In the mother’s womb and even after birth, babies are plagued often of hiccups, preterm infants spend an average of 15 minutes of the day. What is in adulthood, nuisance, for newborn may have an important function: hiccup triggers, according to a small study, a wave of brain signals, which could help the Baby to learn the regulation of Breathing.
Measurements of the brain activity of 13 neonates showed that the contractions of the diaphragm muscle cause hiccups a pronounced reaction in the cerebral cortex. The electroencephalogram (EEG) showed in the case of any "Hicks" a total of three brain waves, the last of which is probably caused by the noise. The researchers assume that the brain of a newborn baby can connect the sound from the hiccups with the feeling of the muscle contraction of the diaphragm. The results of the study are in the journal "Clinical Neurophysiology" appeared.
By hiccups babies learn to use their breathing to control
Dr. Lorenzo Fabrizi from University College London, said: "The activity that is the result of a hiccup, can help the brain of the baby. It learns how to monitor the respiratory muscles so that breathing can eventually be controlled by the diaphragm is deliberately moved up and down. The structure of such networks is a crucial milestone for the development of the newborn."
The same scientists had previously already set up the hypothesis that babies in the womb, may create mental pictures of your own body. You suspect that during the hiccups the same thing is happening for the inner body, and keep the hiccups in adults, therefore, a relic from the infancy.
