Topographic aspects of photic driving in the electroencephalogram of children and adolescents

Brazilian Journal of Medical and Biological Research, 2004
The electroencephalogram amplitude spectra at 11 fixed frequencies of intermittent photic stimulation of 3 to 24 Hz were combined into driving "profiles" for 14 scalp points in 8 male and 7 female normal subjects aged 9 to 17 years.

CHD2 variants are a risk factor for photosensitivity in epilepsy. [PDF]

, 2015
Photosensitivity is a heritable abnormal cortical response to flickering light, manifesting as particular electroencephalographic changes, with or without seizures. Photosensitivity is prominent in a very rare epileptic encephalopathy due to de novo CHD2

THE RELATION BETWEEN THE PHOTIC DRIVING OF EEG AND THE RESPONSE EVOKED BY PHOTIC STIMULATION IN MAN

The Japanese Journal of Physiology, 1966
1. The relation between the response to photic stimulation and the photic driving was investigated on 25 students of our school.2. In the eye-closed state, simple sinusoidal waves of large amplitude were obtained by continuous rhythmic photic stimulation of a frequency equivalent to that of the alpha-like waves resulting from photic stimulation.3 ...

The effects of photic driving on mood states

, 1998
The EEG photic driving response is a sensitive neurophysiological measure. It has been used to assess drug effects, forms of epilepsy, neurological status of Alzheimer's patients, and physiological arousal.

Spectral and Bispectral Analysis of the EEG Rhythms in Basal Conditions and During Photic Stimulation

, 2004
The aim of the present study is the quantification of the relationships and the phase coupling among spectral peaks in the EEG signal at different sites of the scalp. 10 normal subjects underwent the study.

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 ...

Dysregulation of photic induction of Fos-related protein in the biological clock during experimental trypanosomiasis

, 1994
The mammalian suprachiasmatic nuclei of the hypothalamus (SCN) serve as pacemaker for circadian rhythms and the immediate-early gene c-fos is known to be induced by photic stimulation in the SCN of rodents. We studied the induction of Fos-related protein
