EEG2CPC
For example:
| Landmark | CPC_Pnz | CPC_Pal | Scalp Error (mm) |
|---|---|---|---|
| C3 | 0.498 | 0.300 | 1.11 ± 0.51 |
The results are derived from an analysis of 114 Chinese participants’ data (age range 18-26; 63 female).
Due to recent algorithm optimizations, the CPC coordinates corresponding to the 10-20 landmarks have slight differences from those mentioned in the manuscript.
Please be aware that these results are for research purposes only, and we are not responsible for any consequences arising from their use for other purposes.
Once you have obtained the Pnz and Pal coordinates from the EEG2CPC, you can gain a better understanding of how to manually locate the position on the scalp by watching the instructional video provided below from YouTube, or clicking the Bilibili link (Jiang et al., Brain Stimulation, 2022). Furthermore, the transcranial navigation system can be utilized for a more precise option (Xiao et al., Science Advances, 2018).
Note: The instructional video demonstrates the SGP manual measurement method, which uses CPC coordinates (Pnz and Pal) to represent positions on the scalp. While the SGP system includes an additional coil orientation parameter (Φ) for TMS applications, you only need the Pnz and Pal to complete the positioning when using coordinates obtained from EEG2CPC.
