I am a Newton International Fellow funded by the Royal Society to develop the project “Voluntary Suppression of Unwanted Memories: The Medial Septal Pacemaker Hypothesis” at Michael Anderson’s Memory Control Lab. The goal of this multimodal project is to investigate whether voluntarily stopping retrieval may be accomplished via the suppression of the medial septum, a critical pacemaker for hippocampal theta oscillations. Up to now, my research has been dedicated to investigate how neural oscillations mediate different memory processes in humans. I have specialized on noninvasive electrophysiological techniques such as EEG/MEG and the application of beamformers to infer the sources of oscillatory activity. This methodology is combined with time-frequency spectral analyses to determine changes in regional brain activation, as well as phase-locking methods to investigate long-distance communication between brain regions. During my previous post-doctoral project, I had the opportunity to perform and analyse intracranial EEG (iEEG) recordings and a simultaneous iEEG-MEG recording in patients with epilepsy that were engaged in a virtual navigation task.
