Distinct EEG correlates correspond to human handedness
Multiple electroencephalography (EEG) studies demonstrate that distinct neural correlates, hemispheric asymmetries, and motor planning strategies correspond to human handedness.
The retrieved literature contains multiple empirical studies (e.g., papers 0, 1, 7, and 10) explicitly investigating and confirming differences in EEG correlates, such as oscillatory power and event-related potentials, between right-handed and left-handed individuals. No papers contradict the premise that handedness has neurophysiological correlates.

The study demonstrates that hemispheric alpha-power asymmetries underlying affective motivation reverse between right- and left-handers.

The study reports distinct event-related potential (ERP) and frontal-parietal asymmetries between left- and right-handed individuals during corrective voluntary actions.

The study reveals that non-right-handers and right-handers differ significantly in their dynamic EEG asymmetry patterns during cognitive and motor tasks.
