Temporal order of activations and interactions during arithmetic calculations measured by intracranial electrophysiological recordings in the human brain - Scientific Reports Arithmetic requires complex and fast processes orchestrated within a large-scale network spanning multiple brain regions. However, reports on the network’s temporal dynamics are scarce. Here, we prese...

Frontiers | Combined MRI morphometry and source imaging guide placement of stereo-EEG electrodes in focal epilepsy with subtle or absent lesions IntroductionPlanning stereo-electroencephalography (sEEG) for focal drug-resistant epilepsy with subtle or absent lesions requires accurate non-invasive spat...

Excited our pilot study is out! In MRI-negative epilepsy, deciding where to place stereo-EEG electrodes is challenging. We show how combining MRI morphometry with electric/magnetic source imaging guides electrode placement.
