...Greg Foltz, a neurosurgeon at the Seattle Neuroscience Institute at Swedish Medical Center who studies incurable brain tumors, the mouse atlas functions as a springboard for better understanding how these difficult tumors develop and grow. "We need clues," he says. "When a patient comes in and has a tumor removed, we take that tumor and complete a genomic study, but all we have is a database of genes. The best analogy I can come up with is that this genomic data is like having just the names in a phone book; it's only a list. We want to know...
...Foltz is also part of the Allen Brain Atlas' next project, which involves mapping the human cortex. The cortex is where sensory information from the eyes, ears, nose and touch neurons is processed. He and his group are providing samples of human brain tissue, including archived material from patients who have suffered from diseases such as epilepsy, to give researchers a better understanding of which genes are involved in disease states...
...like other cells in the body, show a diverse array of gene expression patterns, meaning that different cells use different genes at different times to perform their complex functions. "Under the microscope, neurons look the same, but in terms of gene expression, it looks like there are differences," says Foltz. "This has opened up whole new fields for cognitive neuroscientists to understand what makes the [neurons] that go to the eye different from the ones that go to the memory center or the ear. The atlas allows you to make inferences, and inspires you to think of all kinds...

...essay grader can't not judge style or originality--the program works best with focused, fact-or content-based essay topics in disciplines like history, science and economics, Foltz said. In fact, highly original essays are rejected by the computer as irregular and must be graded by hand...
