Event Abstract Back to Event Workflow for integration and analysis of histological data in rodent brain Waxholm Space Eszter A. Papp1, Trygve B. Leergaard1, Gergely Csucs1, Dmitri A. Darine1 and Jan G. Bjaalie1* 1 University of Oslo, Institute of Basic Medical Sciences, Norway Identification and analysis of distribution of various cellular markers visualized in histological materials are fundamental to many experimental investigations in the rodent brain. Since investigations of distributed brain systems and manifestations of ageing and brain disease across the brain often require brain-wide analysis, technologies for efficient acquisition of large amounts of image data from individual brains are increasingly used. A major challenge in this context is the task of analyzing large amounts of high-resolution image data and identifying the anatomical regions and subregions in which the labelled cellular elements are observed. To this end, common reference frameworks are introduced, including brain atlases with standardized brain atlas space, such as the recently introduced volumetric Waxholm Space atlases developed for the mouse and rat brain (Hawrylycz et al., 2011; Papp et al., 2014). We here present a workflow aimed at providing 1) automatic, or semi-automatic identification of labeling in large series of microscopic section images acquired with robotic microscopes or slide scanners, 2) spatial anchoring of histological section images to the volumetric Waxholm Space atlases, and 3) atlas based analysis of the distribution of labelling. The work flow begins with histological section image data and ends with the analysis of data anchored to the Waxholm Space atlases. Automated analyses include image filtering to identify and quantify labelling, and assignment of spatial location parameters to determine where in the brain labelling is located. The workflow was tested using experimental material from recently published studies on brain-wide mapping of axonal connections in the rat and distribution of genetic markers in transgenic mouse models of neurodegenerative disease. High-resolution images of complete coronal, sagittal or horizontal sections were acquired using a slidescanning system. Image processing parameters were optimized on selected representative sections, and then applied to complete image series. Within a wide range of labeling densities, the automatic method provided reliable results and offered opportunities for efficient, standardized analysis of labeling distribution across the brain. The work flow presented, with the concepts and tools provided, allows efficient registration of section image data to a volumetric reference atlas and brain-wide analysis of histologically labelled cellular markers.
