TY - JOUR PY - 2010// TI - Adaptation of eye and hand movements to target displacements of different size JO - Experimental brain research A1 - Schmitz, Gerd A1 - Bock, Otmar A1 - Grigorova, Valentina A1 - Ilieva, Milena SP - 479 EP - 484 VL - 203 IS - 2 N2 - Previous work has documented that the direction of eye and hand movements can be adaptively modified using the double-step paradigm. Here we report that both motor systems adapt not only to small direction steps (5 degrees gaze angle) but also to large ones (28 degrees gaze angle). However, the magnitude of adaptation did not increase with step size, and the relative magnitude of adaptation therefore decreased from 67% with small steps to 15% with large steps. This decreasing efficiency of adaptation may reflect the participation of directionally selective neural circuits in double-step adaptation.
