SiMEA: a framework for simulating neurons on multi-electrode array.

Area of Science:

• Neuroscience
• Bioengineering
• Computational Biology

Background:

• Multi-Electrode Arrays (MEAs) are crucial for in-vitro neuronal recordings.
• In-vitro cultures are susceptible to errors, leading to failed experiments and increased costs.
• Accurate spatial positioning and cell health are critical for reliable MEA data.

Purpose of the Study:

• To develop and implement a simulation framework for neuronal cultures on MEAs.
• To provide researchers with a virtual sandbox for experimental design.
• To minimize risks and optimize resource allocation in MEA-based research.

Main Methods:

• Developed a computational framework for simulating spatial positioning of neuronal cultures on MEAs.
• Integrated cell density, cell death over time, and diverse cell morphologies into the simulation.
• Utilized the Brian2 simulator for modeling neuronal spiking activity and interactions.

Main Results:

• The framework allows for realistic simulation of neuronal culture parameters.
• Researchers can test different experimental setups virtually before in-vitro implementation.
• Identified potential issues and optimized parameters for improved experimental success rates.

Conclusions:

• The proposed simulation framework enhances the reliability of in-vitro MEA experiments.
• It serves as a valuable tool for optimizing experimental design and reducing failure rates.
• Facilitates cost-effective and efficient research in neurophysiology.
