History
Hans Berger
In 1924 ,recorded human brain activity by
means of EEG
For brain diseases
Rudimentary at initial stage

Neural Signal Acquisition Methods:
Invasiveness
SU: Single-unit recording
ECoG: Electrocorticography
EEG: Electroencephalography
…

How BCI works..?Signals from brain to external activity
Reading signals from an array of neurons
Programs to translate signals into action
For example,

BCI v/s Neuroprosthetics
Neuroprosthetics
- connect the nervous system to a device
BCI
- connect the brain with a computer system
similar in experimental methods and surgical
techniques14/07/2014 BRAIN COMPUTER INTERFACES
Advantages: Disadvantages: Minimal preparation
time
High spatial
Temporal resolution
Not portable
System complexity
Relationship is inherently
lopsided

Conclusion:
Promise for rehabilitation
Achieve singularity very soon
Become potentially high impact technology in
machine control
