What the scientists told Allen was that they really wanted a virtual map for the genes that turn on and off in the brain, akin to the blueprint of the entire human genome that, at that time, was nearing completion. So in 2003, the same year that the Human Genome...
The project, which was completed Tuesday, details the activity, or expression pattern, of genes. It includes vivid three-dimensional images and descriptions of 20,000 genes and their activity, and has already become a go-to source for researchers studying everything from multiple sclerosis to brain tumors. Researchers can log...
For Dr. 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...
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...
The Atlas is just the start of what neuroscientists see as the future of brain science. Already, the mouse atlas has revealed something new about brain neurons - researchers had always thought that brain neurons were pretty much the same, and were distinguished mainly by how they were hooked up to...
