The role of the supplementary motor area (SMA) in word production
Open accessAbstract
The supplementary motor area (SMA) is a key structure for behavioral planning and execution. Recent research on motor control conducted with monkeys and humans has put to light an anatomical and functional distinction between pre-SMA and SMA-proper. According to this view, the pre-SMA would be involved in higher level processes while the SMA-proper would be more closely tied to motor output. We extended this general framework to the verbal domain, in order to investigate the role of the SMA in speech production. We conducted two speech production experiments with fMRI where we manipulated parameters such as familiarity, complexity or constraints on word selection. The results reveal a parcellation of the SMA into three distinct regions, according to their involvement in different aspects of word production. More specifically, following a rostrocaudal gradient, we observed differential activations related to lexical selection, linear sequence encoding and control of motor output. A parallel organization was observed in the dorsolateral frontal cortex. By refining its anatomical and functional parcellation, these results clarify the roles of the SMA in speech production.

“A rostrocaudal gradient distinction was made between the pre-SMA and the more posterior SMA-proper: During silent articulation, the pre-SMA was associated with sequencing abstract motor plans while the SMA-proper was associated with the control of motor output (Alario et al., 2006).”

“These data and recent imaging findings have led a number of investigators to conclude that the SMA plays a critical role in controlling the initiation of speech motor commands (eg, Alario, Chainay, Lehericy, & Cohen, 2006 ; Bohland & Guenther, 2006 ; Jonas, 1987 ; Ziegler et al, 1997 ).”

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.
