Medial frontal cortex: from self-generated action to reflection on one's own performance
2010, Trends in Cognitive SciencesCitation Excerpt :It would be unreasonable to dismiss these cells as being of no functional importance. Indeed, patients with medial lesions that include the SMA show an increase in simple reaction times to a light, perhaps as the result of a lack of preparation for the stimulus [17]. However, monkeys with lesions in the SMA and pre-SMA do not make any more errors than normal on a visual conditional motor task in which colour cues specify which action should be performed [7].
Cortical adaptations and motor performance improvements associated with short-term bimanual training
2006, Brain ResearchCitation Excerpt :The idea that SMA activity contributes to a decrease in RT is supported further through studies of the SMA and its role in temporal aspects of movement. Research has found that the SMA is important for (1) the precise timing of sequential movements (Halsband et al., 1993), (2) planning several movements ahead (Tanji and Shima, 1994), (3) reacting to unpredictably timed external cues (Thickbroom et al., 2000), and (4) initiating motor plans (Viallet et al., 1995). A lesion of the SMA, leading to a deficit of any of the functional roles listed above, can contribute to an increase in RT.
