Occurs at a logarithmic rate (slowing down). This is the multiplication of cells to begin creating a web of neurons. The overproduction of neurons is slowed down by a process called apoptosis. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/ https://academic.oup.com/book/7871/chapter-abstract/153087688?redirectedFrom=fulltext -
Early development of the brain has begun between 2 and 4 weeks after conception. Neurulation is the process of transferring the neural plate into the neural tube. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/ -
Refers to the contact point between between two neurons. This is when these connections are formed. Peaks of synaptogenesis occur at different points around the brain, this is when it begins. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/ -
The growth of neural connections or synapses. (notes) Cells are either retracted, or become complete neurons. 40-60% of neurons are retracted. "The development of axons is facilitated by growth cones, small structures that form at the edge of an axon."- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/ -
Birth of the child. -
Cells group and move to needed areas. Motor function can begin to be developed when beginning. https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/cell-migration#:~:text=Cell%20migration%20is%20an%20evolutionarily,Advances%20in%20Cancer%20Research%2C%202016 -
The brain reaches 50% of its potential size around the age of 1. https://coverthree.com/blogs/research/kids-brain-development -
Myelination occurs and axons of neurons are wrapped in fatty cells. Timing is dependent on each part of the brain but begins two years after birth. In some parts of the brain, this occurs up to adolescence. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/ -
Synaptic gaps are no longer functional thus no re uptake. Neurons die and less connections are made. This is the removal of of synaptic connections. Pruning
(notes and https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3722610/) -
Each neuron has formed 15,000 synapses. A toddler's brain has about 1 quadrillion synapses. https://coverthree.com/blogs/research/kids-brain-development
