With that new knowledge,  a new study of patient GY, who had  been used extensively to demonstrate the phenomenon of Blindsight (that is to say the ability to discriminate correctly visual stimuli presented to the blind field without conscious awareness) led to interesting findings. The re-examination showed that, when presented with fast-moving, high contrast, visual stimuli in his blind field, he could discriminate their presence and direction of motion consciously, This, in turn, led to a re-classification of blindsight into Type 1 and Type 2 the former adhering to the previous definition of blindsight while the latter acknowledging the fact that the experience of such subjects can be conscious even if much degraded. Only moving objects in the scotoma are visible, static ones being invisible to the patient. The moving objects are not perceived to have color or detail. The subject may only have awareness of the movement without visual perception of it (gnosanopsia), or the general shape of a moving object may be perceivable as a shadow like outline. The syndrome is named after George Riddoch who had been a temporary officer in the Royal Army Medical Corps and examined soldiers who were blinded by gunshot wounds to their brains.At least one patient was able to use a rocking chair—putting non-moving surroundings in relative motion to her head—to improve her motion perception. She eventually was able to do the same with movement of her head. See also

In some places physicians are required by law to report if a person has had a seizure to the licensing body while in others the requirement is only that they encourage the person in question to report it himself. Countries that require physician reporting include Sweden, Austria, Denmark and Spain. Countries that require the individual to report include the UK and New Zealand, and physicians may report if they believe the individual has not already. In Canada, the United States and Australia the requirements around reporting vary by province or state. If seizures are well controlled most feel allowing driving is reasonable. The amount of time a person must be free from seizures before he can drive varies by country. Many countries require one to three years without seizures. In the United States the time needed without a seizure is determined by each state and is between three months and one year.Those with epilepsy or seizures are typically denied a pilot license. In Canada if an individual has had no more than one seizure, they may be considered after five years for a limited license if all other testing is normal. Those with febrile seizures and drug related seizures may also be considered. In the United States, the Federal Aviation Administration does not allow those with epilepsy to get a commercial pilot license. Rarely, exceptions can be made for persons who have had an isolated seizure or febrile seizures and have remained free of seizures into adulthood without medication.
