““All of that was eventually shown—there’s considerable adult neuro-genesis in the hippocampus (where roughly 3 percent of neurons are replaced each month) and lesser amounts in the cortex.22 It happens in humans throughout adult life. Hippocampal neurogenesis, for example, is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injuryfn9 and inhibited by various stressors.fn10,23 Moreover, the new hippocampal neurons integrate into preexisting circuits, with the perky excitability of young neurons in the perinatal brain. Most important, new neurons are essential for integrating new information into preexisting schemas, something called “pattern separation.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Adult hippocampal neurogenesis continues throughout life, supporting learning, memory, and pattern separation, but is vulnerable to stress and injury.
In simple terms: New brain cells help us learn and remember, but stress can hinder them.
Promote learning, exercise, and enrichment to support brain health.
