Expressing what's on your mind: DNA arrays and the brain

Article metrics


Questions about brain function and disease are being addressed with parallel genomic approaches. High-density DNA arrays make it possible to monitor the expression levels of thousands of genes at a time, and are being used to address old questions in new ways and to generate new hypotheses about the workings of the brain.
