Main Brain Explorer display mode. Expression of TC1563468 (Etv1, transcription factor variant gene 1) is shown with the quadrats colored by expression level (blue-green is low, yellow is medium, and red is high). The images at the bottom left corner show the original image data from which the data for a quadrat in the subiculum were measured along with some of the surrounding tissue. The detected signal, color mapped by expression level, is shown blended with the original image. The tick marks on the ISH image indicate 100 μm intervals, and the markings on the reference atlas Nissl sections indicate 1 cm.
