It has also been suggested that several beta rhythms exist, each with a different functional significance [74, 77].
Small differences between alpha and beta rhythm networks can be observed, whereas most of those connections' lower FC reached statistical significance for either rhythm.
Suppression of beta rhythms is associated with motor engagement.
Gamma rhythms and beta rhythms have different synchronization properties.
It operates with a pulsed frequency of 17.6Hz, although a recent report on the health effects of mobile phones and transmitters has warned that frequency levels of 16Hz interfere with the Beta rhythm of the human brain, and are particularly damaging for children.
Entrainment of the gamma and beta rhythm might then facilitate or interfere with converging motor input from upstream areas, like the ACC, to M1.
In order to improve the performance of CSP and CSSP, we apply Butterworth filter for EEG signals filtering within a specific frequency band between 8 and 30 Hz, which encompasses both the alpha rhythm (8-13 Hz) and the beta rhythm (14-30 Hz) that relate to motor imagery.
Specifically, they found that the changes in the size of brain waves, called beta rhythms, correlated with the improvements the volunteers made during the rests.
