Research Overview

The Dong Lab undertakes several projects related to characterizing the neural architecture of mouse models of health and disease and creating open-access data resources and informatics pipelines for mouse brain atlasing. Our Mouse Connectome Project (MCP) ( aims to create a three-dimensional, Google Earth-like, digital Connectome atlas of the C57BL/6J mouse brain. We have well-established state of the art tract-tracing technologies to systematically reveal and map neuronal networks of the whole mouse brain, and have developed a high-throughput pipeline for data production, collection, and analysis. These large-scale, high-resolution, high-quality raw imaging data are made freely accessible to the neuroscience community and general public. To facilitate their use, we have also developed a powerful visualization tool that enables users to visualize and annotate these data.

Recently, we constructed a mouse cortico-striatal projectome: a comprehensive projection map from the entire cortex to the dorsal striatum in the mouse. We use this connectomics approach to characterize circuit-specific cortico-striatal connectopathies in mouse models of disconnection syndromes such as autism spectrum disorder and Huntington disease.
