- Signal Processing
Background:
- Electroencephalography (EEG) is crucial for analyzing brain activity.
- Visualizing EEG data, especially for paroxysmal discharges, presents analytical challenges.
- Current methods may lack comprehensive spatial and temporal representation.
Purpose of the Study:
- To develop an advanced system for analyzing 16-channel EEG data.
- To generate 3-dimensional sequential topographical displays of EEG field potentials.
- To improve the analysis of propagation and field distribution of paroxysmal discharges.
Main Methods:
- Utilized 16-channel EEG recordings.
- Developed a system for generating 3D sequential topographical displays.
- Focused on creating a user-friendly interface for data storage and analysis.
Main Results:
- Successfully generated 3D sequential topographical displays from EEG data.
- Demonstrated the system's capability to visualize propagation and field distribution of paroxysmal discharges.
- Ensured ease and flexibility in data storage and analysis.
Conclusions:
- The developed system offers a comprehensible method for representing EEG field potentials.
- This visualization tool facilitates a deeper analysis of neurological event dynamics.
