Area of Science:

  • Neuroscience
  • Cognitive Science
  • Medical Imaging Analysis

Background:

  • The human brain utilizes interconnected regions for information processing and behavior.
  • Brain diseases can disrupt neural networks directly or through compensatory mechanisms.
  • Understanding these network alterations is crucial for diagnosing and treating neurological disorders.

Purpose of the Study:

  • To review an analytical approach using principal component analysis (PCA) for studying neural networks.
  • To explore the application of PCA in understanding disease-related changes in brain networks.
  • To investigate network abnormalities and reorganization in sensorimotor disorders.

Main Methods:

  • Covariance analysis of functional brain imaging data.
