Harris and two co-authors ran 360 statements by 14 adult subjects whose brain activities were then scanned by functional magnetic resonance imaging (fMRI) devices. It suggests that within the brain pan, at least, the distinction between objective and subjective is not so clear-cut. Although more complex assertions may get analyzed in so-called "higher" areas of the brain, all seem to get their final stamp of "belief" or disbelief in "primitive" locales traditionally associated with emotions or taste and odor. Even "2 + 2 = 4," on some level, is a question of taste. Thus, the statement "that just doesn...
Harris says there is no critique of faith hidden somewhere in his brief paper. But his next neurological enterprise may be another matter. He is planning an fMRI run that will concentrate specifically on religious faith, which Harris thinks he now knows how to plumb more deeply. He also plans to set up two different subject groups - the faithful and non-believers. "That way," among other things, he says, "you can ask, 'Do believers believe that Jesus was born of a virgin the same way that nonbelievers believe that Chevrolet makes cars and trucks?'" It may turn out that...
...turns out, the amygdala is indeed a big player in the pathological process of OCD but only one of several players. Functional magnetic resonance imaging (fMRI) and other scanning technologies have allowed researchers to peer deeper than ever into the OCD-tossed brain. In addition to the amygdala, there are three other anatomical hot spots involved in the disorder: the orbital frontal cortex, the caudate nucleus and the thalamus--the first two seated high in the brain, the third lying deeper within...
...staff psychiatrist to make sure I would be able to handle it if I experienced a craving, I was fitted with a tube that carried beer aroma from a vaporizer into my nose. I was then slid into the machine to inhale that still familiar odor while the fMRI did its work...
...probably a case in point. My brain barely lit up in response to the smell of beer inside the fMRI at McLean. "This is actually valuable information for you as an individual," said Scott Lukas, director of the hospital's behavioral psychopharmacology research laboratory and a professor at Harvard Medical School who ran the tests. "It means that your brain's sensitivity to beer cues has long passed...
