A model of cells within the lateral geniculate nucleus (LGN), a structure deep within the brain that relays visual information obtained from the retina onto the visual cortex located near the back of the head. [One of 4 related images. See Next Image.]

More about this Image This still image was derived from animations developed by Greg Hood, John Burkardt and Greg Foss of the Pittsburgh Supercomputing Center. The work contributed to the planetarium show "Gray Matters: The Brain Movie," which debuted in 1999 at the Carnegie Science Center in Pittsburgh. With the brain's neural structure projected on the 3D space of the planetarium dome, "Gray Matters" offers an interactive, multimedia lesson in the science of the brain for children and adults.

"Gray Matters" was a collaboration among the Studio for Creative Inquiry at Carnegie Mellon University, the Center for the Neural Basis of Cognition and the Pittsburgh Supercomputing Center (PSC). The work was supported in part by National Science Foundation (NSF) grant 97-05491.

In 1987, the PSC biomedical program, funded by the National Institutes of Health (NIH), became the first extramural biomedical supercomputing program in the country. Since then, with support from NIH's National Center for Research Resources, PSC has fostered exchange between PSC expertise in computational science and experts in biology and medicine to solve important problems in the life sciences.

With NSF support, PSC provides access to LeMieux, a 3,000 processor terascale system capable of 6 trillion computations per second. As of March 2003, with support from NIH and NSF, PSC has also installed two 16-processor HP GS-1280-based systems. Named "Jonas" and "Rachel" for famous Pittsburgh scientists Jonas Salk and Rachel Carson, these two shared memory systems with very high memory bandwidth will be upgraded to larger systems.

In addition to training and access to computational resources, the biomedical group carries out research in structural biology, protein and nucleic-acid sequence analysis, computational neuroscience and microphysiology. In the latter fields, PSC staff work in developing and conducting research with widely used applications software, including MCell, NEOSIM and PGenesis. (Year of image: 1999)
