I want to record and analysis ERP in OS X based system.
(with other physiological recording through BIOPAC amplifiers.)
Is there any system can be operated in OS X?
I found EGI ones, but I also heard that's extremely expensive.
Yes, EGI runs with your operating system. But so much of your choice depends on the questions you are trying to answer, and with what type of sample. Both of these are factors that dictate the equipment you need far more than the cost -- you deal with the consequences of your choice every day, whereas the cost is (mostly) a one-time outlay. I would contact EGI, and a whole lot of other companies, and ask ...
Not relevant to the recording side, but EEGLAB (ERP analysis) works on any operating system (it's a toolbox for MATLAB). Point is though, if you want to do the analysis in OS X, you can acquire with any EEG system.
I confirm that EGI runs with OS X. We use it in our lab, however it is a high impedance system and it has its advantages as well as disadvantages. With EGI you can perform analysis in NetStation or export data and analyse it in Matlab too.
I agree with Christopher R Madan. EEGLAB is free and based on Matlab. It's flexible and very efficient if you use codes to run the processes. Their website also provides a lot of information that helps with data analysis. However, I don't know much about the recording systems.
