In the brain found neurons that acts as a metronome


В мозге найдены нейроны, работающие как метроном

Neuroscientists from brown University have discovered a type of neuron that acts as the metronome in the brain.

Scientists from brown University have discovered a new cell type, which regularly counts the time that can serve as the metronome of the biological clock. According to Chris Moore (Chris Moore), Professor of neurobiology, this type of neurons pulsing rhythmically and synchronously, regardless of external influences. “Setting the pace”, the neurons, appears to improve the ability to regulate daily physiological rhythms.

Brainwaves around 40 cycles per second, also known as gamma rhythms, have been studied since the mid 1930-ies in humans and rodents. Earlier laboratory work by Moore showed that the increase in natural gamma rhythms in mice helps them to better perceive sensations from whiskers. The recently discovered “metronomic” neurons, which rotate at a speed of about 40 cycles per second, influence of gamma rhythms, but they do not depend on outside influence.

The results were published in the journal Neuron.
