The temporal lobe (aptly named because it’s near the temples) controls hearing, smell, and language comprehension.
It works with the amygdala and hippocampus to enable learning, memory, and emotional responses.
Hearing is the first sense to develop completely in babies. Within minutes of birth a newborn will startle and cry at loud noises.
That’s because much of the early physical development occurs long before your baby is born.
Research shows that the inner ear is the only sense organ to fully form before birth. The inner ear reaches its adult size by the middle of pregnancy.
Smell also develops early in your infant’s life. Researchers say that premature babies born at 7 months’ gestational age respond to smells, which means that the necessary tools to detect scents are functional even before birth.
Newborns react to smells on their first day, making faces at unpleasant smells, like rotten eggs, and smiling at sugary smells.
By the end of his first week, a nursing baby will turn toward a pad soaked in his mother’s milk but ignore pads from other nursing mothers.
