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