Intensity Dependent Neurogenesis

Meaning

Intensity Dependent Neurogenesis describes the critical phenomenon where the rate of generating new neurons from neural stem cells in specific brain regions, most notably the hippocampus, is directly correlated with the intensity and complexity of the physical or cognitive stimulus applied. Not all activity is equally potent; high-intensity, complex, or novel stimuli are specifically required to maximize the proliferative and survival signals for these new neurons. This crucial mechanism is central to activity-dependent brain plasticity, long-term memory formation, and cognitive enhancement.
