Text: Breakthrough study on EEG of meditation Long-term meditators self-induce high-amplitude gamma synchrony during mental practice, by Antoine Lutz, Lawrence L. Greischar, Nancy B. Rawlings, Mathieu Ricard and Richard J. Davidson, in The Proceedings of the National Academy of Sciences USA 101(46)16369-16373, 2004 The challenge in studying consciousness has always been to match subjective, first person accounts with objective, third person measurements. Consciousness is, after all, publically unobservable. So there exists a dichotomy between phenomenological descriptions on the one hand and, on the other hand technologies such as fMRI and EEG which map brain activities correlating with cognition and consciousness. http://www.quantumconsciousness.org/EEGmeditation.htm
