Neurogenesis

Growing New Hardware

For decades, scientists believed the adult brain could not grow new neurons. We now know that Adult Neurogenesis occurs primarily in the Hippocampus (memory) and the Olfactory Bulb. This process is essential for learning, mood regulation, and pattern recognition.

BDNF: Fertilizer for the Brain

The key driver of neurogenesis is a protein called BDNF (Brain-Derived Neurotrophic Factor).

• The Trigger: BDNF levels are boosted by high-intensity exercise, intermittent fasting, and deep sleep.

• The Blocker: High sugar intake, chronic stress (cortisol), and sleep deprivation suppress BDNF, effectively halting the brain’s ability to update its hardware.

Plasticity vs. Rigidity

Neurogenesis is the biological basis of a “Growth Mindset.” Without new neurons, the brain becomes rigid, relying on old pathways and habits. To change your personality or learn a complex skill, you must biologically support the birth and survival of these new cells.
