What is it indicated for?

The Digital NeuroPort Biopotential Signal Processing System supports recording, processing, and display of biopotential signals from user-supplied electrodes. Biopotential signals include: Electrocorticography (ECoG), electroencephalography (EEG), electromyography (EMG), electrocardiography (ECG), electrooculography (EOG), and Evoked Potential (EP).

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
