Information in the brain travels at speeds of up to 268 miles per hour. Faster than your morning decision-making.

✓ TRUE FACT
The fastest nerve conduction (in heavily myelinated fibers) is about 120 m/s, which is roughly 268 mph or 432 km/h. Many signals travel much slower—especially in unmyelinated fibers (often 0.5–2 m/s). Speed depends heavily on axon diameter and myelin.
