Discrimination of emotional states from scalp- and intracranial EEG using multiscale Rényi entropy. [PDF]
PLoS ONE, 2017 A data-adaptive, multiscale version of Rényi's quadratic entropy (RQE) is introduced for emotional state discrimination from EEG recordings. The algorithm is applied to scalp EEG recordings of 30 participants watching 4 emotionally-charged video clips ...

Electrical Stimulation Mapping of Brain Function: A Comparison of Subdural Electrodes and Stereo-EEG
Frontiers in Human Neuroscience, 2020 Despite technological and interpretative advances, the non-invasive modalities used for pre-surgical evaluation of patients with drug-resistant epilepsy (DRE), fail to generate a concordant anatomo-electroclinical hypothesis for the location of the ...

Mapping the epileptic brain with EEG dynamical connectivity: established methods and novel approaches [PDF]
, 2012 Several algorithms rooted in statistical physics, mathematics and machine learning are used to analyze neuroimaging data from patients suffering from epilepsy, with the main goals of localizing the brain region where the seizure originates from and of ...

Intravenous recording of intracranial, broadband EEG [PDF]
Journal of Neuroscience Methods, 2013 The most direct evaluation of human brain activity has been obtained from intracranial electrodes placed either on the surface of the brain or inserted into the brain to record from deep brain structures. Currently, the placement of intracranial electrodes implies transcranial surgery, either through a burr hole or a craniotomy, but the high degree of ...

fMRI functional connectivity as an indicator of interictal epileptic discharges
NeuroImage: Clinical, 2019 Objective: To explore the relationship between functional connectivity and presence of interictal epileptic discharges (IEDs) in different brain regions in intracranial EEG (iEEG). Methods: We studied 38 focal epilepsy patients who underwent simultaneous

Detection of epileptiform activity in EEG signals based on time-frequency and nonlinear analysis
Frontiers in Computational Neuroscience, 2015 We present a new technique for detection of epileptiform activity in EEG signals. After preprocessing of EEG signals we extract representative features in time, frequency and time-frequency domain as well as using nonlinear analysis.

Normative brain mapping using scalp EEG and potential clinical application
Scientific Reports, 2023 A normative electrographic activity map could be a powerful resource to understand normal brain function and identify abnormal activity. Here, we present a normative brain map using scalp EEG in terms of relative band power.
