Researchers from Japan's ATR Computational Neuroscience Labs have created a new brain analysis technology that can recontruct images inside of a person's mind and then display them on a monitor. The researchers want to try to view the contents of dreams in the future.
Sounds like either the journalist or the scientist is exaggerating their findings, but I could be wrong. I just have a hard time believing this could be possible. Here's how they are claiming to do it:
'The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. While the fMRI machine monitored the changes in brain activity, a computer crunched the data and learned to associate the various changes in brain activity with the different image designs.
Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the system was able to reconstruct and display what the test subjects were viewing based solely on their brain activity.'
The researchers also discuss applying the technology to reading feelings and complicated emotional states, but may have a difficult time displaying these things on a monitor.
The blog 'Pink Tentacle' says that this research is in the December 11 issue 'Neuron', but I haven't been able to find it.
lolwut? more later... Update - this is being reported about all over the place now. Scientific American also uses Pink Tentacle as a source, but claim that the scientists have 'reported it' to the journal 'Neuron', not that 'Neuron' has published anything about it. Big difference. We'll see where this goes.

Video: Ken Wilbur enters into various meditative states during a EEG Neurofeedback session
Thursday, 30 August 2007
You may have already seen this, but it is new to me. Ken Wilbur narrates a video of his own experience using neurofeedback while navigating various meditative states.
From YouTube:
'We asked Ken to do a short 10-minute commentary on these various meditative states and the corresponding brain-wave patterns that are shown on the EEG machine in the video. Ken enters four meditative states (nirvikalpa closed eyes, nirvikalpa open eyes, sahaj, and mantra-savikalpa), each of which has a very distinctive brain-wave pattern. In his commentary, Ken emphasizes that the patterns shown on this machine may or may not be typical, but they do emphasize that profound consciousness states can be evoked at will, and these show immediate correlation in brain-wave patterns.'
