The numbers in the electrodes are the recording channel numbers that refer to the channel numbers in the
data acquisition program. Please make sure that you have selected “Configuration” in the “Channel Layout”
under “Data Source Setup” with a total number of 64 channels. In “Amplifier”, please choose FA64I/S and
in “MEA” FlexMEA72. In Layout tab of the display, please click ”Default Map”.
The letter digit code below is the electrode identifier and refers to the position of the electrode in the grid.
Important: The MC_Rack channel map is constructed by looking on the back side of the electrodes,
because the FlexMEA electrodes are placed on the preparation upside down!
Please make sure to connect the left hand side of the FlexMEA72 contact pads (electrode side on top)
via ADPT-FM-72 adapter to the first MPA32I (channels 33 to 64), and the right hand side to the second
MPA32I (channels 1 to 32). Read the SC2x32 data sheet when using a signal collector.
The electrodes are on the same side as the contact pads. The side with the writing “NMI” is the side with
the contact pads and electrodes. It might be a bit confusing that the pads look “stronger” from the wrong
side, but if you hold the FlexMEA72 into the light, you see that the contact pads have a three-dimensional
appearance only from the correct side.
