Background:

• Calcium imaging, particularly two-photon microscopy, is crucial for neuroscience research, enabling simultaneous measurement of neuronal and astrocytic activity.
• High-frequency calcium imaging generates large datasets requiring specialized analysis tools, with existing software often lacking capabilities for spectral analysis of high-sampling-rate data.
• Understanding the interplay between neurons and astrocytes at the network level necessitates integrated analysis of cellular activity and electrophysiological data.

Purpose of the Study:

• To introduce the FluoAnalysis MATLAB toolbox, a novel software solution designed for comprehensive analysis of integrated calcium imaging and electrophysiological data.
• To address the limitations of existing software by incorporating advanced features for spectral analysis and cell-type differentiation.
• To facilitate high-throughput analysis of large-scale neural activity data.

Main Methods:

• Development of a MATLAB toolbox (FluoAnalysis) with both graphical user interface (GUI) and command-line functionalities.
• Implementation of algorithms for data loading, region of interest (ROI) identification, and cell classification (neurons vs. astrocytes).
• Integration of spectral analysis techniques for frequency domain analysis of calcium signals and electrophysiological recordings.

Main Results:

• FluoAnalysis enables simultaneous analysis of calcium imaging and electrophysiological data, supporting both manual and automated workflows.
• The toolbox facilitates spectral analysis to identify network-level oscillations and differentiate between neuronal and astrocytic activity.
• It provides a streamlined process for data analysis, from loading to report generation, supporting high-throughput research.

Conclusions:

• The FluoAnalysis MATLAB toolbox offers a robust and versatile platform for integrated analysis of complex neuroscience datasets.
• It enhances the study of brain network dynamics by enabling detailed spectral analysis and cell-type specific activity assessment.
• This tool supports diverse neuroscience research applications, advancing our understanding of neural and astrocytic interactions.
