WebNov 25, 2024 · What Happens in the Seconds and Minutes After a Stroke. Once a stroke happens, neurons—brain cells in charge of transmitting signals to the body—start dying. Neurologists believe that a person’s brain has as many as 100 billion neurons. Research shows the typical person loses 1.9 million neurons each minute that a stroke is untreated. When a nerve impulse (which is how neurons communicate with one another) is sent out from a cell body, the sodium channels in the cell membrane open and the positive sodium cells surge into the cell. Once the cell reaches a certain threshold, an action potential will fire, sending the electrical signal down the axon.
