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

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

Advantages: Disadvantages: Minimal preparation
time
High spatial
Temporal resolution
Not portable
System complexity
Relationship is inherently
lopsided
