Breath restriction is used to impair reaching-related action–perception coupling.
We examine θ-EEG activity during encoding of sensorimotor information.
We focus on the activity over the contralateral-premotor and parietal brain areas.
Farthest reaching condition and breath restriction increase θ-EEG synchronization.
θ-EEG sensorimotor rhythm co-modulates with impaired action–perception coupling.
