These patients do not need to produce conditions of intermittent photic stimulation for self-induction.

These discharges are often provoked by photic stimulation (blinking lights) and sometimes hyperventilation.

Both Huxley and Walter were among the first to articulate the subjective correlates of photic stimulation.

Photic stimulation may refer to:

Academic performance enhancement with photic stimulation and EDR feedback.

These procedures include hyperventilation, photic stimulation (with a strobe light), eye closure, mental activity, sleep and sleep deprivation.

Intermittent photic stimulation may precipitate or facilitate absence seizures; eyelid myoclonia is a common clinical feature.

Photic stimulation may also be used to elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms.

Photoparoxysmal discharges induced by photic stimulation occur in all untreated young patients, but may be absent in older patients or those on medication.

A large area of skin must be stimulated to affect brainwaves, which leaves both auditory and photic stimulation as the most effective and easiest means of affecting brain activity.

More precise investigation can be carried out by combining an EEG with a device producing Intermittent Photic Stimulation (IPS).

With the development of the EEG, Adrian and Matthews published their results showing that the alpha rhythm could be "driven" above and below the natural frequency with photic stimulation.

This approach has been proposed as an alternative to the BOLD fMRI technique and used to detect visual response to photic stimulation, motor activation by finger tapping and activations in language areas during speech processing.

In medicine, Intermittent Photic Stimulation, or IPS, is a form of visual stimulation used in conjunction with electroencephalography to investigate anomalous brain activity triggered by specific visual stimuli, such as flashing lights or patterns.
