how many neurons are in the brain at birth

Center on the Developing Child, Harvard University, USA Just as a weak foundation compromises the quality and strength of a house, adverse experiences early in life can impair brain architecture, with negative effects lasting into adulthood. “Different stimuli and tasks, such as hearing a lullaby or reaching for a toy, help establish different neural networks,” wrote Yudhijit Bhattacharjee in an article for National Geographic.Įarly experiences affect the development of brain architecture, which provides the foundation for all future learning, behaviour, and health. Scientists are rapidly untangling how a child goes from seeing images when just born to being able to feed, talk, play and communicate by the age of three. Parents, caregivers and family members all have a part to play in helping to form a baby’s brain. The future of a child’s developing brain is in our hands. When a baby is born, 100 billion neurons – or brain cells – have already been produced. Birth to age threeĪ child’s brain undergoes a rapid period of development during these three years, producing 700 new neural connections every second. While most mothers in developed countries are given every opportunity to stimulate their unborn child, nourish it and protect it, it’s often a very different story for pregnant women in the developing world. The long-term effects of early stress, poverty, neglect and maltreatment were well-documented and virtually uncontested years before scientists could “see” them with brain-scanning tools. Neuroscientists can now identify patterns in brain activity that appear to be associated with some types of negative early experiences.
