Mapping interictal epileptic discharges using mutual information between concurrent EEG and fMRI

Dimitri Nestor Alice Van De Ville, François Lazeyras

Objective: The mapping of haemodynamic changes related to interictal epileptic discharges (IED) in simultaneous electroencephalography (EEG) and functional MRI (fMRI) studies is usually carried out by means of EEG-correlated fMRI analyses where the EEG inf ...

Capacitive Detuning Optimization for Wireless Uplink Communication in Neural Implants

Catherine Dehollain, Gürkan Yilmaz

This study presents a wireless energy and data transfer system for neural implants with an emphasis on epilepsy monitoring. A wireless uplink data transmission system is built upon a remote powering system based on magnetic coupling which has been implemen ...

The Future of Intracranial EEG Recording in Epilepsy: a Technological Issue?

Alexandre Schmid, Catherine Dehollain, Mahsa Shoaran, André Mercanzini, Yusuf Leblebici

Intracranial EEG information used for epilepsy surgery has been provided from large widely spaced electrodes over a narrow bandwidth. However, over the last decades, research on animal and more recently on human, promoted by increased interest in developin ...

Whole-brain structural connectivity in temporal lobe epilepsy: a Diffusion Spectrum Imaging study

Jean-Philippe Thiran, Alessandra Griffa, Alessandro Daducci, Alia Lemkaddem, François Lazeyras

Introduction: Medial Temporal Lobe Epilepsy (mTLE) with hippocampal sclerosis is the most frequent cause of drug-resistant focal epilepsy in adults. These patients suffer from widespread subtle white matter abnormalities and abnormal functional connectivit ...

Generation of highly confined optical bottle beams by exploiting the photonic nanojet effect

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the generation of photonic nanojets, which resemble optical bottle beams. They are realized by manipulating the illumination of dielectric microspheres. As illumination we use the outer region of deliberately truncated Bessel-Gauss beam or a f ...

Different emotional disturbances in two experimental models of temporal lobe epilepsy in rats

Maria del Carmen Sandi Perez

Affective symptoms such as anxiety and depression are frequently observed in patients with epilepsy. The mechanisms of comorbidity of epilepsy and affective disorders, however, remain unclear. Diverse models are traditionally used in epilepsy research, inc ...

Self-paced Movement Intention Detection from Human Brain Signals: Invasive and Non-invasive EEG

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Eileen Lew Yi Lee, Huaijian Zhang

Neural signatures of humans’ movement intention can be exploited by future neuroprosthesis. We propose a method for detecting self-paced upper limb movement intention from brain signals acquired with both invasive and noninvasive methods. In the first stud ...

Abnormal self-location and vestibular vertigo in a patient with right frontal lobe epilepsy

Olaf Blanke, Lukas Heydrich, Christophe Lopez

We describe the case of a 33-year-old man with complex partial seizures characterized by the feeling of being projected outside his body, including dissociation of "mind and self from body" (disembodiment), followed by vestibular vertigo due to right front ...

Whole-brain structural connectivity in patients with focal epilepsy studied with MRI diffusion spectrum imaging (DSI)

Jean-Philippe Thiran, Tobias Kober, Reto Meuli, Leila Cammoun, Alia Lemkaddem, François Lazeyras, Christoph Michel

In patients with focal epilepsy, diffusion MRI often reveals structural changes extending beyond visible lesions or show structural abnormalities even when the clinical scans are normal. MR Tractography based on diffusion tensor imaging allows non-invasive ...

Speech arrest with stimulation may not reliably predict language deficit after epilepsy surgery

Olaf Blanke

The authors present a patient in whom electrical cortical stimulation of the posterior temporal cortex induced speech arrest, comprehension deficits, and other language-related impairments. This area was ultimately resected because of persistence of a seve ...
