Multispectral tracing in densely labeled mouse brain with nTracer

Area of Science:

• Neuroscience
• Bioimaging
• Computational Biology

Background:

• Accurate reconstruction of neuronal morphology is crucial for understanding brain circuitry.
• Existing methods for tracing neurons can be time-consuming and labor-intensive, especially in densely labeled samples.

Purpose of the Study:

• To introduce nTracer, a user-guided, semi-automated ImageJ plugin for tracing multispectral fluorescent tissue samples.
• To provide a tool for rapid and accurate reconstruction of whole cell morphology in large neuronal populations.

Main Methods:

• nTracer is developed as a plugin for the open-source ImageJ software.
• It employs a user-guided, semi-automated approach for tracing fluorescent signals in tissue samples.
• The plugin is designed to handle multispectral imaging data.

Main Results:

• nTracer allows for rapid and accurate tracing of neuronal structures.
• It facilitates the reconstruction of entire cell morphology.
• The plugin is effective in densely labeled brain samples with large neuronal populations.

Conclusions:

• nTracer offers an efficient solution for neuronal tracing and morphological reconstruction.
• The plugin enhances the analysis of complex neural circuits by enabling detailed morphological studies.
• nTracer is a valuable tool for neuroscientists working with high-resolution fluorescent imaging data.
