In a randomized controlled study based in Los Angeles, California, encouraging African-American women aged 60 or over to exercise, in conjunction with scripture reading and group prayer, led to a 78% increase in steps per week, equivalent to about three extra miles. This increase was four times greater than in the control group who were also encouraged to exercise but with no faith based interventions. The results are published today in the Journal of the American Geriatrics Society.
Sensation seeking—the urge to do exciting things—has been linked to dopamine, a chemical that carries messages in your brain. For a new study published in Psychological Science, a journal of the Association for Psychological Science, scientists analyzed genes in the dopamine system and found a group of mutations that help predict whether someone is inclined toward sensation seeking.
Using electrodes to stimulate areas deep within the brain may have therapeutic potential for patients with obsessive compulsive disorder that is refractory to treatment, according to a report in the October issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Impulsive behaviour can be improved with training and the improvement is marked by specific brain changes, according to a new Queen’s University study.
Since the first case description in the 19th century, the causes of Tourette syndrome have been a mystery. Now researchers have identified a rare gene mutation responsible for the disorder in one family. The gene is needed for producing histamine, a small molecule with many roles in the body, including signaling in the brain.
When people think of spinal cord injury, they tend to think of paralysis. But a spinal cord injury can also cause debilitating muscle spasms. Although the drug baclofen can control these spasms, many patients cannot tolerate its side effects, which include general sedation and dizziness. A new study sheds light on how a spinal cord injury leads to spasms, and on the promise of more precisely targeted drugs with fewer side effects.
Psychologists have known for a long time that after you make a choice, you adjust your opinion to think better of the thing you chose. Now a new study has found that this is true even if you don’t know the options that you’re choosing between.
A new look at tests of mental aging reveals a good news-bad news situation. The bad news is all mental abilities appear to decline with age, to varying degrees. The good news is the drops are not as steep as some research showed, according to a study published by the American Psychological Association.
Memory isn’t always reliable. Psychological scientists have discovered all sorts of ways that false memories get created, and now there’s another one for the list: watching someone else do an action can make you think you did it yourself.
A type of neuron that, when malfunctioning, has been tied to epilepsy, autism and schizophrenia is much more complex than previously thought, researchers at MIT’s Picower Institute for Learning and Memory report in the Sept. 9 issue of Neuron.
