A new PC program analyzes electroencephalogram (EEG) data using brain electrical activity mapping. This tool aids in clinical studies for neurological conditions like epilepsy and Parkinson's disease.

Area of Science:

  • Neuroscience
  • Medical Informatics

Background:

  • Electroencephalogram (EEG) data analysis is crucial for diagnosing neurological disorders.
  • Existing methods for EEG analysis can be limited in scope and application.
  • Brain electrical activity mapping offers a visual and quantitative approach to EEG interpretation.

Purpose of the Study:

  • To develop and present a PC-based program for comprehensive EEG data analysis.
  • To implement advanced brain electrical activity mapping techniques within the software.
  • To evaluate the program's utility in clinical settings for neurological conditions.

Main Methods:

  • The program utilizes a PC platform operating under MS-DOS.
  • It incorporates various map interpolation algorithms, including nearest neighbors and spherical splines.
