Human cerebral potentials and visuomotor learning

Abstract: Cortical potentials during visuomotor learning were investigated in man using two hand tracking tasks: (i) direct tracking (T) and (ii) inverted (mirror) tracking (IT). Negative cerebral potentials were higher during the IT task over several cortical areas but in particular over the supplementary motor area (SMA). The acquisition of motor skill as measured in the IT task, was highly correlated with the enhancement of the negative potential. This correlation only held for the frontolateral and frontomedial cort… Show more

“…It is defined as an event related to a slow cortical potential recorded at the scalp between a warning stimulus (S1) and an imperative stimulus (S2) of a forewarned reaction time task. The CNV has been associated with cognitive processes and anticipation, and can be related to the degree of motivation 3–5 . Rising motivation and elevated concentration increases the CNV amplitude.…”

“…The frontal cortex has been considered to be the prime candidate for generation of the CNV 22 . The CNV is associated with such cognitive processes as that of expectancy, anticipation and preparation for a cognitive decision 2 –4 and its amplitude increases when these functions are present.…”

“…B. Demokrit [9] und China [10] [18]; bei gewissen verbalen Aufgaben ist nur das linke [19], bei visuomo− torischen nur das rechte Frontalhirn erregt [20]. In Versuchen, bei denen zu einem bestimmten Zeitpunkt ein visueller Sinnes− reiz erwartet werden muss, sieht man infolge der hohen zeitli− chen Auflösung der elektrischen Methode, wie die Spannung vom Frontalhirn zum parietalen Aufmerksamkeitszentrum über− geht [21]; ähnlich bei Aufgaben, bei denen etwas visuell imagi− niert werden soll [22].…”
