How aging affects working-memory neuron firing rate and how to improve it

Yale University researchers have found that neural networks in the brains of the middle-aged and elderly have weaker connections and fire less robustly than in youthful ones. “With normal aging, there are impairments in the working memory functions of the prefrontal cortex (PFC)”, says Amy F. T. Arnsten, professor or neurobiology at Yale University Medical School. (...) Know more at http://goo.gl/trDCb.

Meditation changes brain’s physical structure

Meditation may have potential to change the brain’s physical structure, researchers at the University of California, Los Angeles, have found. People who meditate have stronger connections between brain regions and show less age-related brain atrophy, according to the researchers. Stronger connections influence the ability to rapidly relay electrical signals in the brain.(...) Know more at http://goo.gl/gHslB.
