After changing detection settings, the
N
EUROSTIM
S
ETTINGS
screen has a
R
EVERT
button next
to the
S
AVE
button. Select
R
EVERT
if you want to remove all changes to the detection settings
and revert to the current detection set.

Note: Detection tools and detectors support you as you exercise clinical judgment to define
detection settings. Detectors and settings initially suggested by the software (as described in
Phase 2 on page 48) offer a starting point only. The software does not preempt nor replace your
clinical judgment.
In previous versions of programmer software, the physician selected a set of ECoGs with specific patterns
to be detected, chose a detection tool and settings, observed the simulated detections that would occur
on that set of ECoGs, and then repeated the process iteratively to define a detection set.
In the current version, when you use the SimpleStart Feature to select a waveform pattern to detect, the
software suggests a detector (one of
P
OWER
C
HANGE
,
R
HYTHMIC
A
CTIVITY
or
S
PIKE
A
CTIVITY
)
and
associated settings as a proposed fit for that pattern. You use this procedure initially (in
) to create a new detection set when you have first gathered
ECoGs containing the type of activity you wish to detect. This detection set is a suggested starting point
to assist you as you exercise clinical judgment to define detection settings. It suggests a starting point
only. It does not preempt nor replace your clinical judgment. The software also simulates the suggested
detector and settings on all of the patient’s stored ECoGs. By reviewing the simulated detection on an
ensemble of stored ECoGs, you can confirm that detection occurs when desired, or change the selected
pattern, detectors and/or settings to make detection occur when desired. Having defined up to four
detection patterns and associated settings, you then save them as a detection set. (Up to four detection
patterns on up to two channels comprise a detection set.)
Detection Tools and Detectors
The RNS
®
Tablet uses three kinds of detection tools:
P
OWER
C
HANGE
(page
),
B
ANDPASS
(page
), and
A
REA
(page
).
•
The
P
OWER
C
HANGE
detection tool (formerly line length) is used in the
P
OWER
C
HANGE
detector.
•
The
B
ANDPASS
detection tool is used in two detectors,
R
HYTHMIC
A
CTIVITY
and
S
PIKE
A
CTIVITY
.
•
The
A
REA
detection tool is infrequently used and can be selected only manually from the
D
EFINE
P
ATTERNS
dialog (select
M
ORE
C
ONTROLS
>
A
DV
C
ONTROLS
).
Note: R
HYTHMIC
A
CTIVITY
and S
PIKE
A
CTIVITY
both are types of ECoG activity that can be
detected by the B
ANDPASS
tool. The A
REA
tool is not used to generate a suggested detector from
an ROI, but can be manually programmed by selecting M
ORE
C
ONTROLS
>
A
DV
C
ONTROLS
.
