Background:

Whole-brain analysis of single-neuron morphology is essential for understanding brain complexity.
Reconstructing neurons from large-scale microscopy data (terabytes to petabytes) presents significant computational challenges.

Purpose of the Study:

To develop an efficient and scalable solution for large-scale single-neuron reconstruction.
To streamline the process of analyzing complex neural projectomes from mammalian brains.

Main Methods:

Developed 'Gapr' (Gapr accelerates projectome reconstruction) software.
Integrated deep learning-based automatic reconstruction and automatic proofreading.
Implemented high-throughput collaborative proofreading via crowd users and a seamless user interface.

Main Results:

Successfully reconstructed over 4,000 neurons in mouse brains.
Demonstrated significant reduction in human workload for proofreading.
Revealed morphological diversity in cortical interneurons and hypothalamic neurons.

Conclusions:

Gapr provides an effective solution for large-scale single-neuron reconstruction projects.
The developed platform facilitates efficient analysis of complex brain structures.
Enables deeper insights into neuronal morphology and brain organization.
