Live ECoG capture can be useful for immediate or later analysis of patient ECoGs, for adjusting amplifier
gain settings, and for simulated detection as part of

Important Note: The recording montage must be programmed before live ECoGs can be viewed.
See Create the Recording Montage on page 32.
Note: The maximum length for a live ECoG is four minutes. If the live ECoG is allowed to scroll
for more than four minutes, only the last four minutes are stored.
Note: Live ECoGs are stored on the tablet, not in the neurostimulator memory, and are uploaded
to the PDMS if and when the tablet is logged into the PDMS.
Caution:
Telemetry Artifact
Telemetry may produce an electrographic artifact. If responsive therapy is enabled
with a sensitive detection set, detection of the electrographic artifact may occur,
resulting in therapy delivery. The physician should be aware of possible sensing
artifacts when assessing the ECoG recordings.

Neurostimulator can sense brain activity (ECoGs) from up to four amplifier channels. The
programmed configuration of leads and electrodes you assign to each channel constitute the recording
montage. You create the montage using the tablet
. There can be only one current montage and
