Background:

Synapses are crucial for neural signal transmission and understanding brain function and disease.
Current synapse quantification tools face challenges due to antibody non-specificity, heterogeneous signal intensity, and low image signal-to-noise ratios.
Accurate synapse quantification is vital for advancing neuroscience research.

Purpose of the Study:

To develop an automated, accurate, and robust tool for synapse quantification from biological images.
To address the limitations of existing methods in detecting and quantifying synapses.

Main Methods:

An automatic probability-principled synapse detection algorithm based on order statistics was developed.
The algorithm was integrated into a synapse quantification tool named SynQuant.
SynQuant is unsupervised, supports 2D and 3D data, and handles multiple staining channels.

Main Results:

SynQuant controls the false discovery rate and enhances synapse detection power.
Extensive experiments demonstrated SynQuant's superior performance compared to existing specialized and generic detection tools.
The tool was validated on synthetic and real biological datasets.

Conclusions:

SynQuant provides an effective solution for accurate synapse quantification, addressing key challenges in neuroimaging.
The developed algorithm and tool facilitate deeper insights into brain functionality and disease mechanisms.
The open-source availability of SynQuant promotes its adoption and advancement in the neuroscience community.
