When the brain is under pressure, certain neural signals begin to oscillate synchronously – much like a well-rehearsed orchestra. A new study conducted at Johannes Gutenberg University Mainz (JGU) shows for the first time how flexibly this neural synchrony adapts to different situations and that this dynamic coordination is closely linked to cognitive abilities. “Specific […]
Researchers Trace the Evolutionary History of the Circadian Clock in Modern Cyanobacteria
To better understand the circadian clock in modern cyanobacteria, a Japanese research team has investigated ancient time-keeping systems. They studied the oscillation of the clock proteins KaiA, KaiB, and KaiC (Kai proteins) in modern cyanobacteria and compared it with the function of the Kai proteins of their ancestors. Their research findings were published in Nature […]
How Our Daily Rhythm Can be Both Strong and Flexible
The combination of mathematical modeling and experiments identifies the difference in the molecular clockwork of master and slave clock neurons in Drosophila. This solves the long-standing mystery of the molecular mechanisms responsible for the circadian (~24-hour) clock’s paradoxical properties of robustness (strong rhythms) and plasticity (flexible adaptation). How Our Daily Rhythm is Regulated From tiny […]
Timing and Consistency of Activities Lead to Better Fitness
Some people jump out of bed in the early hours of the morning, while others prefer a slower start to the day. Whether you get up with a smile or a groan, scientists say that your internal clock—known as your circadian rhythm—could influence this behavior and much more. Timing of Activities can Play a Role […]
Pressing the Snooze Button After Waking Up: Recommended or Not?
Sleep experts advise against using the snooze button after the alarm clock rings. However, a study led by researchers at Mass General Brigham shows that this practice is widespread: more than 50% of recorded sleep phases end with a snooze alarm, and people spend an average of 11 minutes snoozing. Using data from the sleep […]
