Mormann Workgroup - Cognitive und Clinical Neurophysiology

Cognitive Neurophysiology

We are interested in the neurobiology of perception and memory. We explore neuronal behavior in the medial temporal lobe to understand how conscious percepts are transferred into episodic memory traces.

Clinical Neurophysiology

We investigate the pathophysiological mechanisms that lead to the occurrence of epileptic seizures. Our particular focus is on microscopic phenomena such as high frequency oscillations, microseizures, cellular and network behavior.

Methods:

• Single-neuron activity and local field potentials from micro-electrode recordings in humans
• Intracranial electroencephalography (iEEG)
• Sleep polysomnography and sleep stage scoring
• Intracranial electro-stimulation
• Functional magnetic resonance imaging (fMRI)
• Structural magnetic resonance imaging (sMRI)
• Eye tracking
• Olfactometry
• Linear and nonlinear time series analysis
