FIGURE 8-7 Prenatal Brain Development The developing human brain undergoes a series of embryonic and fetal stages. You can identify the forebrain, midbrain, and hindbrain by color (review Figure 8-3) as they develop in the course of gestation. At 6 months, the developing forebrain has enveloped the midbrain structures.
