This document summarizes a seminar presentation on brain gate technology. It begins with an introduction explaining that brain gate is a neuroprosthetic device that converts brain activity into computer commands to help those who have lost limb or body function control, such as spinal cord injury patients. It then describes the working principle where intact neural signals are interpreted by the system to allow the user to control a computer cursor via thought. The document outlines the research done on brain gates in humans and discusses advantages like remote device control, as well as disadvantages like expense and risk. It concludes by discussing applications of brain gate technology and references several related works.

3. INTRODUCTION:
What is brain gate technology?
• Brain gate is a Neuroprosthetic device that
converts brain activity into computer
commands.
• These are the devices which converts the
brains intentions to external actions by using
mechanical components.
• This system is designed to help those who have
loss control of their limps or body functions
such as patients with spinal cord injury.

4. WORKING PRINCIPLE:
• The principle of brain gate neural interface system is that which intact with
brain functions neural signals generated are interpreted by the systems and
a cursor is shown to the user on a computer screen that provides an
alternate brain gate pathway the user can use that cursor to control the
computer just as a mouse is used.

7. ADVANTAGES:
• Controlling remote devices
• Making and receiving Telephone calls
• Accessing the internet
• Turn on or off lights
• Watch and control television
• Use the pc
• Locking or Unlocking doors
• Motorized Wheelchair

8. DISADVANTAGES:
• Expensive
• Risky Surgery
• Not wireless yet
• Difficulty in adaption and learning
• Limitation in information transform

9. APPLICATIONS:
• Researches are going on for brain to brain communication
• Memory upload
• Dream capture
• Use of microcontroller to improve its performance and to reduce
complexity
• Smaller, wireless device.

10. • The idea of moving robots or prosthetic devices not by manual
control, but by thinking (i.e., the brain activity of human subjects) has
been a fascinated approach.
• So this idea helps many patients to control the prosthetic devices of
their own by simply thinking about the task. This technology is well
supported by the latest fields of Biomedical Instrumentation,
Microelectronics; signal processing, Artificial Neural Networks and
Robotics which has overwhelming developments.
• Hope these systems will be effectively implemented for many
biomedical applications.
