Investigation of photic stimulation response with time-frequency based parameters [PDF]

, 2010
In this study, the time-frequency energy distribution based analyses of photic stimulated EEG signals are shown for diagnosis of brain diseases. The recorded EEG signals from healthy and diseased subjects are analyzed by Pseudo Wigner-Wille Distrubution ...

A validation study for a consumer-grade auditory-visual stimulation device

Current Directions in Biomedical Engineering, 2022
Self-care and improving one’s well-being has been growing rapidly in recent years for manifold reasons (e.g. higher workload, corona pandemic). Consumer-grade noninvasive stimulation devices are therefore on the rise to counteract the occurrence of mood ...

Components of generalized onset seizures with focal evolution progressing to bilateral tonic–clonic seizures using quantitative electroencephalography in children: Focal or generalized?

Epilepsia, EarlyView.
Abstract Absence seizures evolving to bilateral tonic–clonic seizures may have focal or asymmetric clinical features. Using quantitative electroencephalography (EEG) may evaluate this phenomenon and the involved neuronal network. We conducted a retrospective chart review of pediatric patients with generalized epilepsy and normal brain magnetic ...

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.

Biometric Authentication from Photic Stimulated EEG Records

Applied Artificial Intelligence, 2021
Studies on brain biometrics have shown that electroencephalogram (EEG) signals encourage more secure authentication. The uniqueness, persistence, universality and robustness of EEG signals against fraud attacks offer potential for highly secure biometric

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

Surgical immobilization of the eye and pupil, permitting stable photic stimulation of freely moving cats [PDF]

, 1966
A technique is described of surgical immobilization of the eye and pupil (motor denervation) so that photic stimulation with constant characteristics is possible in the freely moving animal ...

Maternal olfactory cues synchronize the circadian system of artificially raised newborn rabbits. [PDF]

PLoS ONE, 2013
In European newborn rabbits, once-daily nursing acts as a strong non-photic entraining cue for the pre-visual circadian system. Nevertheless, there is a lack of information regarding which of the non-photic cues are capable of modulating pup circadian ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Evaluation of Electroencephalogram Using Exact Low-Resolution Electromagnetic Tomography During Photic Driving Response in Patients with Migraine [PDF]

, 2019
Background: Photophobia is a common feature of migraine, which may involve abnormal cortical information processing. In electroencephalograms (EEG), photic driving is known as a reaction to visual stimulation. Both photophobia and photic driving response
