How long does a EEG recording session take?
The total duration of a EEG recording session is typically about 15 minutes. This includes preparation and a structured EEG recording with eyes‑open and eyes‑closed phases, each lasting a few minutes.

- Eyes‑closed recording
Each phase has:
- A default duration of 3 minutes
- A configurable range of 2 to 5 minutes per phase
Using default settings, the EEG recording itself lasts around 6 minutes.

Before the recording begins, time is needed to:
- Prepare the user
- Set up the EEG cap and electrodes
- Connect the amplifier
- Check signal quality
Preparation time can vary depending on setup and user conditions.

- Eyes‑closed EEG recording
- Saving or reviewing the recording
When combining preparation and recording, the total session time is typically around 15 minutes.
