- There are two criteria for calculating consciousness (Vigilance):AVPU and GCS (Glasgow).
- These two methods express the consciousness factor Numerically (quantitative (3-15))
- How we can calculate the level of consciousness in the EEG signal?
Yes, but only if you define subjective consciousness in objective terms.
It is not as simple as Parth suggested.

Do You Know?
Please tell me!
The human's idea, about issues, is different.

The different types of frequency band can reflect the different levels of consciounnes of an individual. Delta is the frequency range up to 4 Hz. It tends to be the highest in amplitude and the slowest waves. It is seen normally in adults in slow-wave sleep. Theta is the frequency range from 4 Hz to 7 Hz and this range has been associated with reports of relaxed, meditative, and creative states. lpha is the frequency range from 7 Hz to 13 Hz. It emerges with closing of the eyes and with relaxation, and attenuates with eye opening or mental exertion. Beta is the frequency range from 14 Hz to about 30 Hz. Beta activity is closely linked to motor behavior and is generally attenuated during active movements. Gamma is the frequency range approximately 30–100 Hz. Gamma rhythms are thought to represent binding of different populations of neurons together into a network for the purpose of carrying out a certain cognitive or motor function.
