What This Document Is
This is a detailed assignment for an upper-level Bioelectricity course (BME 307) at the University of Rhode Island, centered around computational modeling of cardiac physiology. Specifically, it tasks students with simulating and analyzing the action potential of the sinoatrial (SA) node – the heart’s natural pacemaker. The assignment builds upon prior coursework involving the Hodgkin-Huxley model and requires applying those principles to a more complex biological system. It culminates in a formal report detailing the methodology, results, and implications of the simulation.
Why This Document Matters
This assignment is crucial for students seeking a deeper understanding of cardiac electrophysiology and the mathematical modeling of biological systems. It’s particularly valuable for biomedical engineering students, those interested in computational physiology, or anyone preparing for advanced studies in cardiology or related fields. Successfully completing this assignment demonstrates proficiency in applying established biophysical models to a clinically relevant problem and communicating complex scientific findings in a clear, concise manner. It’s best utilized *during* the course when actively working on the simulation project, and as a reference when preparing the final report.
Common Limitations or Challenges
This document outlines the assignment requirements and provides context for the SA node model, but it does *not* provide pre-solved code, step-by-step instructions for the simulation, or a complete analysis of the results. Students are expected to leverage their existing knowledge of the Hodgkin-Huxley model and independently develop and refine the necessary MATLAB scripts. It also assumes familiarity with numerical methods for solving differential equations. The document references an external research paper ([1]) which is not included.
