The equations of each cognitive state.
| Cognitive state | Equation | Equation (over time) | Channel |
|---|---|---|---|
| Attention | (SMRi+Middle βi)/θi | (SMRi+Middle βi)/θi | i=(AF3 + AF4)/2 |
| Mental workload | βi/(θi + αi) | βj/(θj + αj) |
i = AF3, AF4, T7, T8 j = AF4 |
| Vigilance | θ/β, (θ + β)/(α + γ), α/(β + γ) | θ/β | All summed average |
| Mental fatigue | θ/α, θ/β, (θ + α)/β, α/β, (θ + α)/(α + β) | (θ + α)/(α + β) | All summed average |
