Neural Tube Development

Neurons are formed in the neural tube during the proliferation stage of fetal brain development
Neurons migrate to their final destinations within the brain by the fourth month of gestation
Failure to properly close the neural tube during development results in birth defects such as anencephaly or spina bifida

Differentiation

During differentiation, neurons take on specialized roles based on their location and function
The specialization of neurons is influenced by chemical signals and environmental factors

Myelination

Myelin is a fatty substance which coats the axons of neurons
Myelination is essential for the efficient transmission of nerve impulses
Myelination occurs between birth and into adulthood
Myelination allows for faster and more efficient neuronal communication

Developmental Systems Theory

Developmental Systems Theory emphasizes the interconnectedness of biological, psychological, and social influences on development
Every aspect of development is influenced by multiple factors

Epigenesis

Epigenesis refers to the change in gene expression (not the actual DNA sequence) that happens due to external factors
Environmental influences impact gene expression

Gene Modification by Experience

Experience can modify gene activity through epigenetic processes such as methylation, acetylation, or histone modification
These processes can turn genes on or off

High Grooming Moms

High grooming (HG) moms have offspring with reduced stress levels due to epigenetic changes

Gene Chemistry Changes

Gene chemistry is altered by environmental influences through methylation, acetylation, or histone modification
These processes can affect gene activity and ultimately impact development
