Photosensitive epilepsy (PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns. PSE affects approximately one in 4,000 people (5% of those with epilepsy).
It is used by scientists to study the effects of repeated seizures on the brain. [1] A seizure may increase the likelihood that more seizures will occur; an old saying in epilepsy research is "seizures beget seizures". [1] Repeated stimulation "lowers the threshold" for more seizures to occur. [4] The brains of experimental animals are ...
The epileptic seizures can be of different types depending on the part of the brain that was affected, seizures are classified in 2 main types partial seizure or generalized seizure. [ 1 ] Once a child has their first seizure or suspect seizure, they should be referred to specialized paediatrician in epilepsy and seizures to assess the seizure ...
Later, when the subjects were shown new images in the fMRI, the system detected the patient’s brain waves, generated a shorthand description of what it thinks those brain waves corresponded to ...
Shortly after the incident, speaking to USA Today, Mike Lazzo, vice president of programming for Cartoon Network, reassured parents that American children were unlikely to suffer seizures provoked by cartoons as U.S. networks at the time rarely aired anime, which he argued was substantially different to animation aired on Cartoon Network.

A drawing of the human brain showing the thalamus and cortex relative to other structures. The spike-and-wave pattern seen during an absence seizure is the result of a bilateral synchronous firing of neurons ranging from the neocortex (part of the cerebral cortex) to the thalamus, along the thalamocortical network. [2]
The condition, which occurs due to a portion of the skull being misshapen or too small, can cause symptoms like headaches, dizziness and vertigo, weak muscles, difficulty with balance or ...
Epileptic auras are subjective sensory or psychic phenomena due to a focal seizure, i.e. a seizure that originates from that area of the brain responsible for the function which then expresses itself with the symptoms of the aura. It is important because it makes it clear where the alteration causing the seizure is located.
