"Attention regulation and monitoring in meditation" (PDF). A recent article in Trends in Cognitive Sciences on the neuroscience of meditation, focusing on how meditation alters and sharpens the brain's attention systems. The research is being done at the Waisman Laboratory for Brain Imaging and Behavior (previously), who have also recently published research on the "Regulation of the neural circuitry of emotion by compassion meditation" (PDF), which describes how meditation can cultivate compassion by physically affecting brain regions that play a role in empathy. They shared this research with the Dalai Lama at the recent Seeds of Compassion forum.

Ken Wilber can stop his brain waves on demand. This (WMV) is the famous EEG machine recording where Ken Wilber enters various meditative states, one of which is a type of "thoughtless," "image-less," or "formless" state, whose correlate is that his brainwaves come to an almost complete stop, as clearly recorded on this portable electroencephalograph (EEG) machine. Seeing somebody's brainwaves flatline in about 4 seconds is a sight not easily forgotten! Also on YouTube.
