Mental Rest and Reflection Boost Learning, Study Suggests

Oct. 20, 2014

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they've learned before may boost later learning.

Neurons in the Brain Tune into Different Frequencies for Different Spatial Memory Tasks

Place cells codes represent upcoming locations at some times and reflect recently visited locations at other times. The findings by Bieri and colleagues show that place cells predict upcoming locations during periods of slow gamma rhythms and encode recently visited locations during periods of fast gamma rhythms.

AUSTIN, Texas  Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists at The University of Texas at Austin.

Brain Scans Show We Take Risks Because We Can't Stop Ourselves

Feb. 4, 2014

AUSTIN, Texas  A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it's probably not because their brains' desire systems are too active, but because their self-control systems are not active enough.
