343 lesson blocks and more than forty custom interactive diagrams, written and structured for this course rather than assembled from existing summaries. Read how it was built and validated.
Five units, taught in sequence
Each unit assumes and builds on the one before it, moving from the cellular anatomy of the autonomic nervous system to the principles of functional restoration.
Inside Unit 1: from the cell to the neuraxis, the complete autonomic circuit map.
Every concept, taught at three levels
The same mechanism is built up three times, so understanding holds whether a clinician reasons intuitively, anatomically, or from first principles.
Clinical analogy
Intuitive models drawn from Dr. Keiser's clinical teaching, so a complex circuit makes sense before a single Latin term appears.
Structural neuroanatomy
Where each structure physically sits, what it connects to, and how the wiring runs, grounded in Netter's atlas.
Deep mechanism
Receptor pharmacology, neurochemical coding, and integrative reflex arcs. The level at which you understand why the system breaks, not just that it does.
Understanding is verified, not assumed. Every concept is assessed across four escalating tiers: recall at the block level, tracing a full physiological pathway, a module synthesis exam, and a localization lab that asks the learner to reason from symptoms back to the failing structure. Progress is gated, so no one advances on recognition alone.
Built on the literature, not on opinion
Every mechanistic claim traces back to the primary literature, and anything that could not be supported did not survive into the final text. The work of the researchers who built this field runs through the course as the mechanisms they established are taught, applied, and tested.
