Corrective loops involved in fast aiming movements: effect of task and environment

摘要: In daily living, we continuously interact with our environment. This environment is rarely stable and living beings show remarkable adaptive capacities. When reach for an object, it necessary to localize the position of this object respect own body before programming adequate arm movement. If target remains stable, programmed movement brings hand near target. However, what happens when suddenly jumps another in space? The aim work was investigate how rapid aiming movements are corrected displaced close onset. Our results reveal that can be modified efficiency trajectory amendments vary according task (directional or direction/amplitude pointings) (structured darkness). We were most interested specific role played by peripheral and/or central feedback information (efferent copy) control movements. suggest two types loops complementary regulation. their predominance varies nature at hand.
