Lutz asked Ricard to meditate on "unconditional loving-kindness and compassion." He immediately noticed powerful gamma activity - brain waves oscillating at roughly 40 cycles per second -�indicating intensely focused thought. Gamma waves are usually weak and difficult to see. Those emanating from Ricard were easily visible, even in the raw EEG output. Moreover, oscillations from various parts of the cortex were synchronized - a phenomenon that sometimes occurs in patients under anesthesia.

In the traditional view, the brain becomes frozen with the onset of adulthood, after which few new connections form. In the past 20 years, though, scientists have discovered that intensive training can make a difference. For instance, the portion of the brain that corresponds to a string musician's fingering hand grows larger than the part that governs the bow hand - even in musicians who start playing as adults. Davidson's work suggested this potential might extend to emotional centers
