What is neurogenesis?

Neurogenesis refers to the process of forming new neurons in the brain. This process is essential for brain development and has significant implications for learning, memory, and overall brain health. Neurogenesis primarily occurs in specific regions of the brain, such as the hippocampus, which is critically involved in memory formation.

Research has shown that neurogenesis can be influenced by various factors, including environmental conditions, stress, physical activity, and even certain types of learning. The ability of the brain to generate new neurons is particularly important during early development but can continue to some extent in adulthood, offering potential pathways for recovery from brain injuries and various neurological conditions.

In contrast, other options describe processes that do not involve the creation of new neurons, such as neuron death, the increase of synaptic connections, or the shrinking of brain cells, which are not representative of neurogenesis and do not capture the essence of creating new neural pathways in the brain.
