Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

NEUROSCIENCE + BEHAVIORAL SCIENCE

YEAR 1 | PAGE 16A - NEUROANATOMY, TRACTS + LOCALIZATION CONCEPT MASTERY

LOCALIZE BEFORE YOU NAME THE DISEASE

Build every lesion as LEVEL/STRUCTURE -> TRACT/NUCLEUS -> DECUSSATION -> SIDE -> EXPECTED DEFICIT. Learn pathways by drawing the route and lesion pattern, not by memorizing isolated labels.

  • Draw corticospinal, DCML and spinothalamic pathways with where each crosses; predict ipsilateral vs contralateral findings above and below the lesion.
  • Localize brainstem/CN lesions by combining cranial-nerve findings with long-tract signs; separate central from peripheral patterns.
  • Differentiate cortex, internal capsule, basal ganglia, cerebellum, spinal cord, root, plexus, peripheral nerve and NMJ from examination clues.
  • Know major cerebral vascular territories and map focal deficits to the likely neuroanatomic region before naming the syndrome. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
