Sensorimotor System Study Guide Questions and Answers

Sensorimotor System Study Guide Questions and Answers what are motor outputs ANSWER - reaction to sensory and internally generated inputs - guided by sensory inputs How is the sensorimotor system flexible? ANSWER - must be adaptive to achieve goals - requires coordination and sometimes compensation of multiple muscle groups - requires proprioceptive inputs and feedback - adapts to changed in strength and muscle size what are the association ares that intervene between sensory inputs and motor outputs and what do they do ANSWER anterior association cortex = links information from other association areas imp. for memory, planning, forming higher order concept posterior association area = link multimodal sensory integration, imp for guiding perception and language limbis association area = link emotion to sensory input, relate stimuli , imp for learning and memory how is the sensorimotor system organized ANSWER top down processing (commands directed from highest levels - lowest levels, ie. association to muscles) how is there parallel structure in the sensorimotor system ANSWER - Feedback bidirectional • And between functionally segregated levels - Signals flow between hierarchical levels via multiple paths • Association cortex can exert control in more than one way -ex. Association cortex directly inhibit eye blink reflex to put in contacts
