Stimulus Control Unit
(SCU)

The Stimulus Control Unit (SCU) is equipped with built-in controls and a
display. It provides isolated constant current stimulation and may be connected to
the Acquisition system via a Serial port on the Desktop, Laptop, or Panel PC
computer.
The Stimulus Control Unit (SCU) delivers trains of bi-phasic, constant current
electrical pulses for direct cortical electrical stimulation procedures.
One pair of electrodes are selected to deliver the chosen stimulus.
