# TRIUX neo MEG system Upgrade

> **NIH NIH S10** · MASSACHUSETTS GENERAL HOSPITAL · 2021 · $2,000,000

## Abstract

Project Summary / Abstract
This application seeks support from the ORIP High-End Instrumentation (HEI) Grant program to fund a MEGIN
Triux Neo MEG system to be used for basic/clinical/translational research at the Athinoula A. Martinos Center
for Biomedical Imaging. This system will replace our existing, 20-year-old Vectorview system, and will provide
an substantial increase of performance for the wide range of research at the Martinos Center: psychiatric and
basic neuroscience studies, clinical research on neurological and psychiatric diseases, clinical studies of epilep-
tic patients, and development of novel instrumentation and analytical tools. While the Magnetoencephalography
(MEG) research program at the Martinos Center has been very successful, our MEG system, installed in 2001,
has come to the end of its life cycle. Service is guaranteed by the manufacturer only for another year: there is a
definite need to upgrade the existing system. The proposed upgrade will not merely replace our existing MEG
system but will offer new features for improved performance and data quality: (i) The instrumental noise level of
the new “ARMOR” sensors is lower, which will benefit studies of deep brain structures and the cerebellum as
well as studies of spontaneous brain activity in general. (ii) The sensors in the new system are very stable and
robust, which guarantees uniform high data quality in long recordings in, e.g., sleep studies and in complex
cognitive experiments. (iii) The new system is equipped with new EEG hardware, which facilitates high-quality
recording of combined MEG/EEG data. (iv) The new system can be operated in supine, upright, and reclined
positions, which provides more options for experimental design and subject/patient comfort. (v) The system is
equipped with a closed-circuit helium reliquefication system, which reduces downtime, saves limited helium re-
sources, and reduces operational costs. In addition, MEGIN is about to introduce new acquisition software, which
makes the system more user friendly and is geared towards clinical and translational studies. The system will
be an up-to-date testbed and comparison platform for the unique instrumentation and software development
work at the Martinos Center, including real-time processing of MEG/EEG data, creation of new tools for detecting
and analyzing signals from brain structures outside the neocortex, and development of new devices and sys-
tems, which will use new sensors enabling on-scalp MEG measurements to complement the proven capabilities
of the robust SQUID-based technology. The results of this development work will be freely disseminated to the
MEG/EEG communities at large. By serving a highly productive interdisciplinary group of PHS-funded investiga-
tors, this proposed upgrade will enhance existing research programs while at the same time fostering opportu-
nities for new projects and collaborations to emerge and flourish. This upgrade will thus help pave the way for
othe...
