BRAIN GATE TECHNOLOGY INTRODUCTION: Brain-computer interface (BCI) is a fast-growing emergent technology, in which researchers aim to build a direct channel between the human brain and the computer.  It is abbreviated as BCI. DEFINATION:  Brain Gate Technology is a ‘brain-computer interface’ that uses internal neural signal sensor and external processors to convert neural signals into an output signal under the users own control.  This system that allows a quadriplegic man to control a computer using his Thoughts.  Brain Gate is a brain implant system developed by the bio-tech company “Cyber kinetics” in 2003 in conjunction with the Department of Neuroscience at Brown University. WORKING PRINCIPLE: • The Brain computer interface that consist of an Inter neural signal sensor and External Processors. • When a work is done through any part of body then a potential difference is created in the brain. This potential difference is captured by the Sensor. • The sensor is implanted on the surface of brain in the motor cortex area that controls our movement. • The sensor consists of a silicon array about the size of small Aspirin tablet that contain about 100 electrodes each thinner than a human hair that detect brain cell electrical activity. • Brain electrical activity transmitted via fiber optic to the external processor (call Digitizer) convert neural signals into an output signal under the users own control. • The computers translate brain activity and create the communication output using custom decoding software. TYPES 1: Brain Computer interface is of three types based on its features  1-Invasive BCI: Invasive BCIs are implanted directly into the grey matter of the brain during neurosurgery and has the highest quality signals -provide functionality to paralyzed people.  2-Non Invasive BCI: Non-Invasive BCIs do not involve neurosurgery. They are just like wearable virtual reality devices.  3-Partially Invasive BCI: Partially invasive BCI devices are implanted inside the skull but rest outside the brain rather than within the grey matter. -gives a patient the ability to move muscle implants and restore partial movement. Based on the communicative Pathway BCI is classified as follows One Way BCI: Computers either accept commands from the brain or send signals to it (for example, to restore vision) but not both. Two Way BCI: Brains and external devices can exchange information in both directions but have yet to be successfully implanted in animals or humans. APPLICATION: 1. Bionic Eye: Bionic eye is an experimental visual device which will help blind people to see what they want to see. 2. Honda Asimo Control: Honda's Asimo is a robot. Anyone can control its simply by thinking. -Kevin Warwick – The First Human Cyborg Gaming Control: Gaming control using a wearable and wireless EEG-based brain-computer interface device with novel dry

2. INTRODUCTION SLIDE NO :02
☼ What is BGT ?
“Brain Gate Technology is a ‘brain-computer
interface that uses internal
neural signal sensor and external
processors to convert neural signals
into an output signal under the users
own control.”

3. PROCEDURE SLIDE NO :03
☼ How its works ?
 BGT is consist of an Inter neural signal sensor and External
Processors.
 The sensor consists of a silicon array about 100 electrodes that
detect brain cell electrical activity.
 The chip is implanted on the surface of brain in the motor
cortex area that controls movement.
 External Processors convert neural signals into an output signal.
 The computers translate output signal and create the
communication output using custom decoding software.

HOW INFORMATION IS TRANSMITTED??

5. TYPES:
 Based on communicative Pathway :
 One Way BGT: Computers either accept
commands from the brain or send signals to it.
 Two Way BGT: Brains and external devices can
exchange information in both directions.

6. TYPES:
 BASED ON FEATURES :
A. Invasive BGT: Invasive BGT are implanted directly into
the grey matter of the brain during neurosurgery.
B. Non Invasive BGT: Non-Invasive BGT are just like
wearable virtual reality devices.
C. Partially Invasive BGT: Partially invasive BGT devices are
implanted inside the skull but rest outside the brain.

9. ☼ ADVANTAGES
 Allow paralyzed people to control prosthetic limbs with their mind
 Allowing blind person to see.
 Allow a mute person to have their thoughts displayed and spoken by a computer
 Making and receiving telephone calls; Control robots; Use the pc; Locking or unlocking doors etc.

10. ☼ Problems with BGT
 Research is still in beginning stages
 Expensive
 Risky Surgery
 Difficulty in adaptation and learning.

11. SLIDE NO :11
☼ CONCLUSION :
BGT :
 The invention of Brain gate is such a revolution in medical field.
 But it has several complexities. At its current stage, it is not accessible to most people
due to its huge cost.
 BGT have the potential to revolutionize the practice of medical and daily life.
