## Indications for use
The SD LTM STIM 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 SD LTM STIM itself is an accessory to the SD LTM 64 EXPRESS Signal Acquisition System and SystemPlus EVOLUTION software. The stimulation parameters, the electrodes selection and the activation of the stimulation current are all set-up and controlled from these devices. The SD LTM STIM can operate only when so connected and with the SystemPlus EVOLUTION software; it cannot serve as a stand-alone cortical stimulator.
