Description

HBOT at moderate pressures (1.5-2.0 ATA) optimally induces BDNF expression, activating PKCζ-mediated DHHC2 palmitoyltransferase to stabilize PSD95 at excitatory synapses via enhanced palmitoylation, directly rescuing CA3-CA1 hippocampal synaptic function.

Dimension Scores

How to read this chart: Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential. The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength), green shows moderate-weight factors (safety, competition), and yellow shows supporting dimensions (data availability, reproducibility). Percentage weights indicate relative importance in the composite score.
