The present study measured the normal blink rate (BR) variations in relation to behavioral tasks in 150 healthy volunteers (70 males and 80 females; aged 35.9 ± 17.9 years, range 5–87 years). The subjects were videotaped in a standard setting while performing three different tasks: resting quietly, reading a short passage, talking freely. The mean BR was computed during each task; the data were compared by means of analysis of variance and Student's t tests. Mean BR at rest was 17 blinks/min… 
Blink rate variability during resting and reading sessions

TLDR
It is discovered that compared to the resting sessions, reading sessions are characterized by a lower number of blinks, and the average of inter-blink intervals increases during reading/memorization, thus longer inter-Blink intervals could be associated with a mental workload.

TLDR
The median SBR during visual fixation was lower than that reported previously in 5-14 years- old children during rest or 11-20 years-old subjects during quiet conversation, and was even lower during vertical smooth pursuit and saccades tasks.
Spontaneous Eye Blink Analysis in the Normal Individual
TLDR
The closing time was significantly longer than the opening time for all ages and both genders, and Elderly individuals and women had significantly longer closing times.
Relationship between Eye Blink Frequency and Incremental Exercise among Young Healthy Men
TLDR
The analysis showed that blink frequency and eye closure time were determined by a group of factors (the value of cycle ergometer load power, heart rate, body weight, adipose tissue mass, fat-free mass, and total body water and body surface ratio).

TLDR
It is proposed that the pattern of spontaneous eyeblink activity where there are similar intervals between each eyeblink event should be referred to as a “normal” (rather than symmetrical) pattern and should be considered as the normal eyeblinks activity, both from a physiological and statistical perspective.
Blink Rate, Blink Amplitude, and Tear Film Integrity during Dynamic Visual Display Terminal Tasks
TLDR
Blink rate, blink amplitude, and tear film stability were compromised during the most dynamic visual display terminal task, suggesting a negative influence of not only the cognitive aspects of the task, but also of the rate at which new visual information is presented.
Blink frequency and duration during perimetry and their relationship to test-retest threshold variability.
TLDR
A wide range of blink frequencies was observed during perimetric testing, and although no blink parameters showed significant influence on threshold variability, when the blinks overlapped with a stimulus presentation, the probability of seeing was reduced.
Analysis of blink rate in patients with blepharospasm
TLDR
It is indicated that specific features of BR can be associated with BS, suggesting that the analysis of BR might be helpful for the diagnosis of BS in early stages.
The Hawthorne Effect in Eye-blinking: Awareness that One’s Blinks are Being Counted Alters Blink Behavior
TLDR
It is concluded that informing a subject that his eye blinks are being counted exerts a modest but significant acute influence on blinking activity, but critically does not appear to confound blink rate over prolonged tasks.

TLDR
The correlation between eye-blink rate and central dopamine activity may also prove clinically useful in selected neuropsychiatric disorders.
Blinking and Thinking
TLDR
In the experiment reported here, blinking was measured while the activity of operational memory was manipulated with mental load kept constant and the rate of blinking was significantly reduced when the cognitive operation of internal counting was being performed.
Ontogeny of spontaneous blinking and of habituation of the blink reflex
TLDR
The inverse relationship of spontaneous blinking rate and number of blink reflexes to habituation in early childhood and in disorders of dopamine transmission suggests that spontaneous blink rate and habituation of the blink reflex reflect maturation and integrity of dopaminergic circuits in the brain.

Physiology of normal and abnormal blinking.
TLDR
The failure to associate Dyskinesias (except levodopa-induced dyskinesia) with increased blinking, indicates that the pathophysiology of these conditions may not involve hyperactivity of CNS dopamine systems.
Eye‐Blink Rate in Tourette's Syndrome
TLDR
Results are not consistent with elevated brain dopamine activity in adult patients who have Tourette's syndrome, and blink rate did correlate, however, with both the number and severity of tics.

The coexistence of tics and dystonia.
TLDR
Nine patients with motor and phonic tics and other features of Tourette's syndrome, who developed persistent dystonia in addition to their tics, suggest that some patients with tics may have an increased risk for dySTONia.
