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

.

Relationship between user and BMI is inherently lopsided.

Conclusion:

Promise for rehabilitation

Achieve singularity very soon

Become potentially high impact technology in

machine control
