Hello,

I am kind of new to research in the field of brain computer interface. I don't know if my question is okay to ask here but please I would be really grateful of any help to answer my question. I might have some fund for my research to acquire EEG hardware to use in BCI applications. I still haven't determined which BCI paradigm to use, but most probably a hybrid approach. Also I need the acquired hardware to be suitable for the all the available current paradigms for future work,
My main question is:

What are the most important requirements that I need to check in the EEG amplifier to acquire? What are the questions I need to answer for the specifications in the EEG amplifier? One more question, Does BCI2000 supports the braintronics products?

Thanks,

-- Dina

Dina,

BCI2000 currently does not support Braintronics products. g.tec sells certified amplifier bundles that include BCI2000, which may be of interest.

Thanks Gerv for your reply!

Okay then BCI2000 does not support braintronics now ... but still I would like to know the minimum specs I need to consider in the EEG hardware to acquire.
I noticed this huge price gap between some clinical EEGs to research EEGs . I know that clinical EEG systems are closed systems and I can't interface them directly to the BCI2000, but I was wondering why will it be a problem to use a clinical EEG and then interface with the BCI2000 using file operations?
Also I am designing a new stimulus presentation, so can this be a problem in synchronizing my BCI2000 stimulus presentation software and the clinical EEG hardware? what are other possible problems?
I am asking about the clinical EEG because my budget may not be sufficient for say a g.tec amplifier..

Dina,

Clinical EEG systems usually do not allow for real-time access to the data stream. Thus, they cannot be used for any real-time system, which completely defeats the purpose of using BCI2000, which is made primarily for real-time operation.

The minimum specs completely depend on what you are trying to do. For most application, you would at least need an 8-channel amp.
