Biography

Biography

Maeike Zijlmans finished her PhD with honors in May 2011 (prof van Huffelen and prof Gotman). Her thesis is about new presurgical techniques to characterize the focus of epilepsy. These techniques included EEG-fMRI, magnetoencephalography (MEG), special EEG electrodes and 3 T MRI. She stayed at the Montreal Neurological Institute for one year where she studied the use of high frequency oscillations (HFOs) in depth EEG in presurgical epilepsy patients.  She applied the acquired knowledge at the UMC Utrecht to record HFOs with corticography during surgery. Another part of the thesis concerns quality of life and coping style in epilepsy.  In 2013 she started her work as clinical researcher at the RMI together with a combined clinical and research position at Epilepsy Institute in the Netherlands Foundation (SEIN). Her research group, consisting of a post-doctoral fellow, 4 PhD students (+1 finished) and several master students, studies HFOs in a large dataset of retrospectively gathered highly sampled intra-operative electrocorticography and she started up a prospective randomized controlled two-center trial comparing the use of visually identified HFOs to spikes during surgery (the HFO trial). In the mean time the group is trying to improve the clinical yield of the HFO-signal using different signal analytic methods, like high frequent network analysis. Her ultimate goal is to find a way to direct the neurosurgeon directly to the epileptogenic tissue. Also, the clinical yield is studied to predict cognitive outcome and to compare HFOs to other disease markers like in tumours. Another part of the research group works on the non-invasive identification of HFOs with EEG and MEG so the biomarker can help understand several epileptic disorders and help with finding the diagnosis and treatment in people with epilepsy.
