Document Summary

Three principles of sensorimotor control: the sensorimotor system is hierarchically organized, motor output is guided by sensory input, learning can change the nature and the locus of sensorimotor control. For example, the association cortex can directly inhibit an eye blink reflex to allow the. Like the orders issued from the office of a company president, the commands that emerge from the association cortex specify general goals rather than specific plans of action. Neither the association cortex or president get involved in specific details. The main advantage of this hierarchical organization is that the higher levels of the hierarchy are left free to perform more complex functions. The sensorimotor system are parallel hierarchical systems; they are hierarchical systems in which signals flow between levels over multiple paths. This parallel structure enables the association cortex to exert control over the lower levels of the hierarchy in more than one way. insertion of a contact lens.
