Brain Gate Technology-an Analysis

Abstract

This Paper presents the functioning of a special type of Computer System for paralyzed people. This is possible with the normal chip which is implanted inside the brain’s motor cortex of patients suffering from ALS (Amyotrophic Lateral Sclerosis) to detect brain activity. It is a great device was developed which gave new hope of life to many people. This great invention is known as BRAIN GATE. This paper presents the description of a technique that allows paralyzed patient to have command on computer by using his thought is a great medical achievement. This device is used to help those people who are suffering from serious disorders such as that patient who have no control on their body functions.   Sensor which is placed into the brain cortex contains the tiny chip (smaller than baby aspirin) having 100 electrode sensors each thinner than hair that monitors brain cell activity. The main idea behind the Brain Gate is that to have sensation, and record the feelings or thoughts of patient. In this technology, brain signals which are generated in the mind of the patient are not able to send to their arms, legs, and hands, but they are simplified in the form of cursor movements, providing the patient to control the computer with their thoughts only just as normal individual uses his hands to move the mouse. This paper discusses the technology that it is such a great help or we can say that it is a boon for paralyzed. It can also help the patient with spinal cord injury.
