Summary
A new Finite Element Model (FEM) of the human head, the ICBM-NY or "New York Head", improves accuracy for electroencephalography (EEG) and transcranial electric current stimulation (tES) when individual MRI data is unavailable.
Area of Science:
- Computational neuroscience and bioengineering.
- Development of advanced computational models for neuroimaging and neuromodulation.
Background:
- Accurate head models are crucial for electroencephalography (EEG) source localization and transcranial electric current stimulation (tES).
- Current models, like Boundary Element Models (BEM) and Finite Element Models (FEM), have limitations in anatomical detail, tissue representation, and field of view.
- Individualized head modeling often relies on costly Magnetic Resonance Imaging (MRI) and standard models may omit critical anatomical features like cerebrospinal fluid (CSF).
Purpose of the Study:
- To introduce a highly detailed Finite Element Model (FEM) of the human head, named ICBM-NY (New York Head).
- To improve the accuracy of EEG source localization and tES targeting in the absence of individual MRI data.
- To provide a comprehensive and accessible head model for research applications.
Main Methods:
- Developed the ICBM-NY FEM based on the ICBM152 anatomical template, extending the field of view to include the neck.
- Performed detailed segmentation of six tissue types (scalp, skull, CSF, gray matter, white matter, air cavities) at 0.5mm³ resolution.
- Compared the ICBM-NY model against individual FEMs, BEMs, and other standard models for EEG source localization and tES targeting accuracy.
Main Results:
- The ICBM-NY model demonstrated superior performance in both EEG source localization and tES targeting compared to FEMs of mismatched anatomies and standard BEMs.
- The model's extended field of view and detailed tissue segmentation, including CSF, significantly impacted current-flow patterns positively.
- Performance evaluations showed ICBM-NY reduced errors in source localization and targeting accuracy.
Conclusions:
- The ICBM-NY (New York Head) model represents a significant advancement for head modeling in neuroscience research.
- It offers a more accurate and detailed alternative to existing models, particularly when individual MRI data is not feasible.
- The authors propose ICBM-NY as a new standard for EEG and tES studies, with all model data made publicly available.
