Document Summary
Perhaps all but the highest levels of the sensorimotor system have paterns of acivity programmed into them. Complex movements are produced by acivaing appropriate sequences of programs. A given movement can be accomplished various ways, using diferent muscles. Means that central sensorimotor programs must be stored at a level higher than the muscle (as diferent muscles can do the same task) Sensorimotor programs may be stored in secondary motor cortex. Cerebellum and basal ganglia then serve to coordinate the various programs. Sensory informaion that controls central sensorimotor programs is not necessarily conscious. People can efecively interact with objects that they consciously misperceived. Programs for many species-speciic behaviors are established without pracice. Funcional brain-imaging studies in humans have generally supported the indings from more invasive studies of non-human primates: learning changes nature and locaion of sensorimotor control.
