ScienceDaily — If you ever argued with your mother when she told you to get some sleep after studying for an exam instead of pulling an all-nighter, you owe her an apology, because it turns out she's right. And now, scientists are beginning to understand why.

In research published recently in Neuron, Marcos Frank, PhD, Assistant Professor of Neuroscience, at the University of Pennsylvania School of Medicine, postdoctoral researcher Sara Aton, PhD, and colleagues describe for the first time how cellular changes in the sleeping brain promote the formation of memories.

ScienceDaily (Feb. 13, 2009) — When someone speaks to you, do you see what they are saying? We tend to think of speech as being something we hear, but recent studies suggest that we use a variety of senses for speech perception - that the brain treats speech as something we hear, see and even feel.

In a new report in Current Directions in Psychological Science, a journal of the Association for Psychological Science, psychologist Lawrence Rosenblum describes research examining how our different senses blend together to help us perceive speech.

ScienceDaily (Mar. 30, 2009) — A visual learning study by scientists at The University of Texas Health Science Center at Houston indicates that viewers can learn a great deal about objects in their field of vision even without paying attention.

Contrary to common belief, attention may actually impair the ability of people to draw conclusions based on the visual images or stimuli they observe, reports Valentin Dragoi, Ph.D., the study’s senior author and an assistant professor at The University of Texas Medical School at Houston.

Sleep May Help Clear Brain For New Learning

ScienceDaily (Apr. 3, 2009) — A new theory about sleep's benefits for the brain gets a boost from fruit flies in the journal Science. Researchers at Washington University School of Medicine in St. Louis found evidence that sleep, already recognized as a promoter of long-term memories, also helps clear room in the brain for new learning.

ScienceDaily  (Feb. 24, 2009) — We all know the feeling: a golden oldie comes blaring over the radio and suddenly we're transported back — to a memorable high-school dance, or to that perfect afternoon on the beach with friends. But what is it about music that can evoke such vivid memories?

Brain Music: Putting The Brain's Soundtracks To Work

Posted May 3rd, 2009 by maarten.vannest...
in
ScienceDaily (Apr. 28, 2009) — Every brain has a soundtrack. Its tempo and tone will vary, depending on mood, frame of mind, and other features of the brain itself. When that soundtrack is recorded and played back -- to an emergency responder, or a firefighter -- it may sharpen their reflexes during a crisis, and calm their nerves afterward.

ScienceDaily  — Researchers at the Swedish medical university Karolinska Institutet have shown for the first time that the active training of the working memory brings about visible changes in the number of dopamine receptors in the human brain. The study, which is published in the journal Science, was conducted with the help of PET scanning and provides deeper insight into the complex interplay between cognition and the brain's biological structure.
