Electrodes integrated in the CMOS-MEA are referred in BrainWave as Channels (abbreviated Ch). A

ple channels.
MEA Viewer displays the activity at the current time position by a false-color map. The map gives a
representation of the activity by converting the channels’ voltage values in your MEA to pixel colors. This
is done according to the below color scale and settings. At a specific time location in your recorded Ex -
periment the MEA Viewer gives an image representation of the activity. When instead you visualize live
data acquired from the BioChip or when you playback recorded Experiments, the MEA Viewer refreshes
continuously thus creating an activity movie.
Each square pixel in the MEA Viewer represents a channel in your MEA. Channels are identified by their
row and column coordinates. By convention row coordinate comes first than column coordinate, hence
for instance the channel [10, 5] is the channel at row 10 and column 5.
MEA Viewer allows you to select single or multiple channels. To select multiple channels you can either
hold down Shift on your keyboard while clicking on channels or click and drag an area over the MEA
Viewer.
