Shedding light on a period of chaos and character-building, neuroscientists are framing the teen brain to help support this critical period in development.

Your selections: Brain Development
Neuron formation begins in the earliest stages of human development. Signaling molecules “turn on” certain genes and “turn off” others, beginning nerve cell induction.
  • BrainFacts/SfN
Genes and the environment converge powerfully during early sensitive windows of brain development to form the neural circuits underlying behavior. Although most neuronal cell death occurs in the embryo, the paring down of connections occurs in large part during critical periods in early postnatal life.
  • BrainFacts/SfN
Once the neurons reach their final location, they must make the proper connections so that a particular function, such as vision or hearing, can emerge.
  • BrainFacts/SfN
Once the neural induction has occurred, the next step for new neurons is a journey to the proper position in the brain. This process is called migration, and it begins three to four weeks after a human baby is conceived.

Hormones are important messages both within the brain and between the brain and the body.

Insulation covering wires preserves the strength of the electrical signals that travel through them. The myelin sheath covering axons serves a similar purpose.
