Mood lighting: Penn researchers determine role of serotonin in modulating circadian rhythm
...de the model system for examining entrainment, the synchronization of the internal clock to the environment. "In humans, a light pulse in the early evening delays rhythmif it stays light later, you stay up later," says Sehgal. "Disturbances in the late evening advance the body clockan early dawn leads to an early ri...A new analysis of a standard brain test may help predict dementia
...e feature of those who decline was a change in the synchronization between the two sides of the brain. The source of the theta has been shown to be the hippocampus, a brain region demonstrated in imaging studies with MRI and PET to be impaired in dementia, notes Dr. Prichep....Chaos=Order: Physicists make baffling discovery
...ame intrigued with the concept of disorder-induced synchronization and delved more deeply. Finally, the three put the paper together. Dellen explains that neurons can exhibit synchronous activity in response to a stimulus. To this point, she said, nobody has come up with an adequate explanation. And Wessel said, ...Carnegie Mellon receives NIMH/NSF grant to examine mechanisms that underlie neuronal synchronization
...anding the basic mechanisms that underlie neuronal synchronization -- and how it goes awry -- may allow clinicians to treat the root cause of this disorder and not just the symptoms, Urban added. Urban's NIMH/NSF funding arises from his discovery of stochastic synchrony, a novel mechanism for generating synchronou......emory is an enormous undertaking that will require synchronization of research across multiple disciplines and research models," said Andrea Chiba. "For example, the structure of our center will allow us to carry out similar experiments, simultaneously, in humans, animal models, and computational models. The San Die...
