Room 94T is equipped with 1 workbench, 1 inhalation anesthesia system capable of using Halothane or Isoflurane, floor standing Zeiss operating microscope, temperature controlled water blanket. Room 1067 is dedicated to large animal surgery and prep and is equipped with 1 workbench, an  operating table, an inhalation anesthesia system capable of using Halothane or Isoflurane and a temperature controlled water blanket.
 
 
 
'''Behavioral Testing Laboratory'''
 
 
 
The behavioral testing suite, located on the second floor of Building 149, provides a quiet and controlled environment for neuropsychological testing, developing and piloting behavioral paradigms, and running pre- and post-scan experiments with children and adults. It consists of two testing rooms with one-way mirrors (rooms 2236, 2234), separated by a control room (room 2235), which may also serve as an observation station or additional testing space. Each of these rooms is equipped with a PC, a MAC and a button-press response box (with millisecond accuracy), identical to those used in the MR research bays thereby allowing for portability of the paradigms developed in the behavioral setting. Auditory stimuli may be presented via speakers in sound-field or over headphones. A digital audio tape recorder, a microphone, a touch-screen monitor, a video projector and a projection screen will also be available for stimulus presentation and/or recording subject responses. Transfer of experimental paradigms and data backup may be accomplished with removable media.
 
 
 
'''Mock Magnet'''
 
 
 
The purpose of the mock magnet is to acclimate normal and clinical populations (children and adults) to the MRI environment in preparation for participation in MRI studies. The mock scanner is modeled after the Siemens 3T Allegra system in structure and dimensions. Its parts include an original Siemens patient table, funnel and head coil. Transducers and recordings of the scanner noise from the Siemens 1.5T (Sonata) and 3T are used to simulate the vibrations and pulse sequence noises associated with scanning. Stimuli will be presented using headphones or a rear projection system, with the mirror mounted on the head coil (as found in Bays 2, 3 and 4), along with a button box for responding. Potential subjects who are anxious about participating in MRI studies are gradually desensitized to the confined space of an MRI magnet tunnel through a series of training steps. A feedback system to help train subjects to stay still when in the scanner is being developed. The mock scanner is located near the Behavioral Testing Suite and in close proximity to the GCRC Biomedical Imaging Core Facility and the 1.5T and 3T magnets.
 
 
 
'''Biomaterials Laboratory''' 
 
 
 
This laboratory, physically integrated within the High Field Spectroscopy room, contains a Carver (Wabash, IN) 25 ton microprocessor controlled hydraulic press, a Spex Industries (Edison, NJ) cryogenic grinder, and a computer controlled Lindberg/Blue M (Watertown, WI) 1200 °C 3 inch tube furnace, which are used for preparation and analysis of biomaterial specimens and implants.  A special MRI-compatible furnace, capable of 950 °C operation within the 4.7 T magnet, equipped with a quadrature birdcage RF coil, was engineered and fabricated in the Biomaterials Laboratory for in situ studies of high temperature materials processing.
 
 
 
'''Martinos Center Histological Analysis Lab'''
 
 
 
The laboratory is  equipped with a  Canon digital camera, camera stand and tripod for photographing of  blockface images prior to sectioning. For tissue sectioning, we use a Leica  2000R microtome for  cutting frozen sections.

'''Computer Facilities''' 
 
 
 
The Center’s IT infrastructure consists of over 200 Linux workstations and 150 Windows and Macintosh desktops on users desks owned by individual research groups. There are also a few Sun, SGI and HP workstations used at the center. There is a server farm of over 25 Linux servers handling central storage, email, web and other services. Overall storage capacity of the center exceeds 100 terabytes. There is also a 290 node computing cluster for batch analysis. 124 of the nodes are Dual Opterons (64 bit) and 18 of these nodes have 16 MB of RAM. The total CPU count is 450. The IT facilities are supported by a small IT staff of two full time PhD level network administrators and several additional full time professionals, including three full time programmers supporting in-house-developed software tools. Available commercial software includes AVS (Advanced Visual Systems, Waltham, MA), IDL (Research Systems), Mathematica (Wolfram Research, Champaign, IL), MATLAB (The MathWorks, Natick, MA) and MEDx (Sensor Systems, Sterling, VA) for general-purpose computation, simulation and image analysis; and XWIN-NMR (Bruker BioSpin), Origin (OriginLab Corp., Northampton, MA), Nuts (Acorn NMR, Livermore, CA) for analysis of NMR spectra and the Siemens IDEA development environment for pulse sequences and image reconstruction software (Siemens, Erlangen, Germany). A substantial level of internal software development for image and data analysis is ongoing, using HTML, C, C++, Java, FORTRAN, Pascal, Perl and TCL/TK.
 
