Whole Mouse Brain Image Reconstruction from Serial Coronal Sections Using FIJI (ImageJ).

Area of Science:

• Neuroscience
• Brain Imaging
• Histology

Background:

• Comprehensive whole-brain analysis is crucial for understanding neural circuits and function.
• Existing methods may have limitations in resolution or the number of markers analyzed simultaneously.
• Mapping neurochemical markers and neuronal projections provides insights into brain organization.

Purpose of the Study:

• To describe a reproducible method for whole-brain reconstruction from mouse brain sections.
• To enable detailed analysis of neurochemical marker distribution and neuronal connectivity.
• To utilize freely available software for accessibility in neuroscience research.

Main Methods:

• Coronal brain sections from mice were processed.
• Up to four fluorescent markers were used for staining.
• Image sets were generated using the FIJI (ImageJ) software for reconstruction.

Main Results:

• A method for producing whole-brain reconstruction image sets was successfully established.
• The technique allows for the visualization and analysis of multiple fluorescent markers.
• The distribution of neurochemical markers and axonal projections can be comprehensively studied.

Conclusions:

• This whole-brain reconstruction method offers a powerful tool for neuroanatomical research.
• The use of FIJI (ImageJ) makes advanced brain mapping accessible to a wider research community.
• This approach facilitates a deeper understanding of brain structure-function relationships in mice.
