Train Your Brain, but Just for the Practiced Task

Search for "brain training" on internet. You'll find online games, software, exercises, even apps, all designed to prepare your brain to do better on any number of tasks.

Do they work? University of Oregon psychologists say, yes, but "there's a catch." The catch, according to Elliot T. Berkman, a professor in the Department of Psychology and lead author on a study published in the Jan. 1 issue of the Journal of Neuroscience, is that training for a particular task does heighten performance, but that advantage doesn't necessarily carry over to a new challenge.

Study Shows How Poor Sleep Affects the Brain in Healthy Young Men
A new study shows that one night of sleep deprivation increases morning blood concentrations of NSE and S-100B in healthy young men and this could be a prelude to brain damage.

The training provided in the study caused a proactive shift in inhibitory control. However, it is not clear if the improvement attained extends to other kinds of executive function such as working memory, because the team's sole focus was on inhibitory control, said Berkman, who directs the psychology department's Social and Affective Neuroscience Lab.

"With training, the brain activity became linked to specific cues that predicted when inhibitory control might be needed," he said. "This result is important because it explains how brain training improves performance on a given task -- and also why the performance boost doesn't generalize beyond that task."

Sixty participants (27 male, 33 females and ranging from 18 to 30 years old) took part in a three-phase study. Change in their brain activity was monitored with functional magnetic resonance imaging (fMRI).

In Stroke Patients, Residual Activity in the Brain Key for Vision Recovery
Scientists know that vision restoration training (VRT) can help patients who have lost part of their vision due to optic nerve damage, glaucoma or stroke regain some of their lost visual functions.

Differences in Brain Structure in Patients With Chronic Pain
Accumulating evidence indicates that chronic pain of different etiologies is often associated with distinct gray matter volume reductions in multiple brain regions.
