The document summarizes a technical seminar on mind-control technology. It describes how a brain-computer interface system called Brain Gate allows paralyzed individuals to control external devices like computers and prosthetics using only their thoughts by monitoring brain activity. The system includes a microchip implanted in the motor cortex that detects neural signals which are translated by external processors into commands to move a cursor or operate devices. The seminar outlines the development, working principles, components, advantages, and future applications of mind-control technology to restore functionality and independence for the paralyzed.

1. TECHNICAL SEMINAR ON
MIND-CONTROL TECHNOLOGY

2. MIND-CONTROL TECHNOLOGY

3. INTRODUCTION
• It is a mind-to-movement system that allows a quadriplegic man
to control a computer using his Thoughts.
• The system is to help those who have lost control of their limbs,
or other bodily functions, such as patients with spinal cord
injury to operate various gadgets such as TV, computer ,lights,
fan etc.
• It monitors brain activity in the patient and converts the
intention of the user into computer commands
• This can be used to control a robot arm or a cursor on a screen

4. DEVELOPMENT
• Mind-Control 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.

5. Working Principle
• The principle of brain gate neural
interface system is that which
intact with brain function, neural
signals generated are interpreted
by the systems and a cursor is
shown to the user on a computer
screen that provides an alternate
“Mind-Control pathway". The
user can use that cursor to control
the computer, just as a mouse is
used.

6. BCI Technology
• “BCIs” usually connects the brain (or nervous system) with a
computer system.
• A Brain Computer Interface, called as direct neural interface or
brain machine interface is a direct communication pathway between
human or animal brain and an external device.
• Based on the communicative Pathway BCI is classified as follows
 One Way BCI
 Two Way BCI

7. BCI Technology (Cont.)
• 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.

8. Mind-Control plot device

9. • The Neuro chip: A 4-millimeter square silicon chip studded with 100
hair-thin microelectrodes is embedded in the primary motor cortex
region of the brain responsible for controlling movement
• The connector: When the user thinks “move cursor up and down”,
the cortical neurons fire in a distinctive pattern: the signal is
transmitted through the pedestal plug attached to the skull
The components in this system

10. • The converter: The signal travels to a
shoebox-sized amplifier mounted on the
user’s wheelchair, where it’s converted
to optical data and bounced by fiber-
optic cable to a computer.
• The computer: The computer
translates brain activity and creates the
communication output using custom
decoding software.

11. Working
• The Mind-Control neural interface device is a
propriety brain-computer interface that consist of
an Inter neural signal sensor and External
Processors.
• The sensor consists of a tiny chip containing 100
microscopic electrodes that detect brain cell
electrical activity.
• The chip is implanted on the surface of brain in
the motor cortex area that controls movement.
Motor Cortex

12. Working (Cont.)
• External Processors convert neural signals into an output
signal under the users own control.
• In the pilot version of the device, a cable connects the
sensor to an external processor in a cart that contains
computers.
• The computers translate brain activity and create the
communication output using custom decoding software.

14. HOW INFORMATION IS
TRANSMITTED?
• 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
electrodes and is transmitted via fiber optic to the
Digitizer(external processor).

15. • The digitizer converts the signal into some 0’s and
1’s and that is feed into the computer.
• Thus a new path for propagation of brain commands
from the brain to the computer via Brain Gate are
created.
• Now when external devices are connected to the
computer ,then they work according to the thought
produced in the motor cortex.

16. Mind-Control Research in Human
A boon to the paralyzed
• Mathew-Nagel the first person to use the brain-
computer interface to restore functionality lost due
to paralysis…

17. ADVANTAGES
• Controlling remote devices
• Making and receiving telephone
calls
• Accessing the internet.
• Turn on or off the lights
• Control robotic arm
• Watch and control television
• Use the pc
• Locking or unlocking doors
• Motorized wheelchair

18. Future Scope
• Current new advances include a second-generation
interface software M*Power controller
that will enable users to perform
a wide variety of daily activities
without assistances of technician.
• Smaller ,wireless device .
• The user will have an improved
control of respiratory system, limb with
muscle stimulation or robotics.

19. Conclusion
• The invention of Brain gate is such a revolution in
medical field. The remarkable breakthrough offers
hope that people who are paralyzed will one day be
able to independently operate artificial limbs,
computers or wheelchairs.
• The idea of moving robots or prosthetic devices not
by manual control, but by mere “thinking” (i.e., the
brain activity of human subjects) has been a
fascinated approach
