Summary
This study introduces NHP1020, a software tool that automates electroencephalographic (EEG) electrode placement in non-human primates (NHP). This innovation simplifies translational research by enabling faster, standardized EEG grid planning for NHPs.
Area of Science:
- Neuroscience
- Medical Imaging
- Biomedical Engineering
Background:
- Electroencephalographic (EEG) recordings in non-human primates (NHP) are increasingly valuable for translational research.
- Standardized EEG electrode placement is straightforward in humans but complex and time-consuming in NHPs.
Purpose of the Study:
- To introduce a novel surface metric and software package, NHP1020, for automated EEG electrode grid planning in NHPs.
- To overcome the challenges associated with manual and time-consuming electrode positioning in non-human primate research.
Main Methods:
- Developed NHP1020 software utilizing a surface-based spherical metric, analogous to the human 10-20 system.
- The software processes CT and MRI images along with intracranial markers to define electrode positions on the brain surface.
- Enables sharing, importing, and defining standardized electrode grids via high-level commands.
Main Results:
- NHP1020 automates the planning of large, approximately evenly spaced EEG electrode grids for NHPs.
- The software provides fast and automated identification of entire electrode grids based on a 2D surface metric.
- Standardized grids can be defined relative to neural structures or extracranial markers.
Conclusions:
- The NHP1020 toolbox offers a significant advancement for non-human primate EEG research.
- It provides a fast, automated method for identifying electrode grids, improving efficiency and standardization.
- This tool enhances the utility of NHP EEG for translational studies.
