Comparability of Functional MRI Response in Young and Old During Inhibition [PDF]

, 2004
When using fMRI to study age-related cognitive changes, it is important to establish the integrity of the hemodynamic response because, potentially, it can be affected by age and disease.

Electroencephalography in the Diagnosis of Genetic Generalized Epilepsy Syndromes

Frontiers in Neurology, 2017
Genetic generalized epilepsy (GGE) consists of several syndromes diagnosed and classified on the basis of clinical features and electroencephalographic (EEG) abnormalities. The main EEG feature of GGE is bilateral, synchronous, symmetric, and generalized

Flicker-light induced visual phenomena: Frequency dependence and specificity of whole percepts and percept features [PDF]

, 2011
Flickering light induces visual hallucinations in human observers. Despite a long history of the phenomenon, little is known about the dependence of flicker-induced subjective impressions on the flicker frequency.

Subdural electrode recording of generalized photoepileptic responses

Epilepsy and Behavior Case Reports, 2015
We evaluated the spatiotemporal distribution of photic driving (PDR), photoparoxysmal (PPR), and photoconvulsive (PCR) responses recorded by intracranial electrodes (ic-EEG) in a patient with generalized photosensitivity and right frontal lobe cortical ...

EEG Spectral Exponents and Visual Chirp Responses Mirror Anti‐Seizure Medication Load in Refractory Focal Epilepsy

Annals of Clinical and Translational Neurology
Objective Quantitative markers of cortical excitability may help identify responders to anti‐seizure medications (ASMs). We studied the relationship between ASM load and two electroencephalography (EEG) markers of cortical excitability in people with ...

Bioelectric signal analysis and measurement [PDF]

Nonstationary time series techniques are used to analyze EEG signals for the estimation of alertness. A time varying order is extracted in sequential time series measurement of these data and strategies are devised for obtaining optimal representation of
