Experienced meditators seem to be able switch off areas of the brain associated with daydreaming, as well as psychiatric disorders, such as autism and schizophrenia, according to a new brain imaging study by Yale researchers. Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. […]

All of us, at times, ruminate or brood on a problem in order to make the best possible decision in a complex situation. But sometimes, rumination becomes unproductive or even detrimental to making good life choices. Such is the case in depression, where non-productive ruminations are a common and distressing symptom of the disorder. In […]
Higher levels of cell chatter boost amyloid beta in the brain regions that Alzheimer’s hits first, researchers at Washington University School of Medicine in St. Louis report. Amyloid beta is the main ingredient of the plaque lesions that are a hallmark of Alzheimer’s.
Watching the brain’s “autopilot” network in real time may help determine the onset of cognitive decline and potentially aid in making an early diagnosis of Alzheimer’s disease, according to researchers at Duke University Medical Center. The results are published in Neurology, the medical journal of the American Academy of Neurology.
Brain scans of children with attention-deficit/hyperactivity disorder (ADHD) have shown for the first time why people affected by the condition sometimes have such difficulty in concentrating. The study, funded by the Wellcome Trust, may explain why parents often say that their child can maintain concentration when they are doing something that interests them, but struggles […]
Neuroscientists at Georgetown University Medical Center can now show, using functional MRI images, why it is that behavior in children and young adolescents veers toward the egocentric rather than the introspective. In findings being presented at the annual meeting of the Society for Neuroscience in San Diego on November 14, the researchers say that the […]
A group of “professional couch potatoes,” as one researcher described them, has proven that even moderate exercise – in this case walking at one’s own pace for 40 minutes three times a week – can enhance the connectivity of important brain circuits, combat declines in brain function associated with aging and increase performance on cognitive […]
A new EEG study conducted on college students at American University found they could more highly activate the default mode network, a suggested natural “ground state” of the brain, during their practice of the Transcendental Meditation (TM) technique. This three-month randomized control study is published in a special issue of Cognitive Processing dedicated to the […]
