HISTORY
 Started in 1970s
 Mainly for Pilots to control their planes
 Since 1980s research in this field has been restricted to medicine
COGNITIVE ENGINEERING
The process of receiving signals from the thoughts of a person through different methods is known as 'COGNITIVE ENGINEERING'.
Two basic methods
Invasive and
Non Invasive
INVASIVE METHOD
 In this method an electrode called the neurotrophic electrode is implanted in the brain through a brain surgery
 It is implanted in the cerebral cortex just above the ear
 The implant consists of a thin glass cone of the size of a ball point tip
NON-INVASIVE METHOD
 This method doesn’t require a brain implant
 The user wears a cap studded with electrodes These electrodes help in transmitting the signals
BRAIN COMPUTER INTERFACE
 The system which is used to understand the received signals and translate them to the computer is known as Brain-Computer Interface
 This system allows a person to communicate through the electrophysiological signals from his brain
