What is defined as the formation of new neurons?

The correct term for the formation of new neurons is neurogenesis. This process is essential for growth, development, and the maintenance of brain function throughout an individual's life. Neurogenesis primarily occurs in specific regions of the brain, such as the hippocampus, which is critical for learning and memory. Understanding neurogenesis is important in various fields, including behavioral health, as it relates to brain plasticity, recovery from injury, and adaptability to new experiences.

Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections; however, it does not specifically refer to the generation of new neurons. Neurosynthesis is not a widely recognized term in the context of neurobiology, and neurodevelopment pertains to the entire process of brain development from conception through adulthood, which includes but is not limited to neurogenesis. Thus, neurogenesis accurately captures the specific process of new neuron formation.
