Segal also questioned the role of GABA in depression. While it may play a role in anxiety disorders, "GABA is not one of the main neurotransmitters that seems to be a part of the depression story," he said. Other neurochemicals -- most notably serotonin -- play much bigger roles in the disorder, he said.
None of this means that the study's findings are without merit, Segal said. "In fact," he said, "we have a program called 'mindfulness-based cognitive therapy,' where we do use yoga, as well as mindfulness meditation," as therapeutic tools. Streeter's findings "suggest the need for more study of these practices," he said.
Streeter agreed that her study is probably just a beginning.
"I think what's important about this study is that it shows that by using really cutting-edge neuroimaging technology, we can measure real changes in the brain with behavioral interventions -- changes that are similar to those that we see with pharmacologic treatments," she said.
