Neurogenesis Activation is the biological process characterized by the proliferation and differentiation of neural stem cells into new, functional neurons within specific regions of the adult brain, such as the hippocampus. In the context of wellness, this is closely tied to cognitive health, memory consolidation, and mood regulation, which are profoundly influenced by the neuroendocrine environment. We seek interventions that promote this plasticity for enhanced neurological resilience. It represents the brain’s capacity for self-renewal.
Origin
This concept originates from neuroscience, challenging earlier dogma that neurogenesis ceased after development, focusing on plasticity in the adult central nervous system. The activation component suggests an intentional stimulation of this latent capacity. Its relevance to hormonal health stems from recognizing that factors like BDNF, estrogen, and exercise modulate this process significantly. The term highlights dynamic neurological potential.
Mechanism
Activation often occurs downstream of systemic changes that increase neurotrophic factor availability, notably Brain-Derived Neurotrophic Factor (BDNF). Certain physiological stressors, when managed appropriately, or specific exercise modalities can trigger the signaling cascades necessary for progenitor cell division and migration. Hormones like IGF-1, released systemically, can cross the blood-brain barrier or influence local glial cell support, thereby facilitating the integration of new neurons into existing circuitry.
