Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, enabling humans to predict the actions of people with different values than their own. Every day, humans are faced with situations in which they...

Researchers at the RIKEN Brain Science Institute (BSI) have discovered a key mechanism responsible for selectively degrading aggregates of ubiquitinated proteins from the cell. Their findings indicate that the capture and removal of such aggregates is mediated by the phosphorylation of a protein called p62, opening the door to new avenues for treating neurodegenerative diseases such as Huntington's disease and Alzheimer's disease. One of the most important activities of a cell is the...

Highly aggregative and neurotoxic amyloid peptide Abeta43 points the way to new approaches for AD diagnosis and treatmentTokyo, July 4, 2011 - (ACN Newswire) - Researchers at the RIKEN Brain Science Institute (BSI) and their collaborators have shed light on the function of a little-studied amyloid peptide in promoting Alzheimer's disease (AD). Their surprising findings reveal that the peptide is more abundant, more neurotoxic, and exhibits a higher propensity to aggregate than amyloidogenic...

Researchers at the RIKEN Brain Science Institute in Japan have discovered evidence that professional players of a chesslike board game known as shogi have brains that show marked activity in two areas that are less active in amateur players. The professional players use different parts of their brains, the researchers said, which maximize intuition, goal-seeking and pattern-recognition. The scientists used magnetic resonance imaging (MRI) scans to compare the brain activity of amateur and...

New findings reported this week in Science by researchers at the RIKEN Brain Science Institute (BSI) shed first-ever light on the neural mechanisms that enable board game experts to quickly generate optimal moves. Results identify specific brain regions involved in granting shogi masters their superior skill, offering insights into the neural origins of expert intuition. (PRWeb UK) January 20, 2011 What makes experts different from the rest of us? Over the past century, this question has...

Groups of neurons that precisely keep time have been discovered in the primate brain by a team of researchers that includes Dezhe Jin, assistant professor of physics at Penn State University and two neuroscientists from the RIKEN Brain Science Institute in Japan and the Massachusetts Institute of Technology (MIT). "This research is the first time that precise time-keeping activities have been identified in recordings of neuron activity," Jin said. The time-keeping neurons are in two...

The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer. In a new study published in the online, open-access journal PLoS ONE on October 1, researchers at the RIKEN Brain Science Institute in Japan have demonstrated that this can be true. When male birds sang to attract females, specific "reward" areas of their brain were strongly activated. Such strong brain activation resulted in a...
