While the majority of central nervous system neurons are formed during embryonic development, there are some areas of the brain where neurogenesis continues to occur after birth. One such area is the hippocampus, a region of the brain involved in learning and memory. In the hippocampus, new neurons are continuously generated from neural stem cells throughout life in a process known as adult neurogenesis.
Adult neurogenesis in the hippocampus has been shown to play a role in various cognitive functions, including learning, memory, and mood regulation. It is believed that these newly generated neurons contribute to the brain's ability to adapt and learn throughout life.
Another area of the central nervous system where neurogenesis occurs after birth is the olfactory bulb, which is involved in processing smells. New neurons are continuously generated in the olfactory bulb from neural stem cells located in the subventricular zone, a region of the brain lining the lateral ventricles.
In addition to neurogenesis, there is also ongoing synaptic plasticity in the central nervous system after birth. Synaptic plasticity refers to the ability of synapses (connections between neurons) to change in strength and efficiency in response to experience. This process is essential for learning and memory, as well as for adapting to changes in the environment.
Overall, while the majority of central nervous system neurons are formed during embryonic development, there are certain areas of the brain where neurogenesis and synaptic plasticity continue to occur after birth. These processes play important roles in learning, memory, and cognitive function throughout life.

Myelination:
- Myelin sheaths, insulating layers around nerve fibers, develop postnatally in the brain and spinal cord.
- Myelination provides faster signal conduction and allows for efficient neural communication.
Synaptic Pruning:
- Excess synapses formed during prenatal development are pruned postnatally through a process called synaptic elimination.
- This process fine-tunes neural circuits and removes synapses that are weak or unnecessary.
Dendritic Development:
- Dendrites, the branches of neurons that receive signals, continue to grow and elaborate postnatally.
- This increased dendritic complexity enhances neural connectivity and processing capacity.
Axonal Branching:
- Axons, the extensions of neurons that transmit signals, undergo branching postnatally.
- This branching increases the number of targets that neurons can communicate with and facilitates the formation of complex neural networks.
Spine Density:
- Dendritic spines, small protrusions where synaptic contacts are made, increase in number and density postnatally.
- Spine density reflects the strength and plasticity of synaptic connections.
Neurogenesis:
- Limited neurogenesis, the birth of new neurons, occurs in specific regions of the brain postnatally.
- This neurogenesis contributes to the development and plasticity of brain regions involved in learning and memory.
Other Areas of Development:
- Glial Cell Maturation: Glial cells, which support and protect neurons, continue to develop and differentiate postnatally.
- Blood-Brain Barrier Formation: The blood-brain barrier, which protects the brain from harmful substances in the blood, fully establishes after birth.
- Neural Integration: Different brain regions and neural circuits gradually integrate and coordinate their functions postnatally.
