What is a flashing reflex?
Blink Reflex is a reflex that is designed to naturally protect his eyes. Most animals with eyes have some form of reflex blink and reflex is present since the animal first opens the eyes. Abnormalities in this reflex may indicate that there is a neurological problem and may increase the risk of eye damage, as the eyes can no longer protect reflexively.
Reflexes are involuntary actions. They allow the body to respond very quickly to potentially dangerous situations by taking defensive measures in some form. In the case of Blink Reflex, Blink is often over before someone consciously realizes that there is a risk. There are many other reflexes that appear at different stages of development.
Several different stimuli can trigger this reflex. Everything that touches the cornea causes someone to flash, and people usually flash when the objects seem to be on a collision course with the eye, such as when anomething is thrown in the direction of one's head. Very bright light also stimulates the reflex blink as wellLike loud sounds.
In the flicker process, more skulls are involved, as well as the brain stem. In a healthy person, a reflex blink appears in both eyes. If both eyes cannot flash, this may mean that there is a problem with one of the cranial nerves or the brain that inhibits the normal processing of Blink reflex. If someone does not answer at all to a stimulus that should trigger a blink or react slowly, it is also a sign of a neurological problem.
neurological tests may include a rapid assessment of Blink reflex to determine how the patient reacts to stimuli. This can be part of the control process in a patient who is assumed that it is not reacting or in a coma. It is also possible to assess the Blink Reflex in the test that includes the location of the electrodes around the eyes and providing very slight electrical stimulation when recording responses.
teachers representing children in reflexes in classCH biology often uses Reflex Blink as an example because it is easy to prove. One way to demonstrate reflex is to place a student behind a clear barrier and throw a light soft object like a cotton ball or wading paper on a barrier. The student usually flashes, although he is safe behind the barrier, because the eye perceives the approaching object as a threat.
