Influence of vision on vibration-induced illusions of limb movement. 1984

J R Lackner, and A B Taublieb

Illusory motion of the unseen stationary forearm can be elicited by vibration of the biceps brachii or triceps brachii muscle. We have studied in 12 individuals how sight of part of the arm alone or in relation to other objects affects such vibration-induced, illusory motion of the forearm. Our findings indicate a complex but systematic influence of vision in attenuating apparent motion of the forearm. They show, too, that the seen and felt positions of the forearm can be dissociated and that physically impossible spatial configurations of the arm can be experienced. These findings have implications for physiological theories of position sense.

UI	MeSH Term	Description	Entries
D007699	Kinesthesis	Sense of movement of a part of the body, such as movement of fingers, elbows, knees, limbs, or weights.	Kinesthesia,Kinesthetic Sense,Movement Sensation,Kinestheses,Kinesthesias,Kinesthetic Senses,Movement Sensations
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D009132	Muscles	Contractile tissue that produces movement in animals.	Muscle Tissue,Muscle,Muscle Tissues,Tissue, Muscle,Tissues, Muscle
D005133	Eye Movements	Voluntary or reflex-controlled movements of the eye.	Eye Movement,Movement, Eye,Movements, Eye
D005385	Fingers	Four or five slender jointed digits in humans and primates, attached to each HAND.	Finger
