Abstract :

Advanced artificial limbs proven that there is possibility to give patients the feeling that prosthesis is no longer separated from the rest of the body. But absence of touch and sensation in prosthesis delays this advantage. For this reason, much effort has been put to spend to bring sensation to prosthesis. In recent years, there has been remarkable progress in this field and new improvement has been presented in artificial limbs, such as surgically implanted cuff electrons or implants directly through brain. Both these methods will give the patient sensory feedback, but it can be very expensive and high-risk procedure. In this work, we try to open up new possibility for prosthesis to have sensory feedback by using brain illusion. Using recorded brain activities; we can form direct communication between brain and artificial limbs. The objective of work carried out in this project was to investigate how the brain resolves conflicting multisensory evidence during perceptual interference. The rubber hand illusion, mirror hand illusion and invisible hand illusion are the three most famous examples of experiments in which illusionary body ownership is convinced by tactile stimulation of participantâ�?�?s hand. To identify the functional anatomy of these experiments, we used multichannel (14 channel) EEG. Brain response was investigated in 9 healthy (no amputated) candidates, (6 men and 3 women aged 20-32). First experiment on rubber hand illusion (RHI) was carried out under two conditions; hand of volunteer stroke on artificial hand while real hand was hidden from the participantâ�?�?s vision, also, stroking hand and artificial hand without hiding real hand. Second experiment, mirror hand illusion (MHI), also carried out in two conditions, no mirror, looking at physical hand and, mirror, the illusion that hands were stimulated. Third experiment, invisible hand illusion (IHI), is same experiment as RHI without presents of artificial hand. EEG results suggest that gender difference exist in perception of body transfer illusion. Visual input can be induced to trick the brain as 100% of participant had confirmed the statement of â�?�?the fake hand feel like my handâ�?
