  2. Blepharospasm - Wikipedia

    en.wikipedia.org/wiki/Blepharospasm

    Blepharospasm is often associated with dry eyes, but the causal mechanism is still not clear. [16] [8] Research in New York and Italy suggests that increased blinking (which may be triggered by dry eyes) leads to blepharospasm. [24] [25] A case control study in China found that blepharospasm aggravated dry eyes. [26]

  3. Blinking - Wikipedia

    en.wikipedia.org/wiki/Blinking

    Blinking is a bodily function; it is a semi-autonomic rapid closing of the eyelid. [1] A single blink is determined by the forceful closing of the eyelid or inactivation of the levator palpebrae superioris and the activation of the palpebral portion of the orbicularis oculi, not the full open and close.

  4. Flicker vertigo - Wikipedia

    en.wikipedia.org/wiki/Flicker_vertigo

    Blink rapidly; Experience rapid eye movements behind closed eyelids; Lose control of fine motor functions; Experience muscle rigidity; These effects are typically very minor and will most often subside within seconds once exposure to the strobe effect has ceased, though residual nausea and minor disorientation may be felt for several minutes.

  5. Meige's syndrome - Wikipedia

    en.wikipedia.org/wiki/Meige's_syndrome

    Spasm means "uncontrolled muscle contraction". The term blepharospasm ['blef-a-ro-spaz-m] can be applied to any abnormal blinking or eyelid tic or twitch resulting from any cause, ranging from dry eyes to Tourette's syndrome to tardive dyskinesia. The blepharospasm referred to here is officially called benign essential blepharospasm (BEB) to ...

  6. Corneal reflex - Wikipedia

    en.wikipedia.org/wiki/Corneal_reflex

    Stimulation should elicit both a direct and consensual response (response of the opposite eye). The reflex occurs at a rapid rate of 0.1 seconds. The purpose of this reflex is to protect the eyes from foreign bodies and bright lights (the latter known as the optical reflex). [2] The blink reflex also occurs when sounds greater than 40–60 dB ...

  7. Visual release hallucinations - Wikipedia

    en.wikipedia.org/wiki/Visual_release_hallucinations

    Also, interrupting vision for a short time by closing the eyes or blinking may be helpful. [2] It is possible for a stressful life event to alter the disposition of hallucinatory experiences as well as the emotional experiences (from unconcerning to concerning) in CBS. [22]

  8. Startle response - Wikipedia

    en.wikipedia.org/wiki/Startle_response

    This also showed the response latency, or the delay between the stimulus and the response recorded, was found to be about 14 milliseconds. The blink of the eye which is the reflex of the orbicularis oculi muscle was found to have a latency of about 20 to 40 milliseconds. Out of larger body parts, the head is quickest in a movement latency in a ...

    Eyeblink conditioning (EBC) is a form of classical conditioning that has been used extensively to study neural structures and mechanisms that underlie learning and memory. ...
