Hong-viet ngo

AREAS OF INTEREST

Hong-Viet's (aka Hongi) research focuses on the unique brain rhythms during sleep and their functional role on memory formation and cognition. For this endeavour, he combines EEG and intracranial EEG with different brain stimulation modalities (e.g. auditory or transcranial electrical stimulation) to unravel these underlying neural correlates. Although mainly experimentally oriented, his past work also involved theoretical/computational studies regarding the dynamics of neural networks during sleep.

heidrun schultz

AREAS OF INTEREST

A good night's sleep after learning can improve memory. Heidrun is interested in how the brain boosts memories while it's asleep - in particular, how reactivation during sleep supports the consolidation of recently encoded episodic memories. She combines EEG and fMRI to achieve both temporally and spatially precise measures of memory reactivation in the sleeping brain.

mARIA DEL CARMEN MARTIN-BURO

AREAS OF INTEREST

Maria del Carmen focuses on brain oscillations and functional connectivity during offline periods. She is interested in using these brain correlates to bridge the gap between encoding and retrieval and to unveil memory consolidation processes in humans. To this end, she is currently using magnetoencephalography (MEG) and aims to further extend her research with intracranial recordings (iEEG).

MARIT PETZKA

AREAS OF INTEREST

The ability to remember experiences and past events is substantially supported by consolidation processes during sleep. The broad question Marit is working on is what happens in the human brain during offline periods when fragile episodic memory traces become stable representations. Her PhD project aims at further investigating consolidation processes and specifying the functional significance of fast sleep spindles and slow oscillations for episodic memory formation using EEG.

Nicole el marj

AREAS OF INTEREST

Nicole is interested in exploring the neural mechanisms involved in memory formation and consolidation in typically developing adults and in individuals with substance use disorders. For her ClinPsyD project, she will be investigating episodic memory via auditory cued reactivation using behavioural tasks and EEG.
