This document provides an overview of brain-computer interfaces (BCI). It discusses electroencephalography (EEG) and how EEG measures brain electrical activity through electrodes. Different types of BCI devices and electrodes are described. The anatomy of the brain and functional mapping are outlined. Applications of BCI include prosthetic control, communication devices, operator monitoring, forensics, entertainment, health, neuromarketing, and neuroscience. The document also discusses Elon Musk's Neuralink company and its goal of creating brain chips to treat disorders. It concludes with a live demo of a BCI system using an EEG headband and a question/answer session.

9. ELECTROENCEPHELOGRAPHY
EEG
Electroencephalography (EEG) is
the recording of electrical activity
along the scalp. EEG measures
voltage fluctuations resulting
from ionic current flows within
the neurons of the brain
German physiologist and
psychiatrist Hans Berger (1873–
1941) recorded the first human
EEG in 1924

10. EEG
BANDS
Alert | Anxious Thinking
Beta
15 – 32 Hz
Relaxed State | Eye blink
Drowsiness | Idling in
Adults
Adult slow wave sleep
Alpha
8 – 15 Hz
Theta
4 – 8 Hz
Delta
0.5 – 4 Hz
Gamma
> 32Hz
Fastest waves which pass
information rapidly and quietly

11. Involves attaching
electrodes directly to the
brain tissue
Involves putting
electrodes on the scalp of
the patient and taking
