5 Programming Stimulus Protocols
5.1 MC_Stimulus II Sample Files for STG 4000 Series
These sample files are intended for demonstrating basic features of the Stimulus Generator
STG 4000 series, for basic applications with the MEA-System. If you are using an MEA-System,
please see also the MC_Rack tutorial in the MC_Rack help or the separate PDF on the installation
volume.
The sample files are automatically installed to the Examples folder in the MC_Stimulus II program
directory.
Please note: The demo files were kindly provided by STG users. MCS does not guarantee that
these files will be appropriate for your application and stimulating electrode type. For using
MEA electrodes as stimulating electrodes, MCS recommends the use of monopolar voltage pulses,
though some MEA users feel that they have better results with bipolar voltage pulses, depending
on the cell culture or tissue used.
Warning: Always obey the recommendations of the stimulating electrode manufacturer.
