Background:

Understanding single neuron morphology is crucial for brain cell-type classification.
Neuron projection trajectories are key to determining connectivity and cell identity.

Purpose of the Study:

To develop an AI method for extracting cell-type-defining features from neuron projections.
To accurately classify neuron projection types and analyze their biological significance.

Main Methods:

Developed a deep sequential model (DSM), an artificial intelligence approach.
Applied DSM to analyze full neuron morphology data and projection trajectories across brain regions.

Main Results:

DSM achieved over 90% accuracy in classifying 12 major neuron projection types.
The model demonstrated robustness against spatial noise, enabling efficient analysis of large datasets.
Successfully applied DSM to discover novel neuron subtypes and analyze co-expressed genes in projection circuits.

Conclusions:

Characteristic long projections defined by DSM can effectively identify neuron cell types.
This AI-driven approach facilitates the management and analysis of complex neural morphology data.
DSM aids in uncovering new biological insights into neuron subtypes and gene expression patterns.
