Work

The nervous system in people and animals consists of many different cells. In cells, signals are conveyed by small electrical currents and by chemical substances. By measuring small variations in electrical charges at contact surfaces between nerve cells, or synapses, in the early 1950s John Eccles showed how nerve impulses are conveyed from one cell to another. The synapses are of different types, which has either a stimulating or inhibiting effect. A nerve cell receives signals from many different synapses, and the effect is determined by which type prevails.
