[visionlist] Suggestions for FMRI Paradigm Display System

[Schwarzbach, Jens Volkmar]

Dear Chandra

At the Center for Mind/Brain Sciences in Trento, Italy, we have implemented the following setup using a Bruker 4T, which has the same physical dimensions as a Siemens TRIO scanner.

Visual stimulation:
LCD projector which projects through a waveguide on a frosted screen at the head end of the bore. The participant looks at the screen by means of a mirror mounted on the headcoil.

The projector is an Epson EMP 7900 (out of production now, but there are alternatives) using a custommade BUHL lens. 

Auditory stimulation: Serene sound by Resonance Technology http://www.mrivideo.com/product/products.asp?id=7&sub_id=14

EyeLink 1000 MR compatible eyetracker http://www.sr-research.com/


Lumina response buttons, but also FORP http://www.curdes.com/index.php/systems.html


Paradigm control:
Matlab with Psychtoolbox 3 http://psychtoolbox.org
and ASF for developing paradigms, scanner synchronization, control of response devices etc, which is described and can be downloaded here:

Let me know if you have specific questions.

Regards,
Jens

>Hello everyone
>
>At NIMHANS in Bangalore, we use a SIEMENS 3 Tesla FMRI along with an
>INVIVO ESYS Paradigm Display System.
>
>We are currently encountering too many problems with the Paradigm
>Display System namely :
>
>1.With the FMC (Fiber Media convertor)  : Resulting in Pixel artifacts
>as well as Bands all over the LCD (Monitor has been changed)
>2. Also the Paradigm Server runs on Windows Vista with errors and bad
>exception handling.
>
>
>Please could anyone of you suggest other paradigm Display Systems and
>Companies, which supports Audio/Video too,  that you have  found
>reliable in performance...(especially if you use a SIEMENS FMRI, but i
>guess most solutions go with any FMRI brand)!
>
>
>Anyway, Ideally, I feel the move must be more towards Open Standards for
>FMRI interfaces (That will allow people to write software which accepts
>an RF Synch Trigger, and  interface a PC audio/display to whatever fiber
>media convertor Fmri display system)
>
>Looking forward to you suggestions.
