## Indications for use
The Cervello® STIM cortical stimulator is a low power, constant current, bi-phasic stimulator intended for cortical stimulation during electroencephalography examinations (i.e. stereoEEG). The stimulation is applied to the brain using third-party stimulation probes (including cortical or intracranial electrodes) and the resulting cortical or deep brain potentials themselves are recorded using third-party cortical or intracranial electrodes. The Cervello® STIM itself is an accessory to the Cervello® Basic Biopotential Signal Acquisition System. The stimulation parameters, the electrodes selection and the activation of the stimulation current are all set-up and controlled from it. The Cervello® STIM can operate only when so connected and with the Cervello software; it cannot serve as a stand-alone cortical stimulator.
