Utility of EEG in the diagnosis of Efavirenz neurotoxity in HIV positive patients at a South African tertiary hospital
… with encephalopathy, for which scalp EEG (sEEG) is indicated. Although a characteristic pattern of sEEGs waveforms in this deleterious condition has been suggested before, this has not been studied. Objective: The aim of this study was to investigate the utility of sEEG as a biomarker of …

EXPLORING PHYSIOLOGICAL, PATHOLOGICAL AND PARAPHYSIOLOGICAL BRAIN ACTIVITY ACROSS SCALES WITH SIMULTANEOUS INVASIVE AND NON-INVASIVE EEG
… with invasive stereoelectroencephalography (SEEG) to enhance understanding of brain electrophysiology in pathological, physiological and paraphysiological contexts. The combination of these two methods, known as "co-registration," leverages the high temporal resolution and full-brain coverage …

From thoughts to actions: cracking the neural code across scales and modalities
… multi-subject neural decoding based on sEEG data. This approach accounts for variability in the number and placement of electrodes across individuals by learning neural representations that generalize across-subjects while maintaining subject-specific output mappings. This framework …

A Hidden Markov Factor Analysis Framework for Seizure Detection in Epilepsy Patients
… tested on long-term (2.4-7.66 days) continuous sEEG recordings from three patients and a total of 16 seizures, producing a mean sensitivity of 96.3% across all seizures, a mean specificity of 3.47 false positives per hour, and a mean latency of 3.7 seconds form the actual seizure onset. The …

Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis
… complemented with analyses of stereotactic EEG (SEEG) recordings from epilepsy patients. Here, we showed that naturalistic stroking touch induced spectral changes in alpha, beta, and gamma frequencies in sensorimotor regions and the posterior insula, similar to what has been described previously …

A pilot study toward the development of ERD and SSVEP based hybrid brain computer interface
… method such as surface electroencephalogram (sEEG), able to detect signals from brain activity, this pilot study will look into the development of a hBCI combining the modalities of event-related de-synchronisation (ERS) and steady-state visual evoked potentials (SSVEP). The aim of this …

Organizace funkčních oblastí mozku u epileptochirurgických pacientů
Organizace funkčních oblastí mozku u epileptochirurgických pacientů ABSTRAKT Intrakraniální elektroencefalografie (iEEG) je jednou z vyšetřovacích metod v rámci přípravy kandidátů chirurgické léčby epilepsie. Tato unikátní metoda měření mozkové aktivity představuje vzhledem ke své vysoké prostorové …
