functional near-infrared spectroscopy

Anybody used or thought about using an fNIRS signal in BCI2000?

Krysta,

I am not aware that anybody used fNIR in BCI2000. However, it would be rather simple to use it, e.g., in conjunction with the CursorTask. Do you have a device you would like to interface with BCI2000?

Yes, we use ISS' oxiplex system to acquire fNIRS data; it would be superneato if it could be recorded through bci2000 instead of having to route it through ISS' acquisition software.

Krysta,

In order to do this, two things have to be met:
1) the fNIR software has to be able to stream out the data in real time, or there has to be a possibility to acquire data from the device in real time (using a SDK, dll, etc.)
2) You have to have somebody with C++ programming experience.

If both items are met, we will be glad to help you with this and point you in the right direction.

fNIRS

Post by audrey » 01 Jul 2009, 09:31

Hi Gerv,

I'm working with Krysta on using BCI2000 with fNIRS. Our device is able to stream data in real time, and we have plenty of people with C++ programming experience.

I have started exploring the documentation and briefly looked at the code. I know we need to write a ADC module for our device, and it's been recommended to use another one as a starting point, but I am not familiar with any of the EEG devices. Any recommendation?

Also, I would greatly appreciate any advice on how to start, as you offered in your post.

Hi,

I would start by checking out the tutorial on writing a new data acquisition module:

http://www.bci2000.org/wiki/index.php/P ... ion_Module

I would begin by modifying an existing module, e.g., the SignalGenerator module and use the information in the tutorial as a guide/tutorial.

Let me know how this goes. This is exciting.

Gerv
