the purchase of expensive research-grade equipment or costly, time-consuming custom hardware constructs. NeuroStimDuino provides an open source alternative in the form of an Arduino shield.
