Uniform decrease of alpha-global field power induced by intermittent photic stimulation of healthy subjects

Brazilian Journal of Medical and Biological Research, 2002
Nineteen-channel EEGs were recorded from the scalp surface of 30 healthy subjects (16 males and 14 females, mean age: 34 years, SD: 11.7 years) at rest and under trains of intermittent photic stimulation (IPS) at rates of 5, 10 and 20 Hz.

The patent foramen ovale may alter migraine brain activity: A pilot study of electroencephalography spectrum and functional connectivity analysis

Frontiers in Molecular Neuroscience, 2023
BackgroundA link has been shown between patent foramen ovale (PFO) and migraine, particularly migraine with aura. However, it is unknown if PFO might cause migraine by altering cortical excitability and neural network, which may lower the threshold of ...

Dithering suppresses half-harmonic neural synchronisation to photic stimulation in humans.

Brain Stimul
Background:: While entraining neural rhythms using brain stimulation has been suggested as a therapeutic mechanism to normalise brain activity in conditions such as depression, chronic pain, or Alzheimer’s disease, periodic stimulation can also ...

Ambient Music Decreases EEG Burst-Suppression Ratio During General Anesthesia in Rats. [PDF]

Sensors (Basel)
During deep anesthesia, the EEG becomes discontinuous. Burst-suppression is often an intended target during deep sedation or medically induced coma. Within this state, anesthetic depth is commonly monitored by the suppression ratio (SR), which expresses ...

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.
