Pre-motion positivity during self-paced movements of finger and mouth
Open accessAbstract
The present study investigated the role of pre-motion positivity in movement initiation and the reason why it is not reliably detectable in every study participant. Nineteen right-handed participants performed self-initiated simple movements of the right index finger and mouth while electroencephalography activity was recorded. Most of the participants showed a clear-cut pre-motion positivity with its characteristics varying as a function of the effector involved in the movement. The pre-motion positivity distribution was ipsilateral for finger movements and symmetrical for mouth movements. The results suggest that pre-motion positivity might represent a go-signal to initiate the movement and its occurrence might depend on movement initiation strategies.

The Pre-Motor Positivity is related to motor commands for movement initiation.
“We further investigated the Pre-Motor Positivity (PMP), which has been related to motor commands for movement initiation (Bortoletto, Sarlo, Poli, & Stegagno, 2006;Deecke, Grözinger, & Kornhuber, 1976;Deecke, Scheid, & Kornhuber, 1969).”

The PMP has been suggested to reflect a command for movement initiation and may depend on strategies for movement initiation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
