Functional magnetic resonance imaging is growing from showy adolescence into a workhorse of brain imaging. The blobs appeared 20 years ago. Two teams, one led by Seiji Ogawa at Bell Laboratories in Murray Hill, New Jersey, the other by Kenneth Kwong at Massachusetts General Hospital in Charlestown, slid a handful of volunteers into giant magnets. With their heads held still, the volunteers watched flashing lights or tensed their hands, while the research teams built the data flowing from the machines into grainy images showing parts of the brain illuminated as multicoloured blobs. The results showed that a technique called functional...

The latest weapon in the battle over the legitimacy of some functional brain scanning studies is a dead fish. In study titled "Neural correlates of interspecies perspective taking in the post-mortem Atlantic Salmon", researchers scanned 1.7 kg (3.8 pounds) of a dead salmon while it was shown images of humans in various social situations. It's not clear how long the salmon had been dead by the time it was studied, but Craig Bennett at the University of California, Santa Barbara, says he scanned it about an hour after picking it up from the supermarket, so it was definitely already a...

New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism. Using functional magnetic resonance imaging, a team of researchers affiliated with the University of Washington's Autism Center also found that the most severely socially impaired subjects in the study exhibited the most abnormal pattern of connectivity among a network of brain regions involved in face processing. "This study shows that these brain regions are failing to work together efficiently," said Natalia Kleinhans, a research...

The Washington Timeswww.washingtontimes.com Now, there's proof: Men, women differentBy Jennifer HarperTHE WASHINGTON TIMESPublished December 2, 2005 Attention, Dr. Frankenstein, and maybe Gloria Steinem: There are girl brains, then there are boy brains. But there's not one generic human brain, no matter what hand-wringing feminists may insist in their quest for sexual equality.     Some stark new clinical evidence shows that men and women are just not the same upstairs.     "The comedians are right. The science proves it. A man's brain and a woman's brain really do work differently," a research team from the University of Alberta in Canada announced yesterday....
