When you will see into a baby’s eyes, and you might notice sometime Babies rarely blink. As we know adults, blink about 15 times a minute, on average. But newborns and infants blink rarely — only a handful of times every minute, with some babies blinking as infrequently as once a minute. The average is two or three blinks That’s because blinking is regulated by the brain’s dopamine, one of the neurotransmitters that allow brain cells to communicate. So, blinking in babies could help us better understand how this important neurotransmitter operates in infants. We know the link between dopamine and blinking, as conditions or drugs that affect dopamine also change blinking rates. People with schizophrenia, which may be caused, in part, by too much dopamine, blink more frequently. As in Parkinson’s disease, which is caused by the death of dopamine-producing neurons, blinking is markedly decreased. Taking medicine to raise dopamine levels brings blinking rate back up. But dopamine also underlies a diverse set of other functions, from the control of movements and hormonal levels to learning and motivation. So, babies’ blinking rates may reveal something about the development of the dopamine system and perhaps even reflects individual differences in some aspects of babies’ nervous systems, there will potentially spontaneous blink What does this all mean for babies? Because one function of blinking is to keep the eyes lubricated, researchers have proposed that babies blink less than we do because their small eyes don’t need as much lubrication.. the reduced blinking rate in newborns is due to an underdeveloped dopamine system.
