Researchers performed the first recordings of prefrontal cortical (PFC) neurons from aged monkeys performing a spatial working memory task. They found a marked, age-related reduction in the persistent network firing that is essential for working memory, the building block of higher cognition.
A new study published July 27 in the journal Nature shows that the neural networks in the brains of the middle-aged and elderly have weaker connections and fire less robustly than in youthful ones. Intriguingly, note the scientists, the research suggests that this condition is reversible.
Feel uneasy with an anthropomorphic robot, playing a video game or watching an animated movie, where the human characters are realistic but not quite right? If yes, then you’ve probably visited what’s called the “uncanny valley.”
At the White House, President Barack Obama met the seven U.S. recipients of the 2010 Kavli Prizes to recognize and honor their seminal contributions to the three fields for which the Prizes are awarded -- astrophysics, nanoscience and neuroscience.
A new study shows monkeys can visualize alternative, hypothetical outcomes, and pinpoint areas of the brain where this process takes place and may give scientists new clues into how to treat diseases such as depression and schizophrenia.
Members of four Kavli Insttutes have been elected to the National Academy of Sciences: Paul McEuen, Director, KIC; Boris Shraiman, permanent member, KITP; Michael Goldberg, member, KIBS; and X. Sunney Xie, participant in the KIBST.
The Society for Neuroscience (SfN) has been awarded $1.53 million in funding over six years to create and maintain BrainFacts.org, a unique nonprofit online source for authoritative public information about the progress and promise of brain research.
Publishing in the journal Cell, remarkable progress in understanding how stem cell biology works has been reported by an interdisciplinary team of leading scientists from biology, physics, and engineering.
