AI Revolutionizes Brain Cell Tracking, Paving the Way for Neurological disorder Treatments
A significant breakthrough in understanding brain cell development has emerged from a collaborative effort between the Southwest Research Institute (SwRI) and the University of Texas at San Antonio (UTSA). Researchers developed a novel computational method using artificial intelligence to track the growth and development of neurons over time—a crucial step toward identifying effective treatments for neurological disorders.
The project, funded by a $200,000 grant from the San Antonio Medical Foundation, focused on neurogenesis—the process by which new neurons are formed and integrated into existing neuronal networks. UTSA researchers cultivated human stem cells into complex neuronal networks, mimicking regions of the human brain responsible for regulating sleep, temperature, and mood. These networks were then meticulously observed using confocal microscopy, generating detailed visual data of their dynamic growth.
SwRI scientists leveraged this visual data to train sophisticated algorithms, specifically a U-Net machine learning algorithm, to automatically track individual neurons within the dense, live cultures. This represents a significant advancement over conventional methods that often rely on images of labeled cells in fixed tissue, a process that can obscure the crucial dynamic aspects of cellular behavior. “The research results are a significant step toward automatically classifying the health of growing neuronal networks,” explained dr. Courtney Rouse, the SwRI computer scientist leading the project. The algorithm can definitely help study various neurological diseases and assist in the development and testing of associated therapies,
she added.
The algorithm focused on tracking the soma, the central part of a neuron containing the nucleus, as each neuron possesses only one soma, unlike the variable number of dendrites. By identifying a key point on each soma, the algorithm assigned a tracking number and matched neurons across consecutive images based on proximity. The results were extraordinary: a 93.8 percent precision rate and 99.1 percent recall rate for soma detection. While the detection of dendrites, the smaller, branching structures, yielded slightly lower precision (88.3 percent) and recall (80.9 percent) rates, the overall neuron tracking accuracy reached 85.7 percent.
Dr. Amina Qutub‘s UTSA lab, which developed the experimental models of neuronal development, will utilize SwRI’s cell-tracking methods in a follow-up project to inform AI models for disease screening. Each video of the neuronal network cultures contains timestamped images with hundreds to thousands of neurons per image, providing a rich dataset for AI analysis. This project will help us understand fundamentals of how brain cells develop and communicate,
said Qutub, UTSA professor of biomedical engineering and assistant director of strategic partnerships of the MATRIX AI Consortium. Artificial intelligence methods from this project are also helping us develop a screening tool to accelerate the discovery of biomedicine for brain health and neurological disorders,
she emphasized.
Future research will focus on identifying connections between soma and dendrites, studying neuron responses to environmental stresses like low oxygen or circadian disruption, and correlating neuron electrical activity with tissue health.The potential implications are vast, offering a powerful new tool for understanding the complexities of brain development and neurological disorders.
We are excited that this collaboration is helping close technological gaps in computational neural research. Our algorithm accurately tracked individual soma across timeframes, a fundamental step toward classifying the health of a developing neuronal network.
