1. BRAINGATE SYSTEMS --Converts Thoughts into Actions
Presentation by

2. THEME:-
UNTIL RECENTLY,
controlling computers
by human thought
was science fiction,
but it's rapidly
becoming
science fact.

3. BRAIN Brain is a large “hardware” component made of different organs.
Brain cells communicate with each other
by producing electrical impulses.
This is known as electrical activity of the brain.
Due to this electrical activates brain gains overall controls into it’s hands.

4. COGNITIVE ENGINEERING
The process of receiving signals from the thoughts of a person is known as 'COGNITIVE ENGINEERING'.
Two basic methods –
INVASIVE : This method require a brain implant
NON INVASIVE:
This method doesn’t require a brain implant 4

5. INVASIVE METHOD Principle:-
Here Braingate converts brain activity into computer commands.
Here a sensor is implanted on the brain, and electrodes are hooked up with wires to transmit these signals.
Braingate acts as a interface between the brain and system.

7. NON-INVASIVE METHOD This method uses an EEG
(electro encephalograph) to measure the electrical
activity of the brain
A computer program translates electrical signals
in the brain to physical outputs, which govern
the movements of a computer cursor.
This method doesn’t require a brain implant

8. The user wears a cap studded with electrodes
These electrodes help in transmitting the signals

9. INTERACTION PROCESSES
Signal Detection:-
Detecting the “input signal” and translating it into respective action.
Signal Processing & Translation:-
Removes unnecessary bandwidths and generates accurate signal.
Device Control:-
The user chooses an action by controlling his brain activities, which is classified to corresponding action .
INTERACTION PROCESSES

10. The operation protocol defines the rules and
procedures to be followed while transmitting and
receiving data.

11. A boon to the paralyzed Initial state of process
Matthew Nagle a 25-year old man with spinal cord injury is first patient.
This operation undergone at New England Sinai Hospital in Massachusetts.
Initial state of process
After taking part in a clinical trial

13. OTHER APPLICATIONS Vision of cats Operation on mouse
Operation on monkeys

15. CONCLUSION
The brain-computer interface will one day transform the lives of severely handicapped people, eventually enabling them to operate artificial limbs as easily as if they were their own.
