Proliferation, This is known as neurogenesis, and it is the production of new neurons and glia in the brain. An estimated 250,000 new neurons form in the ventricular zone every minute! This stage is crucial for generating the initial pool of cells that will later become neurons. , Differentiation, All neurons are initially identical, but as they mature, they develop distinctive shapes, depending on their destination and function. This stage ensures that neurons acquire their specific characteristics, such as shape and function.  , Migration, The movement of neurons from their place of origin to their final destination in the brain. Radial glial cells act as scaffolds to help guide migration. This stage positions neurons in the appropriate regions of the brain, forming proper brain structures., Synaptogenesis, The formation of synapses, the connections between neurons, allowing them to communicate with each other. This is key for establishing functional neural circuits and enabling brain activity. , Apoptosis, This is programmed cell death, which eliminates excess or damaged neurons. This is a normal part of brain development to ensure proper neuronal density. This stage removes unnecessary neurons, refining the neural network and optimizing brain function., Myelination, The process of forming the myelin sheath, a fatty layer around the axons of neurons, which speeds up the transmission of electrical signals. This improves the efficiency and speed of communication between neurons, essential for brain function. .
