## Summary

Brain, mind, cognition — a clinical tour of the most complex object known to science. Key sections include: NEUROSCIENCE 86 billion cells, talking.; The neuron — an electrical wire that thinks.; The action potential — a 1 ms electrical spike.; Synapses — chemical conversation, ~100 trillion of them.; Anatomy — one brain, many regions, two halves.; Sensory & motor — the brain’s I/O bus.; Memory — how the brain holds onto time.; Broca, Wernicke, and what aphasia teaches us.; Cajal vs. Golgi — the 1906 Nobel.; The modern toolkit..
