BRAIN MACHINE INTERFACE

PRESENTED BY

G.ATCHYUTA KIRAN

A Technical Presentation on

BMI means…Generally in robots

the interface has a sensor with controller or manually through remote control ,joystick.

But here the machines are controlled with the brain as interface. So the name BRAIN MACHINE INTERFACE.

The Electric Brain Our brains are filled

with neurons , individual  nerve  cells connected to one another by dendrites and axons.

Neurons send signals and these signals are generated by difference in electric potential.

Where To Place These ElectrodesStandard “10-20 System”Letter for region

F - Frontal LobeT - Temporal LobeP - Parietal LobeO - Occipital Lobe

ELECTROENCEPHALOGRAM(EEG):

•An ElectroEncephaloGram(EEG) is a measure of the brain's voltage fluctuations as detected from scalp electrodes.

The Brain-Controlled Vehicle

CONCLUSION:“We now have early evidence that a person unable to move their arms, hands and legs can quickly gain control of a system which uses thoughts to control a computer and perform meaningful tasks”.
