Final answer:
True. Both the hippocampus and olfactory bulb are capable of growing new neurons.
Step-by-step explanation:
True. Research in the last few decades has shown that neurogenesis, the birth of new neurons, continues into adulthood. This occurs in the hippocampus, a brain structure involved in learning and memory. Both the hippocampus and olfactory bulb have been found to be capable of growing new neurons. For example, about 1000 new neurons develop in the hippocampus each day, and an increase in the number of surviving new neurons in the hippocampus has been correlated with better learning in rats. Similarly, the olfactory bulb, which is responsible for processing smell information, contains bipolar olfactory neurons that extend from the olfactory epithelium and can regenerate.
