Question

Quizplus · Accepted Answer

By 24 weeks of gestation, fetuses have developed enough to respond to sound and can recognize the mother's voice as soothing. Brain waves are recorded on an electroencephalogram around 24 to 28 weeks, not at the end of the first trimester. Eyes are first receptive to light at around 20 to 22 weeks, not 34 to 36 weeks. At term, the fetal brain is only about one quarter the size of an adult brain, not one third.
