Source-space EEG neurofeedback links subjective experience with brain activity during effortless awareness meditation
Neuroimage February 26, 2016 R. Lutterveld, Sean Dae Houlihan, Prasanta Pal et al.
In both novice and experienced meditators, decreased activity in the posterior cingulate cortex (PCC) corresponded with the subjective experience of effortless awareness during meditation. Participants could volitionally control the PCC signal in the direction associated with that state. Novice meditators achieved the target state a median of 77.97% of the time, and experienced meditators a median of 89.83% of the time. Median confidence ratings linking PCC activity to effortless awareness were 8 out of 10 for novices and 9 for experienced meditators. The findings suggest EEG neurofeedback from the PCC could serve as a tool for meditation training.
