g-PRIME: A Free, Windows Based Data Acquisition and Event Analysis Software Package for Physiology in Classrooms and...

Area of Science:

• Neuroscience
• Physiology
• Educational Technology

Background:

• Physiology data acquisition and analysis tools are crucial for both research and education.
• Existing tools may be costly or lack integrated analysis and stimulus generation capabilities.
• Development in undergraduate courses can yield valuable, user-driven software solutions.

Purpose of the Study:

• To introduce g-PRIME, a free, versatile software for physiology data acquisition, analysis, and stimulus generation.
• To provide an accessible tool for educational settings and research laboratories.
• To integrate powerful engineering analysis techniques with a biological focus for nervous system studies.

Main Methods:

• g-PRIME is a stand-alone Windows application developed in Matlab, requiring no license for use.
• It supports diverse data acquisition interfaces, from PC sound cards to high-throughput equipment.
• Features include software oscilloscope functions, multi-channel visualization, data logging, real-time/offline filtering, and event detection.

Main Results:

• The software offers extensive analysis options, including signal filtering, multi-parameter event detection, and 2D parameter displays.
• It enables real-time or offline correlation of detected events with other data sources (event-triggered averaging).
• Publication-quality graphics and parameter histograms are supported.

Conclusions:

• g-PRIME effectively merges robust data acquisition and analysis capabilities with a user-friendly interface for physiological studies.
• Its free, accessible nature makes it suitable for both undergraduate education and research environments.
• The software facilitates a deeper understanding of nervous system function by combining engineering and biological approaches.
