Our brain is most complex device in whole universe. More than 10 billions neurons work in brain factory and each neuron communicate with other neurons. They share information in form of checmail ions. Checmail ions such as Cl-, Na+, Mg+ and K+ are use in this process.
Neurons want to share information with their friends neurons. Each neurons have axons, synapse , dendrites and cell body. Cell body is similar to cell of an organism. Cell body have cell membrane which protect cell from rupture, so that cell perform their own functions. When a cell membrane contact with electrode O(100 mv) voltage they exchange checmails ions. When Na+ enter in cell membrane it depolarize cell membrane state O(0mv). Another gate release K+ or Ca2+ from cell membrane. This is called repolarization O(-55mv).
A spike/action potential is a result of depolarization and repolarization. In other words it's is fluctuation of voltage with respect to time.
