Conclusion
“We have provided evidence that daily meditation practice is correlated to both state and trait changes in the observed amplitude of brain electrical oscillations of three different meditation practices. These changes do appear to vary across meditative techniques but one shared feature appears to be enhanced gamma power in the parieto-occipital area. In addition, one specific finding that seems to be unique amongst these three groups of meditative practice is the enhanced alpha power seen as a trait effect in Vipassana practitioners relative to control subjects, Isha shoonya yoga and Himalayan yoga tradition practitioners. Further EEG studies of meditation should favour comparative designs to help move forward our understanding of the neuronal basis of meditation practice.“

Definition. Occipital is an anatomical directional designation and means “towards the back of the head” or “located at the back of the head”.
Richard Davidsons group observed big changes of Gamma waves during practicing meditation in the left-prefrontal lobe. In the present paper, Gamma wave changes during practicing meditation where observed at the back of the head.
