Juliane Britz is a researcher at the Max Planck Institute for Empirical Aesthetics, specializing in the Department of Cognitive Neuropsychology. Her work focuses on the neural correlates of consciousness through EEG microstate analysis and their relationship to larger brain network dynamics.
Her primary research interests include:
- Consciousness Studies
- EEG Microstates
- Resting-State Networks
- Neuroscience
- Brain Dynamics
- Anesthesia Effects
Dr. Britz has conducted significant research on how brain electrical activity patterns change during different consciousness states, particularly during pharmacologically induced loss of consciousness using Propofol. Her work demonstrates that EEG microstates serve as electrophysiological correlates of fMRI resting state networks, revealing how these brief stable brain configurations (lasting ~70-100 ms) transition rapidly between states. She discovered that the long-range temporal correlations of microstate sequences vary non-linearly with anesthesia depth—decreasing at intermediate sedation levels and increasing again when fully unconscious.
Her research methodology combines simultaneous EEG/fMRI measurements with clinical consciousness assessments (OAA/S scores), showing that EEG microstates exhibit mono-fractal properties with long-range temporal correlations analogous to natural language structures. This characteristic appears fundamental to consciousness, enabling the brain to rapidly adjust to unexpected events. Her findings contribute to understanding critical brain dynamics during consciousness transitions and may provide electrophysiological markers for monitoring anesthesia effects.
