Scientists at the Allen Institute for Brain Science in Seattle, USA, have recently completed the Allen Brain Atlas, a threedimensional map detailing the expression of over 21,000 genes throughout the mouse brain. This comprehensive, three-year study depended on five Tecan GenePaint™ systems for the automated in situ hybridization of gene probes in hundreds of thousands of brain sections, providing patterns of expression for every gene down to the cellular level. The atlas is freely available at www.brain-map.org.
