Some special features of feedback functioning in live movement control are discussed. Taking into account the multicoupling nerve structure of movement apparatus we inevitable are faced with a question about principles based in clousing of chanals’ central endings ensemble, which afferentiates movement, on effector centres ensemble which controls muscle periphery. When we speak about movement skill development such afferent-efferent connections (reciphering, as N.A.Bernstein named them) which would be adequate to perform given motor task do not exist in advance and they must to be developed during performing that task. The main role here play human perception of the information resulted from movement performance on the level of motor-sensory transition, when multidimensional vector of muscle dynamics transforms into dynamics of outer object environment. On the basis of selection of perseptual data new feedback structure is created which ensures steady functioning of the effectory patterns finded durng practice.
