The Dartmouth Brain Imaging Center
History of the Center
In November of 1999, Dartmouth College became the first liberal arts school in the country to own and operate an MRI machine for strictly research purposes. Since then, Dartmouth faculty, graduate students, and undergraduate students have all used the Dartmouth Brain Imaging Center (DBIC) magnet to research everything from free will and morality (Wheatley Lab) to how amygdala dysfunction can lead to anxiety disorders (Whalen Lab), and many, many subjects in between. Non-Dartmouth investigators may also use the center provided they do so under a collaborative agreement with a Dartmouth faculty member.
The DBIC first opened under the direction of Scott Grafton with a 1.5 T GE MRI machine. The center is supported by Dartmouth College and The College of Arts and Sciences and is located in beautiful Moore Hall. Since its opening, DBIC has upgraded to a state-of-the-art 3.0 T Philips MRI machine and Scott Grafton and former Dartmouth Cognitive Neurosciences Director Michael Gazzaniga have moved onto warmer climates at UCSB. Professor George Wolford served as the interim director until the current director, Jim Haxby, arrived in January, 2008.
Dartmouth College is extremely fortunate to have a brain imaging center completely dedicated to research. This focus creates opportunities for undergraduate, graduate, and faculty research available at few (if any) other institutions. Almost half of the undergraduate honor's theses in the last 3-4 years have used the magnet. Most studies are conducted on healthy subjects, although some have been conducted on patient populations. Students are often recruited as volunteers and given a small stipend or "T-points" (which count towards extra credit in some psychology classes) for their participation.
In the past eight years, researchers have performed thousands of scans. Pigs, monkeys, and even a bear head have been scanned for anatomic research, and some generous volunteers have been scanned upwards of 100 times.
