Comparative Study of Frequency Recognition Techniques for Steady-State Visual Evoked Potentials According to the Frequency Harmonics and Stimulus Number [PDF]

open access: yesJournal of Biomedical Physics and Engineering
Background: A key challenge in steady-state visual evoked potential (SSVEP)-based brain-computer interface (BCI) systems is to effectively recognize frequencies within a short time window.

Preliminary trial of photic stimulation for premenstrual syndrome

open access: yesJournal of Obstetrics and Gynaecology, 1997
In an open study 17 women with confirmed, severe and long-standing premenstrual syndrome used photic stimulation with a flickering red light, every day for up to four menstrual cycles. At the end of treatment prospectively recorded median luteal symptom scores were reduced by 76% (95% confidence interval 54-93, P < 0.001), with clinically and ...

Some Observations on EEG Response to Photic Flicker Stimulation [PDF]

open access: yes, 1961
By applying a combined method of crosscorrelation and frequency analysis to EEG tracings, the average response patterns to photic flicker stimulation with a frequency in the alpha wave range were sorted out, even when the application of the frequency ...

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

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

open access: yes, 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 ...

PMS, EEG, and Photic Stimulation

open access: yesJournal of Neurotherapy, 1997
Abstract Two studies of premenstrual syndrome (PMS), EEG, and photic stimulation have recently been completed at the Royal Postgraduate Medical School, Hammersmith Hospital, London (UK). In a preliminary trial of photic stimulation as a treatment for PMS, seventeen women with PMS were treated with a take-home flashing light device for 15 to 20 minutes ...

The value of repeating intermittent photic stimulation in patients with juvenile myoclonic epilepsy [PDF]

open access: yesRomanian Journal of Neurology
Background. Intermittent photic stimulation (IPS) entails systematic variation of stroboscopic light frequency and may provoke a photoparoxysmal response (PPR) in susceptible individuals. Objectives.

A study of photosensitive epilepsy with particular reference to occipitial spikes induced by intermittent photic stimulation [PDF]

open access: yes
This thesis is the result of an attempt to find means of diagnostic value and understand the underlying mechanisms of photosensitive epilepsy which is a variety of epilepsy where seizures are provoked by photic stimuli.

The eyes of man as a photic bisensor system

open access: yes, 1982
Non-patterned photic stimulation of the eyes of human subjects was obtained by homogeneous illumination of the closed eyes. The subjects perceived a difference between the stimulation intensity of the left and of the right eye as a field of view ...
