What is a stroke "deviation" symptoms?

Stroke "three deviation" refers to the symptoms of hemiplegia, partial body sensation, heminopia three with the same time a group of symptoms, internal capsule is part of the main signs of the disease, were found to have haemorrhagic stroke. (1) hemiplegia : Hemi refers patients Movement Disorders. Disclaimer free movement of nerve fibers called pyramidal tract. The beam from the central hub motor cortex of the brain prior to the pyramidal cell fibers, after downlink to the medullary cystic distal cross to the corresponding contralateral anterior horn cells, and cells previously issued Kok disclaimer skeletal muscle fibers. If the internal capsule hemorrhage, damage to the pyramidal tract is in the cross-plane above, the paralyzing disease in the contralateral there right side of the tongue paralysis and limb paralysis. (2) Partial body sensory dysfunction : Hemi refers to the sensation of pain in patients with a temperature McGREGOR and proprioception obstacles. McGREGOR temperature conduction pain nerve fibers from the skin receptors of nerve endings to the introduction of spinal dorsal horn, crossover cable to the contralateral side uplink, internal capsule posterior branch of the cerebral cortex feeling back after the central hub. Feeling right into the center to stimulate comprehensive analysis of heat, cold or pain stimulus judgment. As part of internal capsule damage, disruption of contralateral side body pain and heat conduction McGREGOR, the pain and temperature sense obstacles. Conduction proprioceptive by stimulating receptors in the spinal cord after the introduction of cable uplink to beam medullary wedge thin beam of nuclear and nuclear, from the issuance of two nerve fibers to cross-walking on the contralateral internal capsule back to the central post. If the internal capsule damage, interrupted the contralateral side of the body proprioceptive conduction, there McGREGOR position Ontology loss of sensory dysfunction. (3) heminopia : depending on the side as the radiation beam and the nerve fibers from the two ipsilateral retinal nerve fiber, internal capsule moments after the extension of the crack-visual center, reflecting the opposite view. If the internal capsule damage, depending on radiation damage, the contralateral heminopia vision.
