brain regions

(University of California - Los Angeles) Got memory problems? If you suffer from obstructive sleep apnea, your brain could be to blame.

For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.

Reported in the June 27 edition of the journal Neuroscience Letters, the findings emphasize the importance of early detection of the disorder, which afflicts an estimated 20 million Americans.

(Cell Press) Researchers have mapped the brain regions that process social standing and money rewards, yielding new insights that they said will aid understanding of the basis of social behaviors.

They published their findings in two papers in the April 24, 2008, issue of the journal Neuron.

A brain network linked to introspective tasks -- such as forming the self-image or understanding the motivations of others -- is less intricate and well-connected in children, scientists at Washington University School of Medicine in St.

Louis have learned. They also showed that the network establishes firmer connections between various brain regions as an individual matures.
