Neurogenesis — The Adult Brain That Keeps Growing
For most of the twentieth century, neuroscience held that the adult brain could not generate new neurons — that you were born with all the neurons you would ever have and could only lose them from that point forward. This was wrong. The discovery of adult neurogenesis changed everything about what is possible.
The Discovery
What Joseph Altman found and nobody believed
Joseph Altman published evidence for adult neurogenesis in rats in 1962 — using tritiated thymidine to label dividing cells in the brains of adult animals and documenting new neurons in the hippocampus and olfactory bulb. The finding was largely ignored or dismissed for thirty years. The dogma that adult brains do not generate new neurons was too entrenched.
The field changed definitively in the 1990s. Fernando Nottebohm documented massive neurogenesis in the song-learning regions of adult songbird brains — regions that grew in spring when birds were learning new songs and shrank in autumn. Elizabeth Gould and Charles Gross confirmed robust neurogenesis in the hippocampus of adult primates. In 1998, Peter Eriksson and Fred Gage confirmed adult hippocampal neurogenesis in humans using tissue from cancer patients who had received BrdU for diagnostic purposes. The dogma was dead.

The activities that grow new brain cells
What Kills Neurogenesis
The activities that suppress new growth
Chronic stress is the primary suppressor of neurogenesis. Sustained elevated cortisol directly inhibits the production of new neurons in the hippocampus — which is why chronic stress produces measurable hippocampal volume loss and impairs the memory and emotional regulation functions that depend on hippocampal integrity. Alcohol, opioids, and sleep deprivation also suppress neurogenesis significantly.
The implication is direct: the practices that the Infinitely Simple system is built around — consistent daily stillness, reduced cortisol through parasympathetic activation, improved sleep architecture through nervous system regulation — are precisely the conditions that promote hippocampal neurogenesis. The practice does not merely reorganize existing neural circuitry. It promotes the growth of new neurons in the region most associated with learning, memory, and emotional regulation.
The Framework Connection
New structure enabling new expression
The framework's account of the practice producing structural change in the brain — allowing new forms of ontological resonance through improved structural correspondence — is physically precise in light of neurogenesis research. The practice does not only reorganize existing neural connections. It promotes the growth of new neural tissue in regions critical for the capacities the framework describes: emotional regulation, memory integration, and the hippocampal-prefrontal connectivity that underlies conscious governance of subconscious pattern.
New neurons in the hippocampus are not randomly distributed. They integrate into existing circuits in ways that depend on activity — neurons that fire during learning and practice are more likely to survive and integrate. The practice is literally building the neural substrate for what it is practicing. The structural correspondence improves because the structure itself is growing in the direction the practice is pointing.
The framework that clarifies all of it
Infinitely Simple derives the nature of reality from first principles — no assumptions, no tradition, no faith required. Where ancient knowledge pointed at something real, the framework shows what it actually is.
