MEA Window
The window on the right side is divided into four separate window panes and has five tabs:
"Field Potential", "ROI Selection", "Heartbeat", "HB Averager" and "QT-related Analysis".
The setting of the tabs influences each of the separate windows in the tab.
Select "Field Potential" tab. Please see the upper picture.
The single channel view on top of the right window panes shows field potentials: Recorded
data traces are displayed in the MEA electrodes pane.
If you select one or more than one MEA electrodes in this window pane by clicking on the desired
channel, they are displayed in the overlay plot window below.
The color map displays the spreading of the excitation of a heartbeat from the pacemaker (or
the earliest time point detected if the pacemaker is not on the MEA) to the outer regions of the
cardiac cell culture or tissue. The isochrones are indicated by black lines. The colors indicates the
time distance between the first signal and outer regions of excitation. Red color represents the
pacemaker when using the color map "jet inverse". Below the map the actual timestamp is
displayed. The color map corresponds with the single channel view, and with the field potential
windows.
