A compact wireless multi-channel system for real-time intracortical microstimulation of behaving rodents

In this paper we present a compact wireless 8-channels stimulating system specifically designed to deliver patterns of electrical stimuli into the cortex of freely behaving small laboratory animals. The stimuli are designed as trains of bi-phasic current pulses with programmable duration, frequency and amplitude using a LabVIEW based graphical user interface. The reduced weight of the stimulation control unit and the possibility to directly connect it to a behavioral box, makes the system suitable to be worn by rodents while performing behavioral experiments.
