Simon Hanslmayr – Neural Oscillations in Human Memory and Attention
Thoughts, feelings, or a face we attend to are produced by orchestrated neural firing patterns in distributed brain networks. Precise timing of this neural activity is required in order to represent information in brain networks and to form lasting memories. Neural oscillations, which are ubiquitous in the human brain, establish such precise timing, which is why I chose to investigate oscillations to understand how the brain implements cognition. To this end my research primarily focused on attention and memory processes in healthy populations, and also in clinical populations. In order to study neural oscillations in humans my lab uses a broad array of electrophysiological and imaging methods from the global scale, such as EEG/MEG, fMRI, combined EEG-fMRI, to the local scale such as intracranial EEG and single unit recordings in humans. Going beyond correlation we study the causal role of oscillations in experiments where we externally perturbate specific oscillations via rhythmic transcranial magnetic stimulation (rTMS) and transcranial alternating current stimulation (tACS) and investigate the impact of such oscillatory perturbations on cognition.
Simon Hanslmayr studied Psychology at the University of Salzburg and finished his PhD in 2005 on the role of alpha oscillations for attention and perception under the supervision of Professor Wolfgang Klimesch. From 2006 until 2010 he did a Postdoc in the lab of Karl-Heinz Bäuml at the University of Regensburg where he focused on the role of brain oscillations for episodic memory. In 2010 he started his own independent research group at the University of Konstanz, funded by an Emmy-Noether award from the German Research Foundation (DFG), where he continued his research on the role of brain oscillations for episodic memory formation. In September 2013 Dr Simon Hanslmayr joined the School where he currently holds a Reader position. His research is funded by several agencies, such as the ERC (Consolidator Grant awarded in 2015; Code4Memory), the Leverhulme Trust, the Royal Society, and the DFG (German Research Foundation).
