Near-Freezing-Temperature Golgi Neuronal Staining for X-ray Imaging of Human Brain.

ABSTRACT: Achieving detailed neuronal structural information in large-volume brain tissue has been a longstanding challenge in human brain imaging. A key obstacle arises from the trade-off between staining efficiency and tissue autolysis. Traditional Golgi staining, typically conducted at room temperature or 37 °C to optimize staining efficiency, leads to rapid autolysis of brain tissue, resulting in the loss of fine structural details. Here, a near-freezing temperature (NFT) staining strategy in post-mortem frozen (PMF) human brain samples are presented, using a mercury chloride-based method under ice-water bath conditions. In contrast to the 37 °C Golgi staining, this NFT-based method significantly reduces tissue autolysis, preserving fine neuronal structures. Notably, neuronal counts in the same
