Brain Development
Plasticity
Plasticity itself is not unique to humans, but the degree to which our brains are able to adapt is.
BrainFacts/SfN
Induction: The Making of a Neuron
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
Critical Periods in Early Life
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
Making Connections
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
Migration: New Nerve Cells on the Move
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.
BrainFacts/SfN
Hormones: Communication between the Brain and the Body
Hormones are important messages both within the brain and between the brain and the body.
BrainFacts/SfN
Myelination and Paring Back
Insulation covering wires preserves the strength of the electrical signals that travel through them. The myelin sheath covering axons serves a similar purpose.
BrainFacts/SfN
Inside the Teenage Brain
What's going on inside the teenage brain? This Frontline television special explores how science may unlock answers to that question.