 
 
'''Education Area''' 
 
 
 
This area contains a conference room, audio visual laboratory (equipped with computers, TV monitors, VCRs, carousels, teaching files and tapes), staff offices and general desk space for graduate students, postdoctoral fellows and junior faculty.
 
 
 
'''Administration Area''' 
 
The Center’s administration area is located on the second floor of Building 149 in area 2301. Facilities located here include fax machine, Xerox, standard and color laser printers, and faculty and staff mailboxes. This area contains faculty and secretarial office space and a conference room.
 
 
 
=== Description of the GCRC Biomedical Imaging Core Facility ===
 
 
 
The Biomedical Imaging Core is located on the 2nd floor of building 149 of the MGH Charlestown Navy Yard in approximately 1,500 sq.ft and is situated directly above the dedicated research MR scanners and close to the MEG/EEG imaging site. The space contains a patient reception/waiting area, 2 outpatient exam rooms, computing resources, laboratory/storage space and office space for the staff.
 
 
 
'''Patient reception/waiting area'''
 
Subject scheduling for use of the outpatient exam rooms, mock scanner and nursing support is done through the main GCRC. Research subjects use this waiting area whether they are scheduled for a visit to one of the exam rooms or one of the imaging facilities.
 
 
 
'''Outpatient Exam Rooms'''
 
The outpatient exam rooms support all clinical imaging studies that include complex cognitive, pharmacological and physiological challenges and monitoring both before and during imaging.  Physical examinations, cognitive testing, insertion of intravenous lines, and other patient centered activities are carried out in the exam rooms.  There are four semi-private (curtains can separate the patient recliners) exam areas in one large room and two private rooms with stimulus presentation capabilities that replicate what is in the imaging environment.  The private exam rooms are sound-attenuated and equipped for performing physical exams.  One of the private rooms is shielded and thus appropriate for conducting electrical and optical imaging studies.
 
 
 
The electrically shielded exam room is equipped for physiological monitoring, blood sampling, and drug infusions. The physiological monitoring modular system purchased for the exam room duplicates the system that is currently set up in the 1.5 T MRI suite. In the next year similar systems will be installed in the 3 T system in Bay 4 and for the MEG/EEG suite. The modular physiological monitoring system includes equipment to measure invasive and non-invasive blood pressure, heart rate, EKG, oxygen saturation, temperature, skin conductance, expired oxygen and carbon dioxide concentrations and respiration rate.  The outpatient exam room and Bay 4 MR suite are also equipped with medical grade air, O2 and CO2.
 
 
'''Clinical Laboratory/ Pharmacy Locker'''
 
The Core facility includes a small clinical laboratory for specimen preparation and temporary storage of specimens with centrifuges and 4o and –20 o C refrigerator/freezer space. Biomedical Imaging Core maintains code carts equipped with pediatric supplies adjacent to the GCRC dedicated space as well as at appropriate sites near each of the imaging systems that are supporting invasive studies.  The Bioimaging Core also maintains a medication closet for investigators to store a supply of investigational drugs that can be dispensed on site. MGH Research Pharmacy provides logistical support for pharmacy services such as special formulations, drug procurement, storage, record keeping, study fees, inventory control, drug distribution, packaging and labeling, randomization and blinding.  This ensures that clinical trials that have biomedical imaging as outcome measures are in compliance with federal regulations.  The laboratory is outfitted with both clean and dirty areas for storage with separate wash facilities.
 
 
 
'''Offices'''
 
There are two offices that are shared by the GCRC Core staff, biostatistician, the software developers, and research nurses.  Each office is equipped with a networked workstation.  These offices are used for consultations with investigators.
