EEG Spectrograms from 14 Patients During Propofol Anesthesia

EEG spectrogram data from 14 patients undergoing propofol anesthesia infusion, published by Niklas Brake et al. in Nature Communications in 2024. The dataset contains computed spectrograms from the Cz recording electrode, with time encoded relative to the moment of loss of consciousness. It is provided to support the reproduction of figures from the associated manuscript.

Use Cases

• Modeling the neurophysiological basis of aperiodic EEG signals based on the described spectral trends.
• Analyzing EEG spectral changes relative to loss of consciousness (LOC) based on the time-aligned data.
• Validating biophysical models of brain dynamics under propofol anesthesia using the provided spectrograms.

Strengths

• Data is directly linked to a peer-reviewed publication in Nature Communications (volume 15, 2024).
• Time is precisely aligned to a clinically defined event (loss of consciousness at 0 seconds).
• Includes data from 14 human subjects, providing a basis for group-level analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
