MNI2CPC

Please Enter the MNI coordinates:

For example:

MNI_X	MNI_Y	MNI_Z	CPC_Pnz	CPC_Pal	Depth (mm)	ScalpError (mm)	CortexError (mm)
-42	44	30	0.273	0.334	11.40 ± 0.69	3.12 ± 1.72	2.78 ± 1.50

The results are derived from an analysis of 114 Chinese participants’ data (age range 18-26; 63 female).

Due to the reduction in electrical field generated by TMS and tES as cortex-scalp distance increases, only cortical targets within 25mm from the scalp (Download Template&Mask) are considered. If the coordinates you entered are beyond this range, no results will be generated.
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.

When you publish results base on MNI2CPC, please cite:

Once you have obtained the Pnz and Pal coordinates from the MNI2CPC, 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 MNI2CPC.
