Human brain develops fastest after birth
The fastest speed changes occur immediately after birth, the infant's brain grows at an average rate of 1% / day. This speed slowed down to 0.4% / day at the end of the 90-day test.
A group of researchers led by experts from the University of California (USA) has used advanced brain scanning techniques for 87 healthy children from birth to 3 months of age.
They found that the fastest rate changes occurred immediately after birth, the infant's brain grew at an average rate of 1% / day. This speed slowed down to 0.4% / day at the end of the 90-day test.
The infant brain grows at an average rate of 1% / day.
The researchers also discovered that the cerebellum - the brain region is involved in motor control, which has the fastest growth rate, doubling its original size after 90 days. The slowest developing brain region is hippocampus , a structure that plays an important role in memory and memory formation.
Scientists say the difference reflects the importance of motor skills and memory in newborns. Brain scan results also revealed, the brains of newborn boys grow faster than the brains of their peers.
In addition, at birth, premature babies also have a brain 4% smaller than the brains of full-term, full-term babies. Despite growing at a faster rate, their brains are still 2% smaller than the brains of full-term, full-term babies after 3 months.
According to experts, collecting such data can help them identify early signs of developmental disorders in people, such as autism. Researchers are now planning to investigate whether the use of drugs and alcohol during pregnancy changes the child's brain size at birth.
