Using the Define Patterns Dialog
Note: A pattern defines the type of ECoG activity to be detected.
6. In the D
EFINE
Touch on the point of the ECoG where you would like detection to occur. Starting from the
point where you touch, a 3-second window of time (or region of interest, ROI) is bracketed on
the ECoG. This touch feature to bracket a 3-second region of interest is called the SimpleStart
Feature.

•
The 3-second window bracketed on the ECoG is the pattern you are identifying for
detection; it should contain the type of pattern you would like to detect.
•
Each 3-second window is identified as one of the four possible patterns you can define,
A1, A2, B1 or B2. (The 1 and 2 indicate the first and second ROI you select. Typically the
A and B patterns are defined on different leads.)
•
You can touch on the window identifier (A1, A2, B1 or B2) and slide the window left or
right to place it where it gives the desired simulated detection results. Note that the
software may apply a different suggested detection tool when you move the window.
Note: You cannot select a 3-second window within the first 5 seconds of an ECOG, because the
software looks for differences in the ECOG data before the 3-second window and needs sufficient
preceding data to determine this difference. If you touch before 5 seconds in the ECoG, the
software places the window starting at the 5-second mark.
