We interpret the aberrant pattern of beta rhythms observed in our ASD group, especially the increased ERD, as most likely associated with the difficulty of cognitive processes involved in selecting the motor response rather than with a motor deficit itself.

These findings are present across all motor imagery categories and they closely match findings from our previous study on the role of alpha and beta rhythms in sensorimotor networks [44, 104].

Suppression of beta rhythms is associated with motor engagement.
For instance, mu may signify the inhibition of motor output, such that changes in beta rhythms sequencing motor commands remain a simulation, unable to affect actual muscles.
Beta rhythm is obtained in alert subjects; it is a fast, low-voltage rhythm that is distributed over the scalp.
