blink reflexes การใช้

• From the blink reflex, it contains the R1 ipsilateral and bilateral R2 component.
• At high stimulation strengths, this often excites the trigeminal sensory afferents and triggers a blink reflex.
• A tick attached to the side of the face may cause loss of blink reflex, corneal ulceration and an ocular discharge.
• The eye's natural defense against sudden exposure to bright light is the blink reflex, which is not triggered by infrared sources.
• Where the eye does not close completely, the blink reflex is also affected, and care must be taken to protect the eye from injury.
• The upper facial muscle ME responses could not be innervated by TMS and the low threshold of blink reflexes often interferes with the nature of corticobulbar influences.
• Cortical damage, particularly cerebral lesions, can cause loss of the menace reflex whilst leaving the other blink reflexes, such as the dazzle reflex, unaffected.
• Light at this wavelength is rather dangerous to vision, since it can be focused by the eye's lens onto the retina, but the light is invisible and does not trigger the blink reflex.
• I realize that IR lasers are invisible-so there is a risk of someone staring into the thing without knowing it's there, they don't invoke the blink reflex or close down the iris.
• Studies have found that even low-power laser beams of not more than 5 mW can cause permanent retinal damage if gazed at for several seconds; however, the eye's blink reflex makes this highly unlikely.
