When should I worry about my baby not making eye contact? You may have noticed that your newborn baby rarely blinks, but you have ever noticed why this happens. A 2010 study titled Optometry and Vision Science stated that the rate of spontaneous eye blink in human infants is less than four times per minute. At the same time, in adulthood, this rate gradually increases to 15-30 per minute. This is because blinking is regulated by the brain’s dopamine. It is one of the neurotransmitters that allows brain cells to communicate. So, studying it in infants can help us understand how this important neurotransmitter operates in fewer people. Let’s know about it.

What is the science behind blinking?

Studies have shown the link between dopamine and blinking, as conditions or medications that affect dopamine also alter blinking rates. People with schizophrenia, who are affected by too much dopamine, therefore tend to blink their eyelids more often. In contrast, in Parkinson’s disease, which is caused by the death of dopamine-producing neurons, blinking is markedly reduced. Taking medication to increase dopamine levels accelerates blinking rate. But dopamine also relies on a diverse set of other functions, ranging from control of movements and hormonal levels to learning and motivation. So, children’s blinking rates may reveal something about the development of the dopamine system and perhaps also reflect individual differences in some aspects of children’s nervous system.

Blinking in Babies

One of the main tasks of blinking eyelids is to keep the eyes lubricated, according to researchers, so babies tend to blink eyelids less because their little eyes don’t need much moisture. Another idea is that babies have new eyes Therefore, its working function is different from elders. At the same time, when you look visually or attentively, you blink less eyelids, which happens with infants. A similar phenomenon is seen in adults with computer vision syndrome, a condition in which the blink is reduced and the eyes become dry due to high visual demands of computer viewing.

Studied that it can be detected about infants by measuring the eyeblink of infants. Compared to brain imaging and other techniques, eyeblink is a weak measure, but it is a non-harmful one, the researchers believe. At the same time, dopamine activity can help in individual differences in personality, cognitive abilities, and attention to dopamine-related conditions such as attention deficit hyperactivity disorder (ADHD) or even Parkinson’s disease.

Why do infants have fewer naps than adults?

There are several theories that analyze that babies blink less eyelids than adults. One such theory is that blinking helps to keep the eye smooth but since babies have smaller eyes and sleep a lot more than adults, their eyes do not need that much lubrication and so they Take less naps. The eye blink rate (EBR) is a ‘non-invasive indirect marker’ of central dopamine function. Eye blinking is related, in part, to the child’s brain development. If dopamine levels are slightly lower, the eyelids blink less.

Do eyelid blink rates differ in infants?

Blinking varies from child to child, no doubt, but as the child grows older, the rate of blinking improves. In some children it is less, then it is faster in others. Therefore, there is no cause for concern.

Eyelid blink in infants may be indicative of autism spectrum disorder. According to a study by researcher Warren Jones, Emory University School of Medicine, Atlanta, published in the Proceedings of the National Academy of Sciences, blinking can index how busy people are with what they see. While children with autism are able to respond according to social context, those on the autism spectrum may often react after physical events because they have already occurred. On the other hand, if your baby is not blinking, can he have autism? You need to worry more than this. In about a year, if the child is not responding by name or is just staring at the items, symptoms may indicate blink rates. On the other hand, if you still have more concerns about the child, then take him to the eye specialist.
