Although the human brain has 100 billion nerve cells at birth, newborns are capable of little beyond the most vital functions like breathing and sucking. The infant's ability to see, hear, touch, smell and taste is primitive. Higher cognitive functions like attention, reasoning, language and conscious memory are absent. Scientific research proves that a baby's brain cells are only weakly connected. What firms up these connections are the experiences and stimulation the baby receives in the critical first five years. While every child is born with the capacity for higher thinking, how fully the brain and mind develops is determined in equal measure by genetics and by the richness of the environment surrounding the child. This is true of all environments, both rational and emotional - cuddling, touching, comforting, bouncing, hugging, smiling, soothing, talking and playing are as vital as mental stimulation. Every aspect of a child's evolving brain can be affected by the quality of the world to which he or she is exposed. "What's Going on in There?" demonstrates the innumerable ways in which parents can actually help children develop better brains.
