1. 17663151. The supplementary motor area (SMA) is a region located within each cerebral hemisphere at the posterior medial border of the frontal lobe. It is considered to play an important role in planning, initiating and maintaining sequential motor actions. In this report, we aimed to confirm or invalidate the somatotopic organization of the ...

The supplementary motor area (SMA) is a superordinate control region for speech and language processing. •. The posterior/anterior dimension reflects a subdivision into articulatory versus semantic aspects of language. •. The SMA plays an important role for the integration of subcortical functions.

Supplementary motor area (SMA) syndrome is a common, transient postoperative complication of intra-axial tumor resections involving the SMA and posterior cingulate …

The medial superior frontal cortex (SFC), including the supplementary motor area (SMA) and presupplementary motor area (preSMA), is implicated in movement and cognitive control, among other functions central to decision making. Previous studies delineated the anatomical boundaries and functional connectivity of the SMA.

Medial frontal gyrus - an overview | ScienceDirect Topics. Other clusters of activity appeared lateralized to the left hemisphere and included the posterior aspect of the inferior frontal sulcus (IFS) spreading to the precentral sulcus (PreCS), and the medial frontal gyrus (MedFG) including the supplementary motor area (SMA).

The dorsomedial frontal cortex contains a cluster of areas that are designated the supplementary motor area (SMA), the supplementary eye field (SEF) and the pre …

Consistent with the previous ALE meta-analysis of Go/No-go tasks (Buchsbaum et al., 2005), concurrence of activation was observed in a predominantly right-lateralized network involving the rostral superior medial wall ("pre-SMA"), right middle/inferior frontal gyrus, bilateral inferior parietal regions, occipital regions, putamen …

The SMA occupies the dorsomedial aspect of the superior frontal gyrus, immediately anterior to the foot motor representation, and is bounded medially by the interhemispheric falx and laterally by the premotor cortex (Fig 2A). 23 The cingulate sulcus is inferior to the SMA. The anterior margin of the SMA is defined by a perpendicular line ...

The SMA or SMA proper (Brodmann area 6) is localized in the posterior part of the superior frontal gyrus (Penfield and Welch, 1951). The cingulate sulcus and gyrus demarcate its inferior border. The posterior SMA border is constituted by the precentral sulcus separating it from the leg area of the primary motor cortex.

We found that rTMS over the pre-SMA increased the efficiency of the inhibitory control over prepotent ongoing responses. A significant interaction was present in the left inferior frontal gyrus (IFG) along with an increase in regional cerebral blood flow (rCBF) in the left pre-SMA, left IFG, right premotor and right inferior parietal cortex.

Introduction. The supplementary motor area (SMA) constitutes a distinct region in the dorsomedial superior frontal gyrus. 1, 2 Functionally, it can be divided into the caudal SMA proper, projecting into the corticospinal tract, and the rostral pre-SMA, receiving input from the prefrontal cortex and cingulate motor area. 3 The SMA complex …

The experiment results have demonstrated that medial superior frontal cortex (MSFC) can be successfully parcellated into supplementary motor area (SMA) and pre-SMA, which is consistent with ...

Supplementarymotor area (SMA) syndrome is characterised by transient disturbance in volitional movement and speech production which classically occurs after injury to the medial premotor area. We present two cases of SMA syndrome fol-lowing isolated surgical injury to the frontal aslant tract (FAT) with the SMA intact.

According to this hypothesis, regions of the SMC (possibly the pre-SMA 2,4) may be functionally involved in the computation of abstract vector transformations such as those …

The supplementary motor area (SMA) is thought to play a key role in initiation and control of motor and speech functions (1, 2) Injury to the SMA during surgical excision of medial frontal lobe lesions may also result in severe motor or speech deficits (3–5).These deficits are transient and most patients fully recover from SMA injuries.

The most frequent effects evoked by stimulation of the frontal operculum were language related (29%). The Rolandic area produced most often oropharyngeal symptoms (47%), the parietal operculum produced somatosensory effects (67%), while the temporal evoked auditory (58%) semiology. ...

In the posterior zone, SMA (P1) showed greater coactivation with somatosensory cortices and pIns, whereas pre-SMA (P2) showed greater coactivation with posterior DLPFC, including the inferior frontal junction (IFJ), as well as aIns, regions associated with goal-directed cognition (Nelson et al., 2010; Chang et al., 2013). Within …

It was suggested over 20 years ago that the supplementary motor cortex is involved in self-generated behaviour. Since then, there have been many studies using electrophysiology and brain imaging of the role …

The SMA was manually defined as the area of the MFC in the superior frontal gyrus lying dorsal to the cingulate sulcus, rostral to the primary motor cortex, and caudal to the VCA line, whereas the pre-SMA was manually defined as the area of the MFC in the superior frontal gyrus lying dorsal to the cingulate sulcus, rostral to the VCA line, and ...

Fifteen foci were identified as part of the task-positive network and 15 as part of the task-negative network. The task-positive network consists of regions in the IPS and inferior parietal lobule, precentral sulcus including FEF, dorsal lateral prefrontal cortex, MT +, insula/frontal operculum, and the SMA. The task-negative network consists ...

The supplementary motor area (SMA) is involved in preparing for voluntary movements carried out by the primary motor area (precentral gyrus). The SMA is located …

Crash cushions for impact velocities of 50 km/h, 80 km/h, 100 km/h and 110 km/h have been designed using as the steel honeycomb energy absorber. Due to the high efficiency of the utilized energy absorber we were able to reduce the size of the crash cushions to 2.0 m, 3.3m, 5.1m and 6.5m for the 50 km/h, 80 km/h, 100 km/h and 110 …
