8.23 Brain Computer Interfaces Flashcards
1
Q
How can one use information from brain activity?
A
By decoding neural signals into “usable” signals.
2
Q
What is the role of machine learning in BCI?
A
Learn the relationships between brain patterns with possible control outputs
3
Q
When does a neural signal ‘contain information’ about X?
A
When there is a systematic relationship between brain activity and X.
In order to read information from the brain about X one has to decide about what X actually is.
X could in principle be anything ( images / actions / letters / syllables / words/ …), but only if the relationship between neural activity and X is reproducible, can we develop specific BCIs for that X.
