Ever since scientists observed cortical remapping in the brain of Taub 's Silver Spring monkeys , there has been a lot of research into sensory system plasticity . Huge strides have been made in treating disorders of the sensory system . Techniques such as constraint-induced movement therapy developed by Taub have helped patients with paralyzed limbs regain use of their limbs by forcing the sensory system to grow new neural pathways . Phantom limb syndrome is a sensory system disorder in which amputees perceive that their amputated limb still exists and they may still be experiencing pain in it . The mirror box developed by V.S. Ramachandran , has enabled patients with phantom limb syndrome to relieve the perception of paralyzed or painful phantom limbs . It is a simple device which uses a mirror in a box to create an illusion in which the sensory system perceives that it is seeing two hands instead of one , therefore allowing the sensory system to control the " phantom limb " . By doing this , the sensory system can gradually get acclimated to the amputated limb , and thus alleviate this syndrome
