Discovery suggests broad implications for giving brain a boost. While it’s well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new study by a team of researchers at Rice University and Houston Methodist’s Center for Neural Systems Restoration and Weill Cornell Medical College, coordinated by Rice’s Valentin Dragoi, has nonetheless uncovered a key mechanism by which sleep enhances neuronal and behavioral performance, potentially changing our fundamental understanding of how sleep boosts brainpower.

The research, published in Science, reveals how NREM sleep — the lighter sleep one experiences when taking a nap, for example — fost...

A new study has found that eating nuts on a regular basis strengthens brainwave frequencies associated with cognition, healing, learning, memory and other key brain functions. In the study titled “Nuts and brain: Effects of eating nuts on changing electroencephalograph brainwaves,” researchers found that some nuts stimulated some brain frequencies more than others.  Some nuts stimulated some brain frequencies more than others. Pistachios, for instance, produced the greatest gamma wave response, which is critical for enhancing cognitive processing, information retention, learning, perception and REM sleep...
