Referring to the NIMH MEG Core Facility scanner

When you are writing your paper, you'll want to include a paragraph in your Methods section that goes something like this:

Neuromagnetic data were recorded at 600 Hz with a bandwidth of 0—150 Hz using a CTF 275 MEG system (CTF Systems, Inc., Canada) composed of a whole-head array of 275 radial 1st order gradiometer/SQUID channels housed in a magnetically shielded room (Vacuumschmelze, Germany). Synthetic 3rd gradient balancing was used to remove background noise on-line.

(Substitute the appropriate sampling rate and bandwidth. Usually the bandwidth is 0 to 1/4 the sampling rate.)

If you wish to provide a reference, it is:

Also, if you use the Biowulf to do MEG processing, you should reference them as follows:

This study utilized the high-performance computational capabilities of the Biowulf PC/Linux cluster at the National Institutes of Health, Bethesda, Md.

Please report the publication of articles which made use of the cluster to the Helix Systems Staff, either by citing the reference in email to, or by mailing a copy of the article to:
