Nat Commun: A new way for brain cells to communicate

19, 2020 /----- In a new study published in the journal Nature Communications, the University of Helsinki and the Center for Neuroscience at the University of Alto, J. Professor Matias Palva and research director Satu Palva's team worked with the University of Glasgow and the University of Genoa to develop a new coupling mechanism that links neuron networks using records from the human brain.
neuron oscillation is an important part of human brain function.
they regulate communication between neural networks and the processing of information performed by the brain by adjusting the rhythm of neuron groups and synchronizing brain regions.
(photo source: www.pixabay.com) is known to have a frequency of more than 100 Hz of high-frequency oscillations indicating the activity of small neuron populations.
, so far, they are considered only local phenomena.
new findings suggest that high-frequency oscillations of more than 100 Hz are also synchronized in multiple brain regions.
findings suggest that strict scheduled communication between brain regions can be achieved through high-frequency oscillations.
the researchers observed that high-frequency oscillations between neuron groups were synchronized, and that brain structures across objects had similar structures, but occurred in a single band.
performing visual tasks causes high-frequency oscillation synchronization in specific brain regions responsible for task execution.
observations show that high-frequency oscillations are transmitted from one small group of neurons to another in the brain's "packet."
discovery that high-frequency oscillations are synchronized between brain regions is the first evidence that such packets are transmitted and received over a wider range than a single location in the brain.
findings could also help understand how healthy brains process information and how brain diseases change that.
