Building Brains

Building Brains surveys foundational neurobiological research on brain repair, glial cell architecture, life-extension compounds, and dendritic arborization, following the 2016 Church of Neuroscience research series by the Van Kush Family Research Institute. It is the close companion of Neurogenesis, Neuroprotectants, and Synaptogenesis, focusing on approaches to traumatic brain injury (TBI) and cognitive longevity.

Summary

The monograph gathers four core research strands:

Life-Extension Compounds: Cycloastragenol, alongside the author's speculative primer hypothesis.
Carnosine: An endogenous neuroprotective dipeptide acting in synergy with antioxidant cofactors.
Glial Cells ("The Other Brain"): Shifting focus from purely neuronal transmission to astrocytes and oligodendrocytes (drawing upon Marian Diamond's anatomical studies of Albert Einstein's brain).
Dendrite Growth: Stimulating synaptogenesis and dendritic branch elongation via ampakines.

Cycloastragenol and the Primer Hypothesis

Cycloastragenol, a triterpenoid saponin aglycone extracted from the root of Astragalus membranaceus, has been studied in molecular biology for its ability to transiently activate telomerase (the enzyme complex that elongates chromosomal telomeres). The author flags a speculative hypothesis—untested in clinical medicine—concerning the potential priming of repair pathways via chemically-induced dimerization (CID) concepts. The Library preserves this strictly as the author's historical speculative hypothesis, noting that potent prescription immunosuppressants (like tacrolimus) carry severe clinical contraindications and must never be self-administered.

Carnosine: Endogenous Peptide Neuroprotection

L-Carnosine ($\beta$-alanyl-L-histidine) is an endogenous dipeptide concentrated in high concentrations in mammalian brain and skeletal muscle tissue:

Antioxidant and Antiglycation: Carnosine scavenges reactive oxygen species (ROS) and reactive nitrogen species, buffers intracellular lactic acid, and inhibits advanced glycation end-product (AGE) formation.
Synergy with Vitamin E: Preclinical models demonstrate that carnosine's membrane-protective and cellular longevity properties are significantly multiplied when paired with lipid-soluble alpha-tocopherol (vitamin E).

Glial Cells: Astrocytes and Oligodendrocytes

Historical neuroscience treated glia (from the Greek for "glue") as passive structural filler holding neurons in place. However, post-mortem histological analysis of Albert Einstein's brain revealed a dramatically higher ratio of glial cells to neurons in the prefrontal and parietal cortices, sparking modern investigation into glial computation:

Oligodendrocytes and Remyelination:

** Oligodendrocytes synthesize and maintain the lipid myelin sheath insulating central axons. In traumatic brain injury, demyelination exposes bare axons to metabolic death.

** Cellular screens identified the over-the-counter antihistamine clemastine as an agent that stimulates oligodendrocyte precursor cell (OPC) differentiation, accelerating functional remyelination.

Astrocytes and Adenosine Regulation:

** Astrocytes form the tripartite synapse, regulating the metabolic microenvironment, clearing excess synaptic glutamate, and modulating extracellular adenosine signaling.

Dendrites and Ampakines

The final thread focuses on dendrites—the arborized receiving arms through which neurons form synaptic junctions:

Ampakines (AMPA Receptor Modulators): Compounds like aniracetam and research ampakines (CX-614) act as positive allosteric modulators of AMPA-type glutamate receptors.
By slowing receptor deactivation, ampakines stimulate the activity-dependent synthesis of Brain-Derived Neurotrophic Factor (BDNF), promoting rapid dendritic spine branching without excitotoxicity.
2-AG Neuroprotection: The article highlights 2-arachidonoylglycerol (2-AG) as the brain's native on-demand circuit breaker against traumatic brain injury (TBI) and post-traumatic cerebral edema.
