Document Summary

Part i: principles of sensorimotor function, sensorimotor system arrangement in the cortex. Primary motor cortex: non-cortical motor areas. The sensorimotor system is characterized by 3 principles: 1 hierarchically organized. In the reverse from perceptual system: 2 motor output is guided by sensory input. All of the output you produce is guided by sensory input on a consistent basis to modify the (cid:374)e(cid:454)t steps of (cid:373)oto(cid:396) (cid:373)o(cid:448)"t: 3 learning changes the nature & locus of sensorimotor control. As you acquire motor skills, the system changes. Locations also change depending on level of expertise. Association cortex highest level of organization, starting point of motor action. Secondary motor cortex begins the p(cid:396)o(cid:272)ess of i(cid:374)itiati(cid:374)g (cid:373)oto(cid:396) (cid:373)o(cid:448)"ts. Neurons & muscles allows actual i(cid:374)te(cid:396)a(cid:272)tio(cid:374) (cid:449)ith e(cid:374)(cid:448)"t. In addition to being top-down organized, the sensorimotor system has a parallel structure (signals flow between levels over multiple paths)
