Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

Brain Dynamics

Background:

Understanding normal brain function requires accurate electrographic activity maps.
Normative maps can help identify abnormal brain activity, crucial for neurological disorders.
Scalp electroencephalography (EEG) offers a non-invasive method for brain activity mapping.

Approach:

Constructed normative scalp EEG maps of brain dynamics from 17 healthy controls using source-localized resting-state recordings.
Correlated EEG maps with magnetoencephalography (MEG) and intracranial EEG (iEEG) to assess cross-modal similarity.
Applied normative maps to lateralize abnormal brain regions in epilepsy patients.

Key Points:

Spatial patterns of relative band power in scalp EEG maps were consistent with prior research and temporally stable.
Scalp EEG normative maps showed the highest similarity to MEG and iEEG in the alpha band.
Abnormal temporal regions in epilepsy were successfully lateralized ipsilateral to the epileptogenic hemisphere using normative maps.

Conclusions:

Normative mapping using scalp EEG is feasible and demonstrates spatial stability.
The developed normative EEG maps show potential clinical utility, particularly in epilepsy diagnosis and localization.
Further validation with larger sample sizes and high-density EEG is recommended for clinical application.
