Myelination
The development of the myelin sheath around the axons of neurons, which increases the speed of signal transmission.
Synaptic Pruning
The process of eliminating excess neurons and synapses to increase the efficiency of neuronal transmissions.
Dendritic Development
Formation and branching of dendrites to increase the surface area for possible synaptic connections.
Genetic Influences on Brain Development
The role of genes in guiding the development, organization, and function of the brain.
Migration
Movement of neurons from their origin to their final position in the brain.
Experience-Dependent Plasticity
Changes in the neural structure and function due to learning and interaction with the environment.
Neural Tube Closure
The process where the neural plate rolls into a tube that will develop into the brain and spinal cord.
Environmental Influences on Brain Development
External factors such as nutrition, stress, and exposure to toxins, which can affect brain development.
Axon Growth and Guidance
The extension of axons from neurons to their correct targets, guided by molecular cues.
Neurotrophic Factors
Proteins that support the growth, differentiation, and survival of neurons during development.
Experience-Expectant Plasticity
The development and refinement of brain circuits that are anticipated to be present in the typical environment.
Plasticity
The brain's ability to change and adapt as a result of experience throughout life.
Neural Proliferation
The rapid cell division of neural progenitor cells in the neural tube.
Neural Differentiation
The process where neural stem cells become specialized neurons or glial cells.
Critical Periods
Specific time windows during development when the nervous system is particularly sensitive to certain environmental stimuli.
Neural Plate Formation
Early neural tissue that eventually forms the neural tube, which is the precursor to the central nervous system.
Apoptosis
Programmed cell death that is essential for the removal of excess neurons and the shaping of the developing nervous system.
Synaptogenesis
The formation of synapses between neurons in the nervous system.
