“…In particular, each animal individually showed some pallidal activity at least 25 msec prior to the earliest EMG activity. Close inspection of Anderson and Horak's (1985) Figure 8 reveals that this "short" ,25 msec lead time held only for the thoracic paraspinal muscle, whose activity was probably generated by the separate circuit responsible for preparing the postural base for the forthcoming arm movement (Gahery and Massion, 1985). In contrast, pallidal activity led EMG activity in all arm-projection muscles (biceps, deltoid, radialis) by at least 50 msec.…”

“…In particular, an arm movement will be more successful if the muscles controlling body segments that serve as the postural base for the arm are activated before the phasic arm movement is itself initiated. Gahery and Massion (1985) have reported central and muscular postural adjustments with lead times in excess of 25 msec before the onset times for central and muscular arm-movement producing activations.…”

“…[Belenkii 1967] fut parmi les premiers à mettre en évidence l'existence d'ajustements posturaux pré-cédents l'activation de la "chaîne focale" du mouvement intentionnel. Dans la litterature, on les appelle souvent APAs (ajustements posturaux anticipateurs), car leur but serait de conférer au corps une attitude préparatoire favorable à l'execution du mouvement [Gahery 1981]. De par leur caractère anticipatoire (feedforward ), ces APAs seraient gérées au niveau du mode de contrôle pro-actif du schéma corporel (cf section 2.7.2.2) [Cordo 1982].…”

“…L'organisation des APAs dépend de la nature des paramètres du mouvement, ainsi que des conditions posturales [Gahery 1981]. Parmi ces paramètres, la vitesse du mouvement prévu semble particulièrement les influencer , Horak 1984.…”
