Abstract: “Paralysis is the loss of the power to move a part of the body due to injury or disease of the nerves that supply the muscles involved in moving the part of the body. In this paper we will deal with the conversion of human thoughts into signals. The cortex which was a part of cerebral cortex is associated with thinking. The thoughts can be converted into (EEG) electroenceplogram signals by fitting electrodes inside the brain. The thoughts converted to EEG signals further used to retrieve the interested images from the database. Section I discusses introduction to the different Disorders that may/may not affect nervous system, BCI systems that helps to overcome these disabilities using Computer Interface , Section II discusses existing systems, while Section III discusses our proposed system.”

Keywords: Image retrieval, EEG, Thought processing, TTD (Thought Translation Device) and Spelling Device
