Examples
This gives neuroscientists a new tool to dissect both the regular waves and the aperiodic activity in order to disentangle their roles in behavior, cognition and disease.
In a new paper published in Developmental Cognitive Neuroscience, Schaworonkow and Voytek found large changes in aperiodic activity during the first seven months of life.
Voytek’s code has driven a lot of recent research, but it isn’t the only game in town for aperiodic noise analysis.
In their paper, Lendner and her co-authors argue that aperiodic signals can serve as a unique signature to measure a person’s state of consciousness.
With Voytek’s software, Lendner and her colleagues found that in the aperiodic noise of test subjects’ EEGs, the high-frequency activity dropped off faster during REM sleep than when they were awake.
