This paper develops a scalable PS-OCT system for whole-brain imaging in rhesus macaques, achieving high-resolution volumetric data with multi-terabyte datasets.

The paper characterizes the 3D organization of large axons in human white matter, revealing distinct architectural patterns across different brain regions.

The paper introduces ExA-SPIM, a microscope that enables high-resolution imaging of large tissue samples without sectioning, demonstrating its use on mouse brains and human white matter.

The paper introduces a computational pipeline for automated tracing and assembly of axons across serial sections, validated on centimeter-scale data for orientation analysis and proofreading.

The paper identifies two rod bipolar cell types in zebrafish that are related to mammalian rod bipolar cells, suggesting the primary rod pathway evolved over 400 million years ago.

The paper visualizes dense distributions of immunolabeled proteins in adult macaque visual cortex using expansion microscopy and light sheet imaging, enabling multimodal atlas creation.
