Robot-assisted image-guided transcranial magnetic stimulation for somatotopic mapping of the motor cortex: a clinical pilot study. [PDF]

, 2009
Shape and exact location of motor cortical areas varies among individuals. The exact knowledge of these locations is crucial for planning of neurosurgical procedures.

Cortical spreading depression can be triggered by sensory stimulation in primed wild type mouse brain: a mechanistic insight to migraine aura generation

The Journal of Headache and Pain, 2022
Background Unlike the spontaneously appearing aura in migraineurs, experimentally, cortical spreading depression (CSD), the neurophysiological correlate of aura is induced by non-physiological stimuli.

Closed-loop photic stimulation using EEG [PDF]

, 2020
Accumulating evidence indicates that neural oscillations play a central role in brain function, organising and modulating brain activity in response to both bottom-up exogenous stimuli and top-down endogenous dynamics.

Gamma Entrainment in a Large Retrospective Cohort:Implications for Photic Stimulation Therapy for Alzheimer's Disease [PDF]

, 2020
Background: Studies on mice models of Alzheimer's disease (AD) have suggested potential therapeutic benefits of intermittent photic stimulation at 40 Hz.

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.

Influence of photic stimulation and hypothermia on the electromyogram of the developing chick [PDF]

, 1963
As the body temperature of developing chicks between the 18th day of incubation and the 3rd week after hatching was lowered from normal to 16 C, the eye was subjected to photic stimulation and electrical recordings were made from the eye, cerebral lobes,

Photoparoxysmal responses

Arquivos de Neuro-Psiquiatria, 1990
Sixty-five outpatients with photoparoxysmal response (PPR) during routine EEG were studied. The PPR showed prevalence in women (75.4%). Seizures were found in 66.1% of cases.

Photosensitive Self-Induced Seizures Since Childhood

Acta Médica Portuguesa, 2021
A 15-year-old girl was admitted to the emergency room because of a bilateral tonic-clonic seizure. The family reported that the episode began with rapid hand movements in front of the patient’s eyes while staring at the sun. The patient has a history of

Burst-suppression is reactive to photic stimulation in comatose children with acquired brain injury [PDF]

, 2016
Objective: Burst-suppression is an electroencephalographic pattern observed during coma. In individuals without known brain pathologies undergoing deep general anesthesia, somatosensory stimulation transiently increases the occurrence of bursts.

Photic Activation [PDF]

, 1954
It was concluded that one of the most valuable activating method for EEG. is photic stimulation. But the existing photic stimulator is quite expensive.
