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: Interesting Experiment - Richard Dawkins on the God Machine
Wednesday, 19 September 2007
Michael Persinger is a neuropsychologist at Canada's Laurentian University in Sudbury, Ontario. His theory is
that the sensation described as "having a religious experience" is merely a side effect of our bicameral brain's
feverish activities. He has attempted to create experiments to show that when the right hemisphere of the brain
is stimulated in the cerebral region presumed to control notions of self, and then the left hemisphere is called
upon to make sense of this nonexistent entity, the mind generates what is felt as a 'sensed presence.'
Many of Persinger's studies detail the reactions that people have when their temporal lobes are stimulated with complex magnetic fields. Some of the subjects experience a 'sensed presence' in the form of the deity from the culture that they were raised in. They see the God (or spirits associated with their God - the Virgin Mary, Mohammed, etc) that they believe in. Others have had experiences that mimic the feeling that one would have during alien/UFO visitation - these people tend to be more agnostic.
In 2003 the BBC arranged for Prof. Richard Dawkins to be a subject in one of Persinger's experiments.
