FindSim: A Framework for Integrating Neuronal Data and Signaling Models.

Area of Science:

• Neuroscience
• Computational Biology
• Systems Biology

Background:

• Neuronal signaling networks are highly complex, and current experimental methods only capture small, overlapping portions.
• Existing techniques like optical reporters and pharmacological tools have limitations in monitoring and controlling the multiscale processes of neuronal signaling.

Purpose of the Study:

• To develop a framework, FindSim (Framework for Integrating Neuronal Data and SIgnaling Models), for anchoring computational models to structured experimental datasets.
• To systematically refine and validate large, multiscale models of neuronal signaling by integrating diverse experimental data.

Main Methods:

• Developed FindSim, a framework for integrating electrophysiological and biochemical experiments with multiscale models.
• Utilized a structured format to encode experimental conditions, model components, and outcomes.
• Iteratively refined composite cellular models against a database of experiments, ensuring global model validity.

Main Results:

• FindSim enables the integration of numerous individual experiments with large-scale models.
• The framework facilitates systematic model refinement and validation against experimental data.
• Demonstrated a principled and scalable approach to manage model complexity and data diversity.

Conclusions:

• FindSim provides a robust toolchain for improving the accuracy and scope of neuronal signaling models.
• This approach addresses the challenges of complexity and data heterogeneity in computational neuroscience.
• Facilitates iterative model development grounded in experimental evidence for enhanced biological insight.
