Lab Resources



The Solodkin/Small Laboratory contains a signficant array of computational and physiological measurement tools for performing fundamental and translational research with human subjects. In addition to a handful of PCs, mainly used for statistical analysis and presentation creation, the lab has over 20 Linux and Mac workstations, organized in a local high speed network, and used for individudal computing and local cluster computing. The Linux boxes are all running Red Hat Enterprise and the Macs run OS X Leopard (10.5). Using these machines, researchers at HNL have access to the central storage system, located locally. The central storage system can hold up to five terabytes of data, and is accessible from all the machines in the lab. The individual Macintosh and Linux workstations vary from low end machines used mostly for viewing final datasets, to multi-processor, multi-gigabyte RAM machines that can handle large amounts of data processing.

In addition to significant in-house data processing, researchers at the Brain Circuits Laboratory collaborate closely with the Computation Institute of The University of Chicago, and make significant use of various cluster computer arrays and international grid resources, including Open Science Grid and Teragrid. These multi-node grid systems allow researchers at the Human Neuroscience Laboratory to perform highly advanced distributed computation, which has become an important part of our methodological research effort.

As well as an array of computers, both local and remote, used for data processing and storage, the Brain Circuits Laboratory has computers that are used to present stimuli to partients during physiological research. There are two stimulus computers in the scanning suite, including both Windows (E Prime, Presentation, Inquisit) and Mac (Psyscope) platforms.

The UCI Research Imaging Center contains a home-built 4 Tesla MRI scanner and a commercial Philips 3 Tesla scanner. This scanner is equiped with multiple video and auditory presentation systems, an eye tracing system, and numerous response boxes. The imaging center is a short distance from the Clinical Core of the Brain Circuits Laboratory.

The Solodkin/Small Laboratory itself contains a 128 channel Electrical Geodesics system for electroencephalographic recording along with sensor nets of various sizes. Both potassium chloride saline and hydrogel nets are available, for both ERP experiments and longer high-density sleep recordings.

The Laboratory also contains a MagStim dual pulse system for transcranial magnetic stimulation, along with a BrainSight frameless stereotaxy system for image-guided stimulation.
