This chapter discusses the neuroplasticity of the brain, focusing specifically on the reproduction of new neurons among adults. Neuroplasticity refers to changes in neural pathways and synapses due to changes in behavior, environment, neural processes, thinking, and emotions. It plays a major role in optimal neural functioning. When adults are subjected to behavioral and environmental changes, several parts of their brain produce and host new neurons. These include the hippocampus, a key structure for spatial memory, and the olfactory bulb, the first relay in the olfactory system. In both instances, new neurons are formed from a germinative zone of neuronal stem cells, the subgranular zone of the dentate gyrus of the hippocampus and the subventricular zone bordering the cerebral ventricles in the anterior part of the brain.

Keywords:   neuroplasticity, neural pathways, hippocampus, germinative zone, stem cells, the dentate gyrus, subgranular zone, subventricular zone
