研究目的
To develop a method for inferring the depth of neurons in bright-field microscopic images of histological sections of a human brain, enabling accurate 3D localization of neurons.
研究成果
The method successfully infers a third spatial dimension for 2D neuron locations in bright-field images, enabling more realistic 3D localization of neurons within histological slides. This approach enhances the analysis of cellular organization and tissue cytoarchitectonics.
研究不足
The method relies on the quality of the histological staining and the resolution of the scanning equipment. The presence of background signal from out-of-focus structures may affect accuracy.
1：Experimental Design and Method Selection:
The study uses multi-level scanning of bright-field images along the z-axis to determine neuron locations in three dimensions.
2：Sample Selection and Data Sources:
Histological sections of an adult human brain stained using NeuN were used.
3：List of Experimental Equipment and Materials:
Hamamatsu Nanozoomer
4：0 scanner, NDPITools software. Experimental Procedures and Operational Workflow:
Images were acquired at multiple optical planes, processed to segment neuron bodies, and tracked across the image stack to measure sharpness.
5：Data Analysis Methods:
Variance of Laplacian metric was used to measure neuron sharpness, with cubic spline interpolation for continuous z-coordinate values.
