A decision is a deliberative process that results in the commitment to a categorical proposition. An apt analogy is a judge or jury that must take time to weigh evidence for alternative interpretations and/or possible ramifications before settling on a verdict. Here we evaluate progress in understanding how this process is implemented in the brain. Our scope is somewhat narrow: We consider primarily studies that relate behavior on simple sensory-motor tasks to activity measured in the brain because of the ability to precisely control sensory input, quantify motor output, and target relevant brain regions for measurement and analysis. Nevertheless, our intent is broad: We hope to identify principles that seem likely to contribute to the kinds of flexible and nuanced decisions that are a hallmark of higher cognition.

What is the Grid? How are Grids built and used (today)? What Grid software is available and what does it do? BREAK (somewhere during part III) How have others succeeded? History For years, a few whacky computer scientists have been trying to help other scientists use distributed computing. Interactive simulation (climate modeling) Very large scale simulation and analysis (galaxy formation, gravity waves, battlefield simulation) Engineering (parameter studies, linked component models) Experimental data analysis (high-energy physics) Image and sensor analysis (astronomy, climate study, ecology) Online instrumentation (microscopes, x-ray devices, etc.)
