Red-light flashing pens and seizures in children. [PDF]

Dev Med Child Neurol
Guidelines exist to limit seizure‐provoking visual stimuli. However, existing recommendations are not universally applied, and poorly regulated flickering lights are easily encountered in consumer products. Two girls experienced prolonged absence seizures triggered by a red‐light flickering pen.

First Reported Case of CLN5 Disease in Japan: Identification of a Novel Homozygous Pathogenic Variant Through Whole Genome Sequencing. [PDF]

Clin Case Rep
ABSTRACT Neuronal ceroid lipofuscinoses (NCL) belong to a group of inherited neurodegenerative diseases characterized by psychomotor regression, seizures, and visual impairment, resulting from intracellular accumulation of lipofuscin. CLN5, a subtype typically manifesting between ages 4 to 17, is particularly rare in non‐Finnish populations.

Brain Dynamics in Response to Intermittent Photic Stimulation in Epilepsy

International Journal of Online and Biomedical Engineering (iJOE), 2022
Purpose: Routine electroencephalogram (EEG) examinations uses intermittent photic stimulation (IPS) for investigation of the visual cortex EEG responses during resting time. This study aimed to discover brain dynamics effects of IPS in 28 generalized epilepsy patients and 28 healthy subjects.

Frequency of intermittent photic stimulation: Effect on photic afterdischarges, photic driving, and behavioral activity [PDF]

Bulletin of the Psychonomic Society, 1976
The effects of various frequencies of intermittent photic stimulation (1/7, 1/3.5, 1/1, 3/1, 6/1, 9/1, 15/1, 18/1, 24/1, and 60/1 sec) on photically evoked afterdischarges (PhADs), photic driving (PD), and behavioral activity (gridcrossings) were examined in rats.

Gratifying Gizmos for Research and Clinical MEG

Frontiers in Neurology, 2022
Experimental designs are of utmost importance in neuroimaging. Experimental repertoire needs to be designed with the understanding of physiology, clinical feasibility, and constraints posed by a particular neuroimaging method.

Mechanisms of Photosensitive Epilepsies

Pediatric Neurology Briefs, 1999
Intermittent photic stimulation was performed in 21 photosensitive epileptic patients and the relation of the photoparoxysmal response (PPR) to the epilepsy syndrome was determined in a study at the National Epilepsy Center, Shizuoka Higashi Hospital ...

Photic driving in the electroencephalogram of children and adolescents: harmonic structure and relation to the resting state

Brazilian Journal of Medical and Biological Research, 2001
In order to identify latent bioelectrical oscillators, 15 normal subjects (aged 9-17 years, 8 males, 7 females) were subjected to intermittent photic stimulation.

Neurophysiological Findings in Neuronal Ceroid Lipofuscinoses

Frontiers in Neurology, 2022
Neuronal ceroid lipofuscinoses (NCLs) are a heterogeneous group of neurodegenerative diseases, characterized by progressive cerebral atrophy due to lysosomal storage disorder. Common clinical features include epileptic seizures, progressive cognitive and

Rod Driven Frequency Entrainment and Resonance Phenomena

Frontiers in Human Neuroscience, 2016
A controversy exists on photic driving in the human visual cortex evoked by intermittent photic stimulation. Frequency entrainment and resonance phenomena are reported for frequencies higher than 12 Hz in some studies while missing in others.
