Abstract

The reconstruction of 3D microscope images is vital to understand the 3D morphology of neurons and glial cells, a critical step in brain anatomy and function research. Manual and digital neural tracing has been used for investigating neurodegeneration, modulating animal behavior, and mapping out complex neural circuits. We propose a deep learning model and methods that can be further refined relative to the biological question at hand, for the analysis of morphologies, tracing, and reconstruction of neurons and glial cells. The model we propose will utilize a convolutional neural network with transformers to trace 3D images, which will then be used to extract relevant features from the images to classify different types of neurons as well as different sub-compartments of neuron and glial cells. Using datasets of annotated neuron images, Zhou and colleagues achieved average accuracy of 98% with their open software tool-box, DeepNeuron, whereas the current leading model, authored by Li and Shen only has an average accuracy of 96%. As we aim to standardize across pooled datasets and correct annotations, our model has the potential to significantly improve the efficiency and accuracy of neural classification and offer deeper insights into neural connectivity and neurodegeneration.
