Raw EEG
The original electrical brain signal recorded from the scalp with no processing.
Raw Impedance
A measure of electrode–skin contact quality used to assess signal reliability; it does not capture neural or muscular activity.
Raw IMU Data
Data from motion sensors that captures movement rather than biological signals.
Transformed EEG
EEG data that has been processed from its raw form.
Classified EEG Output
The result of applying an algorithm or model to EEG data to label or interpret brain states.
EMG Output
Data representing interpreted muscle activity captured by muscle sensors; these are not brain signals.
Classified EOG Output
Data representing interpreted eye‑movement activity produced by eye‑movement sensors.
Timestamps Time markers used to synchronise all data streams.
Experimental Context
Metadata describing what was happening during data collection, such as tasks, conditions, or events; these support the dataset but are not signals.
Combined Data Reports
Compiled datasets or files that may include raw data, processed data, classifications, timestamps, and experimental context.
