When the human brain handles tasks intellectual challenge, groups of neurons tune each other for a split second, and harmonize, then improvise again, according to a new study. This finding could pave the way for more accurate for people with brain disorders marked by well-known fast, slow or chaotic brain waves as neural oscillations treatments. Tracking the changing rhythms of healthy human brain at work advances our understanding of disorders such as Parkinson’s disease schizophrenia until autism , which characterized in part by brain rhythms unusual.
“The human brain has 86 billion neurons all trying to talk to each other in this very dirty, noisy and electrochemical soup,” said lead author, Bradley Voytek of the University of California, San Diego who conducted the study as a post-doctoral fellow in neuroscience at the University of California, Berkeley. “Our results help explain the mechanism of how brain networks quickly come together and separate, as needed,” Voytek said in the article published . in the journal Nature Neuroscience Read: Your teeth can tell you if you suffer from Alzheimer’s disease and Parkinson
Voytek and fellow researchers measured the electrical activity in the brain of cognitively healthy epilepsy patients. They found that as mental exercises became more demanding, theta waves in four to eight hertz or cycles per second synchronized within the frontal lobe of the brain, allowing you to connect with other brain regions such as the motor cortex. “In these short moments of synchronization, fast communication occurs as neurons from brain regions lock at these frequencies, and this measure is critical in a variety of disorders, Voytek said.
Previous experiments in animals have shown how brain waves control brain activity There are five types of brainwave frequencies. – Gamma, Beta, Alpha, Theta and Delta -. and each is believed to play a different role in people with autism connection between alpha waves and neuronal activity has been found to weaken when processing emotional images people with Parkinson’s disease show abnormally strong beta waves in the motor cortex This blocks the neurons in the wrong slot and inhibits the movement Read:… New treatment options for brain disorders in the way
